  • API 6A Manual Adjustable Choke Valve

    API 6A Manual Adjustable Choke Valve

    Our Plug and Cage style choke valve features a tungsten carbide cage as the throttling mechanism with a protective steel carrier around it

    Outer Steel carrier is for protection against impacts from debris in the production fluid

    The trim characteristics are an equal percentage that provides superior flow control, however, we can provide the linear trim as well on-demand

    Pressure-balanced trim considerably reduces the torque required to operate the choke

    Plug is fully guided at the ID of the sleeve and is rigidly attached to the stem to resist any induced vibration damage

  • API Low Torque Control Plug Valve

    API Low Torque Control Plug Valve

    The plug valve is mainly made up of the body, the hand wheel, the plunger and the others.

    The 1502 union connection is applied to connect its inlet and outlet to the pipeline (this can be custom-made according to different requirements). the precise fit between the valve body and the liner is ensured by means of cylindrical fitting, and the sealant is inlaid through the outer cylindrical surface of the liner to make sure that it is hermetically sealed.

    The cylindrical meal-to-meal fit between the liner and the plunger is adopted to ensure a high fitting accuracy and thereby reliable sealing performance.

    Note: even under a pressure of 15000PSI, the valve can be opened or closed with ease.

  • API 6A Double Expanding Gate Valve

    API 6A Double Expanding Gate Valve

    Plastic/chevron packing stays clean and free from contaminants to reduce maintenance costs.

    Tight mechanical seal is assured with parallel expanding gate design.

    This design provides upstream and downstream sealing simultaneously which is not affected by pressure fluctuation and vibration.

    A double-row roller thrust bearing on the stem makes operation easy, even under full pressure.

  • High Pressure Wellhead H2 Choke Valve

    High Pressure Wellhead H2 Choke Valve

    Interchangeability of parts to construct a positive, adjustable, or combination choke.

    Bonnet nut has rugged integrally forged lugs for hammering nut loose.

    Built-in safety feature that releases residual pressure in the choke body before the nut is fully removed. The inside of the choke body is vented to atmosphere after the bonnet nut is partially removed.

    Interchangeability of component parts for a particular pressure range. For example, the same blanking plugs and bonnet assemblies are used in nominal 2000 through 10,000 PSI WP

  • Drum & Orifice Type Choke Valve

    Drum & Orifice Type Choke Valve

    The body and side door are made of alloy steel.

    Choke-plate design, heavy-duty, diamond-lapped tungsten-carbide plates.

    Tungsten-carbide wear sleeves.

    Regulate the flow quite accurately.

    Versatile for onshore and offshore applications.

    Long life for service.
