The FC series flat gate valves are widely used in wellhead devices, oil production trees, manifolds and pipelines.
Full-bore design effectively eliminates pressure drop and eddy current.
Metal seals are adopted between the valve body and the valve cover, the gate and the valve seat, and between the valve body and the valve seat.
The valve cover and valve stem are designed with an inverted seal, facilitating the replacement of the valve stem sealing ring under pressure.
The surface spray welding layer of the valve plate and valve seat is hard alloy, which has good wear resistance and corrosion resistance.
A sealing grease injection valve is provided on one side of the valve cover to replenish the sealing grease and improve the sealing and lubrication performance between the gate plate and the valve seat.
It can be equipped with drive devices of various specifications.
