Products/Services for Info On Valve

  • Solenoid <B>Valves</B>-Image
    Solenoid Valves - (860 companies)
    Solenoid valves are devices that use a solenoid to control valve activation. Actuation methods include electric, electro-hydraulic, electro pneumatic, and pneumatic. Unpowered states include normally open and normally closed. In a tandem center... Search by Specification | Learn More
  • Gas <B>Valves</B>-Image
    Gas Valves - (434 companies)
    Gas valves are used to handle and control the flow of gaseous media such as liquefied petroleum and natural gas. They are made of metal or plastic and vary in terms of valve size, pressure rating, number of ports, and flow. Connection types consist... Search by Specification | Learn More
  • Hydraulic <B>Valves</B>-Image
    Hydraulic Valves - (602 companies)
    ...valves have a slender, tapered point at the end of a valve stem. Poppet valves open and close ports with a sealing device that includes a disk, cone, or sphere. Pressure relief valves remove excess upstream pressure. By contrast, regulators maintain... Search by Specification | Learn More
  • Globe <B>Valves</B>-Image
    Globe Valves - (674 companies)
    ...trade-hardware.com. As their name suggests, globe valves are linear motion valves with rounded globular shaped bodies. Since their shape is similar to other valve bodies, positive identification must be made based on internal piping. Recently globe... Search by Specification | Learn More
  • <B>Valve</B> Actuators-Image
    Valve Actuators - (731 companies)
    Valve actuators mount on valves and, in response to a signal, move a valve to a desired position using an outside power source. There are several basic types of valve actuators: manual, electric, pneumatic, and hydraulic. Manual valve actuators do... Search by Specification | Learn More
  • Butterfly Valves - (1033 companies)
    Butterfly valves control flow through a circular disc or vane by turning the valve's pivot axis at right angles to the direction of flow in the pipe. They are normally used as throttling valves to control flow. How To Select A Butterfly Valve. Image... Search by Specification | Learn More
  • Gate Valves - (959 companies)
    ...slides into the flow stream to provide shut-off. Gate valves and knife valves are designed to minimize pressure drop across the valve in the fully opened position and stop the flow of fluid completely. The direction of fluid flow does not change... Search by Specification | Learn More
  • Control Valves - (1520 companies)
    ...element has the ability to start and stop flow as well as stop along any position of the valve stroke to regulate the process of flow, temperature or pressure. Control valves are the final control element in the system and are used in conjunction... Search by Specification | Learn More
  • Ball Valves - (1725 companies)
    Two-Piece. Ball valve T-Port valve. Image Credit: Assured Automation | Cameron | Dwyer. Ball valves are quarter-turn, straight-through valves that have a round closure element with matching rounded seats that permit uniform sealing stress. The valve... Search by Specification | Learn More
  • Valve Positioners - (175 companies)
    Valve positioners compare a control signal to a valve actuator 's position and move the actuator accordingly. They are used with both linear valves and rotary valves. When a control signal differs from the valve actuator 's position, the valve... Search by Specification | Learn More
