Product Description

Rubber Seated Gas Butterfly Valves 

The rubber soft sealed gas butterfly valve is made of rubber-sealed butterfly valve with double eccentric structure, and the bi direction sealing performance is more stable. It is the first choice for the old pipeline to be modified,repaired and matched with soft seal

1.This series of gas butterfly valves adopt double eccentric structure, the valve seat is stainless steel, the sealing pair is opened and closed instantly, the process friction is reduced, and the service life of the valve is prolonged.

2.This series of gas butterfly valve adopts half-shaft structure, with high strength, large overflow area and small flow resistance, saving energy.

3.The rubber seal ring can adjust the interference amount of the seal pair through the pressure plate, so that the seal specific pressure is controlled in the optimal state, and when the rubber seal ring is damaged, the pressure plate can be removed on the pipeline

4.This series of butterfly valves are equipped with the latest synchronous indicating mechanism, which can clearly indicate the opening and closing state of the valve in a convenient and conspicuous position.

Gas butterfly valve can be used in petrochemical, food, medicine, textile,paper making, hydro power, ship, water supply and drainage, metallurgy and other systems, all corrosive, non-corrosive gas, liquid, semi-fluid and solid powder pipelines and containers can be used for regulation and closure, can be installed at any location.

The rubber soft seal gas butterfly valve is mainly divided into the spiral double-eccentric flange type rubber butterfly valve, the pneumatic double-eccentric flange type rubber butterfly valve, the electric double-eccentric flange type rubber butterfly valve,
