  • Check Valves-Image
    Check Valves - (1934 companies)
    The mechanics of check valve operation are relatively simple. Most check valves contain a ball that sits freely above the seat, which has only one through-hole. The ball has a slightly larger diameter than that of the through-hole. When the pressure behind...

  • Butterfly Valves-Image
    Butterfly Valves - (1236 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. Butterfly valves are quarter-turn... Search by Specification | Learn More
