Manual Gate Valve
•Nominal Bore: 1.13/16"~9" (46mm~230mm)
•Working medium: oil, natural gas, mud ,including H2S,CO2
•Working temperature: -46°C~121°C(Class LU)
•Material class: AA, BB, CC, DD, EE, FF , HH
•Specification level: PSL 1-4
•Performance level: PR 1-2
•Mental-to-mental seal is used between bonnet and body, gate and seat, seat and body.
•The surface of gate and seat is welding overlay with hard alloy, which has feature of
corrosion resistance and washing resistance.
•The balanced stem can balance the stem load, reduce load of stem thread and bearing
to decrease operating torque.
•The bonnet and stem are designed with back seal, which can replace stem sealing
under pressure.
•One side of bonnet is designed with sealant injection valve.
•Rising stem structure can indicate open and close of valve.
•Complete with different pneumatic (hydraulic) actuator upon user’s requirements.
•Working pressure 2000PSI~20000PSI
