BAODINGVALVULA shares that soft seal gate valve is a kind of most commonly used water supply valve with small fluid resistance and strong sealing performance.
Product Features:
Body material is from cast iron (GGG) and wedge is fully covered by NBR or EPDM. Spindle material is stainless steel. valve is designed such a way that provide safe sealing. By turning the stem clockwise, with the elastic design of the sealing wedge gives absolute tightness with minimum torque.
Corrosion protection:
All casting parts are coated with epoxy powder RAL 5015 or 5005 by electrostatic method.
Application of soft-seal gate valve:
soft sealing gate valves are used for closing and opening fluid flow. The Gate valves soft sealing can be used for fluids up to 70°C such as drinking water and untreated water and also compressed air per Certificate DVGW-G260 (Other media on request). Application fields are water supplies, dams, water treatment, pumping stations, pipe lines, industries, power plants, waste water and irrigation.
Hydrostatic test pressure (bar) according to DIN EN 12266-1
Pressure drop coefficient when the valve is fully open.

Advantages of soft sealing gate valves:
1 delicate appearance, light weight: the valve body is made of ball black cast iron, the weight is about 20%~30% less than the traditional Gate Valves weight, transportation, installation and maintenance is convenient;
2. Rubber binding of the gate: the gate is integrated with high-quality rubber for internal and external binding. Rubber vulcanization technology ensures accurate geometric size of the gate after vulcanization.
3 channels without groove design: channel without groove design structure, sediment, iron filings, sundries, etc. will not be deposited in the valve bottom groove, sealing life is long.
