Full Bore Design can efficiently solve the problems of pressure drop and vortex, and slows down the process of erosion resulting from the solid particles in the fluid.
Metal-to-metal seal is used between bonnet and body, gate and seat, body and seat.
The surface of gate and seat is overlaid with hard alloy makes the valve with high performance of anti-corrosion and anti-wear.
This kind of valve is designed with balancing stem, with which can balance stem load, also, reduce the load of stem thread and bearing to lower the operating torque.
The stem designed with back seal construction, can easily replace stem seal ring under pressure.
One side of bonnet is designed with injection valve in order to replenish sealing grease, moreover, to improve seal and lubrication performance of gate and seat.
The rising stem structure can indicate the position of valve open/close.
Can complete with different pneumatic (hydraulic) actuator as per user's requirements.
