Help with Valve Repair Services specifications:

   Your choices are...         
   Angle Valves       Angle valves have an inlet and outlet at 90 degrees, or a control mechanism that enters the valve body at an angle to conserve room and allow maximum flow. 
   Balancing Valves       Balancing valves are mixing valves that maintain a constant water temperature by balancing hot and cold supply lines. They are able to compensate for a pressure drop in either supply line and can maintain a consistent temperature. Balancing valves are sometimes referred to as pressure-balancing valves. 
   Ball Valves       Ball valves provide tight shut-off and characterizable control. They have high rangeability due to the design of the regulating element, without the complications of side loads typical of butterfly or globe valves. Advantages include ease of operation and high flow, high pressure, and high temperature capabilities. Disadvantages include low cleanliness and an inability to handle slurries. 
   Bellows Valves       Bellows valves have a bellows seal between the media and the valve's bonnet. Bellows valves provide a contaminant-free, positive shut-off for high purity gas / fluid systems. 
   Block and Bleed Valves       Block and bleed valves are configured so that flow through the valve is blocked at both the inlet and outlet, and a small port is provided to drain or depressurize the space between. This configuration is often required to isolate high-pressure sections of a system to facilitate safe maintenance or rapid depressurization.  These valves are also referred to as double block and bleed valves. 
   Blow Off Valves       Blow off valves (BOV) are used to blow pressure off the pipeline and in purging operations. Blow off valves are also used in the automotive industry to relieve pressure in the piping from the turbo to the inlet manifold when the throttle is backed off. When used in this way, they are referred to as compressor bypass valves. 
   Butterfly Valves       Butterfly valves control the flow of gas or liquid with a disk which turns on a diametrical axis inside a pipe, or by two semicircular plates hinged on a common spindle, permitting flow in only one direction. They are used as throttling valves to control flow. Butterfly valves offer a rotary stem movement of 90 degrees or less in a compact design. Unlike ball valves, butterfly valves do not have pockets in which fluids may become trapped when the valve is closed. Advantages include suitability for chemical services, small dimensions, and high coefficient of flow. Disadvantages include low cleanliness and the inability to handle slurries. 
   Cartridge / Manifold Valves       Cartridge valves are directional control valves that are inserted into manifolds to provide a cost-effective, compact system design. 
   Check Valves       Check valves are self-activating safety valves that prevent process flow from reversing. 
   Choke Valves       Choke valves are designed to control flow at a linear rate with respect to the actuator. They are often used within combustion engines and in the oil industry. 
   Clamshell / Bin Gate       Clamshell or bin gate valves are used to cutoff, restrict, or control the flow of solids with a disc or gate that swings across the flow path.  Some solids valves use inflatable sealing elements to reduce wear while maintaining a good seal. These valves are referred to by a number of names, including swing gate valves, rolling blade gate valves spherical disc valves, and double or single clamshell valves. 
   Control Valves       Control valves or proportional valves are power-operated devices used to modify fluid flow or pressure rate in a process system. 
   Cryogenic Valves       Designated by manufacturer as being applicable to extreme cold applications such as for liquid gas and refrigerants. 
   Diaphragm Valves       Diaphragm valves are related to pinch valves, but use an elastomeric diaphragm instead of an elastomeric liner to separate the flow stream from the closure element. Instead of pinching the liner closed to provide shut-off, the diaphragm is pushed into contact with the bottom of the valve body.  Diaphragm valves are excellent for controlling the flow of fluids which contain suspended solids. They also offer the flexibility of installation in any position. Diaphragm valves are used widely in the pharmaceutical, food processing, and water treatment industries. Advantages include cleanliness and tight shut-off. Disadvantages include low pressure and temperature limits, and multi-turn operation. 
   Directional Valves       Directional valves direct or prevent flow through selected passages. 
   Diverter Valves       Diverter valves change the direction of the flow of a medium to two or more different directions. 
   Dome Valves       Dome valves have a dome-shaped mechanism to stop the flow of media. They are used in abrasive and toxic applications. Dome valves also feature an inflatable seal to ensure tight sealing action. These industrial valves require little maintenance because they have few parts that wear. 
   Double Flap Airlock / Flap       Double flap airlocks, flap valves, louver-type dampers, two-way flap valves, double butterfly valves are used to shut-off the flow of bulk material.  The flaps can open sequentially to maintain the airlock between the hopper and conveyor or process unit. 
   Drain Valves       Drain valves allow the removal of surplus fluid from a system or container. 
   Excess Flow Valves (EFV)       Excess Flow Valves are application specific valves that are used to shut off flow in the event of an unusually high flow condition. 
   Float Valves       Float valves automatically open or close as the level of a fluid changes. A float that rests on the top of the liquid operates these valves mechanically. 
   Foot Valves       Foot valves are a type of check valve with a built-in strainer. They are used at the point of liquid intake to retain liquid in the system. 
   Gate / Knife Valves       Gate or knife valves are linear motion valves in which a flat closure element slides into the flow stream to provide shut-off. Gate valves are usually divided into two types: parallel and wedge-shaped. The parallel gate valve uses a flat disc gate between two parallel seats, upstream and downstream. Knife valves are of this type, but with a sharp edge on the bottom of the gate to shear entrained solids or separate slurries. Advantages include the ability to cut through slurries. Large sizes are commonly available. Disadvantages include pressure limitations, lack of cleanliness, and low shut-off. 
   Globe Valves       Globe valves are linear motion valves with rounded bodies, from which their name is derived.  They are used widely in industry to regulate fluid flow in both on/off and throttling service.  Advantages include precise throttling and control, as well as high-pressure limits. Disadvantages include low cleanliness and the inability to handle slurry. 
   Iris Valves       Iris valves function like the iris mechanism in a camera. As the valve closes, the material is pushed out of the way.  On some iris valves, the mechanical components are enclosed in a flexible sleeve to protect against the ingress of particles. 
   Metering Valves       Metering valves are capable of accurately controlling the flow of a fluid. 
   Mixing Valves       Mixing valves combine the flows of two or more inlets into a single outlet for applications such as temperature or concentration control. 
   Needle Valves       Needle valves have a slender, tapered point at the end of the valve stem that is lowered through the seat to restrict or block flow.  Fluid flowing through the valve turns 90 degrees and passes through an orifice that is the seat for a rod with a cone shaped tip. These small valves are widely used to accurately regulate the flow of liquids and gases at low flow rates. The fine threading of the stem and the large seat area allow for precise resistance to flow. Advantages: Precise control. Disadvantages: low-pressure limitations, no slurries. 
   Pilot Valves       Pilot valves are small valves that are used to operate larger valves. They generally require less applied power to turn the larger valve than if the larger valve was operated independently. Solenoid valves are often used as pilot valves. 
   Pinch Valves       Pinch valves include any valve with a flexible elastomer body that can be pinched closed, cutting off flow, using a mechanism or fluid pressure. Pinch valves are full bore, linear action valves so they can be used in both an off/on manner or in a variable position or throttling service. Some typical applications for pinch valves are medical, pharmaceutical, wastewater, slurries, pulp, powder and pellets. They can effectively control the flow of both abrasives and corrosives, as there is no contact between metal parts and the transport media. Advantages: Streamlined flow, high coefficient of flow. Disadvantages: limited materials, low shut-off capabilities, low pressure limits. 
   Plug Valves       Plug valves, also called cock or stop-cock valves, date back to ancient times where they were developed for use in citywide Roman plumbing systems. Today, they remain one of the most widely used valves for both on/off and throttling services.  Their design is fairly simple; the body is comprised of three main parts: body, cover and plug.  The plug is a cylindrical, tapered, or generally cone-shaped device that can be raised or lowered within the seat to maintain, restrict or completely shut off flow.  The valve is opened by rotation with the plug itself being the only element that is capable of movement. Advantages: Easy operation, medium to high flow, good shut off. Disadvantages: Low cleanliness, inability to handle slurry. 
   Poppet Valves       Poppet valves open and close ports with a sealing device composed of a disk, cone or sphere that is pressed against the seating surface using a spring. 
   Pressure Relief Valves       Pressure relief valves are self-actuated safety valves designed to relieve excess upstream pressure from the line. 
   Safety Valves       Safety valves contain a thermal sensing component that opens or closes in response to temperature changes or close a line and stop the flow of material when a pre-set condition occurs. 
   Sampling / Dispensing Valves       Sampling valves or dispensing valves are fitted to a reactor or pipeline to allow a small sample of a fluid to be withdrawn for testing or mixing. Some sampling valves ‘trap’ a small quantity of fluid in a chamber, and only this fluid is released when the valve is operated. 
   Sanitary / Hygienic Valves       Sanitary and hygienic valves are used in aseptic applications in the dairy, brewing, beverage, pharmaceutical and bio-chemical industries. 
   Servo Valves       Servo valves provide closed loop flow or pressure response to an electrical or electronic control signal. They are used in air, gas, and liquid applications. 
   Shut Off Valves       Shut off valves close a line to stop the flow of material when a pre-set condition occurs such as excess flow or a pressure pulse from a broken line or a temperature change from an idle burner. 
   Solenoid Valves       Solenoid valves are electro-mechanical devices that utilize a solenoid to control valve activation. 
   Spool Valves       Spool valves use a rotary or piston-like spool for actuation. The spool, or spools, rotate or slide back and forth to block and uncover ports in the housing. 
   Toggle Valves       Toggle valves are used for on-off control in moderate pressure and temperature applications. They feature a toggle mechanism for valve actuation. 
   Vacuum Relief / Anti-siphon Valves       Vacuum relief valves are automatic valves that open or close a vent to relieve a vacuum, depending on whether the vacuum is above or below a predetermined value. They are frequently used in hot water supply systems. An anti-siphon valve is a valve, usually plastic or brass, used to control the flow of water in one direction. It will prevent a backflow of water into the potable water supply.
