Valve

Valve

    There are many different types of valves available, each suited to a particular purpose. Valves are made from a wide variety of materials and found in virtually every industrial process.

    Ball Valves are a form of quarter-turn valves which use a hollow ball that pivots to control flow through it. The handle aligns with the flow when open, is perpendicular to it when closed, making for easy visual confirmation of the valve's status. Ball Valves are durable and reliable, closing securely even after long periods of disuse, making them a popular choice for shutoff and control applications.

    Ball Valves are stocked in sizes from 1/4" to 6".
    Available in a variety of materials including brass, carbon steel, and stainless steel.
    All Ball Valves listed here have a teflon seat.
    Both Reduced-Port and Full-Port Ball Valves are stocked.
    Both flanged and threaded ball valves are available.

    Threaded & Socket Weld Ball Valves---Ball Valves ¼”- 4” One, Two & Three Piece

    Flanged Ball Valves---1/2” – 10” Flanged One Piece & Two Piece


    Butterfly Valve is a form of a quarter-turn valve which uses a metal disk for the closing mechanism. The disk is positioned in the center of the pipe and is open when the surface of the disc is parallel to the flow, closed when the disc is perpendicular to the flow. All of the Butterfly Valves we stock are designed to be connected between two flanges.

    Lug type Butterfly Valves connect between two flanges and have threaded inserts so that each flange can be bolted to the valve.
    Wafer type Butterfly Valves are sandwiched between two flanges, but the valve is not bolted to either flange.
    Butterfly Valves are stocked in sizes from 2 to 12 inches.
    All have a BUNA seat and Nickel plated disc..

    High Performance Double Offset Butterfly Valves

    Resilient Seated Butterfly Valves

     

    Check Valve is a device that allows liquid or gas to flow through it in only one direction. Check Valves generally work automatically and have no external controls. Other names for Check Valves are clack valves, one-way valves, and non-return valves.

    Check Valves are stocked in sizes from 1/2" to 4".
    Available in a variety of materials including brass, bronze and cast steel.
    We carry both threaded and flanged end Check Valves.
    Both Horizontal-Swing and Inline-Spring-Loaded Check Valves are stocked.

    Gate Valves open by lifting a round or rectangular gate out of the path of the fluid. Generally, Gate Valves are used with liquids and are designed to be either fully opened or closed. When fully open, the typical gate valve has no obstruction in the flow path, resulting in lower friction loss than other types of valves.

    Gate Valves are also known as sluice valves.
    Rising Stem Gate Valves provide a visual indication for the valve status.
    Gate Valves are stocked in sizes from 1/2" to 6".
    Available in a variety of materials including brass, bronze and cast steel and forged steel.
    We carry Threaded, Socket Weld and Flanged End Gate Valves.

    Non-Return Valves

    Non-returnable valves received their name from what they do. These values allow fluid, whether in the form of liquid or gas, to flow in only one direction. These one-way valves only restrict the flow in one direction, while allowing full and unimpeded flow in the opposite direction.There are different types of non-return valves such as: spring-loaded, clapper and swing type. These specific valves are used mainly in heating and cooling systems but can also be seen in water systems and boilers.
