Gate valve is a kind of full-bore valve with single valve plate that can be used in double flanged or threaded connection, or used together with the actuator produced by the company.

Structural Characters：

· Bi-directional sealing structure, making valves serve longer;

· Reversed sealing and grease filling check valve design, making replacement of parts above bonnet under pressure more convenient;

· Parts contacting with fluid are all sealed with materials other than rubbers, which makes the sealing performance better and service life longer;

· Equipped with valve up/down display, which can directly demonstrate the state of non-rising stem valve.
