Brief introduction of grooved soft seal gate valve:

The grooved soft seal gate valve adopts grooved connection, which is easy to install, fast and convenient to Maintain, and cost-saving; it has vibration isolation and sound insulation and can overcome the difference caused by the different axis of the pipeline connection within a certain angle range, and can solve the expansion caused by hear and contraction caused by cold.                          

Characteristics of grooved soft seal gate valve:

  1. simple in structure, easy to manufacture and maintain.
  2. overall rubber coated. Ductile iron gate valve has characteristics of overall rubber coated, great sealing Performance, accurate physical dimensions, which can guarantee the zero leakage, long service life, and small flow resistance.
  3. corrosion resistant. The inside of the valve body is coated with non-toxic epoxy resin, which is anti-corrosive and rust resistant. That kind of gate valve not only can be used for drinking water piping line systems,also can be used for wast water delivery pipe line systems.

Applications of grooved soft seal gate valve:

This kind of gate valve is widely used in the water supply and drainage of fluid delivering pipeline, and to control the fluid in the pipeline projects in fire protection, air conditioning, gas, petroleum, chemical industry, water treatment, municipal administration, shipping building and other industrial projects.
