Valve Type
   Your choices are...         
   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. 
   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. 
   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. 
   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. 
   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. 
   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. 
   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. 
   Regulators       Regulators maintain a constant outlet pressure. 
   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. 
   Solenoid Valves       Solenoid valves are electro-mechanical devices that utilize a solenoid to control valve activation.
