  • Valve Actuators-Image
    Valve Actuators - (852 companies)
    Valve actuators mount on valves and, in response to a signal, move a valve to a desired position using an outside power source. Selecting the correct valve actuator will increase uptime, reduce maintenance costs, and increase plant safety. Most...
  • Solenoid Valves-Image
    Solenoid Valves - (966 companies)
    Solenoid valves generally have two ports: an inlet and an outlet port. There are several types of solenoid valves that include three or more ports. Three-way solenoids are used to operate single-acting actuators, such as diaphragm actuators...
  • Butterfly Valves-Image
    Butterfly Valves - (1223 companies)
    Design Tip: If working with a corrosive material, put the stem seal on the inside of the valve to prevent the material in the system from coming into contact that with the valve stem. Valve Actuator. The valve actuator operates the stem and disc to open...
  • Hydraulic Valves-Image
    Hydraulic Valves - (672 companies)
    ...and their actuators please read Industrial Valves. Specifications. Performance specifications for hydraulic valves include: Valve sizes are typically measured in inches (in). Pressure ratings are usually measured in pounds per square inch (psi). Ports...
  • Gate Valves-Image
    Gate Valves - (1131 companies)
    ...manual valves. This is especially true if the valve uses a rising stem. Most of the time gate valves should be installed horizontally (perpendicular to the ground) with the manual actuator in the top position. This allows for easy access for maintenance...
  •  
    Check Valves - (1892 companies)
    ...stopper is spring and bushing actuated to keep the movement "quiet." A ball check valve uses a free-floating or spring loaded ball resting in a seat ring as the closure element. Cone check valves use a free-floating or spring loaded cone resting...
  •  
    Gas Valves - (509 companies)
    ...are designed for both on/off and throttling functions. Other types include poppet valves, pressure relief valves, regulators, safety valves, and sampling valves. Compressor valves as well as servo, shut off, solenoid, spool, toggle, underwater, and vacuum...
  •  
    Ball Valves - (2032 companies)
    ...consists of a ball shaped disc. The valve is opened by a quarter turn of the actuator. The turn lines the hole in the ball parallel to the flow so the media is able to pass through the valve. When the valve is closed the ball is rotated so the hole...
  •  
    Electric Rotary Actuators - (183 companies)
    Electric rotary actuators drive components rotationally via electromagnetic power. They typically have control and indexing capabilities. Electric rotary actuators drive components rotationally via electromagnetic power from a motor. They typically...
  •  
    Air Valves - (755 companies)
    ...but are not suitable for sanitary applications. Butterfly valves permit flow in only one direction. Check valves are self-actuating and prevent the reversal of process flow. Diaphragm valves separate the flow of water from the closure element. Directional valves...
