Soft seal gate valve can be used in chemical industry, petroleum, sewage treatment, urban water supply and drainage and many other fields. It is used in a strictly sealed environment under normal temperature and pressure. Not suitable for high pressure, high temperature and corrosion, harsh and wear working conditions. Before understanding how to use soft seal gate valves, we must first understand the system of soft seal gate valves. Soft seal gate valve is divided into soft seal flange gate valve and soft seal sheet gate valve, both of which have the advantages of excellent sealing performance.

Soft seal gate valves are usually made of EPDM, nitrile butadiene rubber, and Teflon. Soft seal gate valves are suitable for flow cutting and controlling water, oil, steam and other acidic and alkaline substances in pipelines. The medium of EPDM rubber is usually water or steam; Nitrile rubber is suitable for oily media; Vinyl fluoride is suitable for some corrosive media pipes.

Soft seal gate valve actuators usually include handles, turbine heads, pneumatic actuators and electric actuators. The use of a soft seal gate valve is simple by operating the actuating device on the body to drive the stem motion. The stem drives the disc to rotate to realize the opening and closing of the valve. The selection Angle of the disc is between 0 and 90°. Different driving methods are selected according to different calibers and pressures.
