Review

Description

Groove type non rising stem elastic seat seal gate valve is a kind of soft seal gate valve. It is a new type of gate valve product produced by introducing foreign technology. It has many advantages that traditional valves do not have and has a wide range of applications. It has the advantages of light switch, reliable sealing, good elastic memory and long service life. Groove gate valve is light in weight. The body is made of nodular cast iron, which is about 20% – 30% lighter than traditional gate valve. It is easy to install and maintain. Widely used in water, sewage, construction, petroleum, chemical, food, medicine, textile, power, shipping, metallurgy, energy systems and other fluid pipelines as regulating and intercepting devices.
