Pneumatic gas quick cut-off butterfly valve, also known as gas quick cut-off valve, is a new generation of quick cut-off butterfly valve designed according to the actual working conditions of users. It is a parking cut-off protection valve used in emergency situations of pipelines. The pneumatic quick cut-off butterfly valve is composed of a metal sealed triple eccentric butterfly valve and a single acting spring reset actuator, which has the characteristic of quick closing. It can be closed within 1 second and is widely used in heating furnace gas, blast furnace gas, converter gas, dust removal and combustible gas pipelines that require quick cut-off< br/>

Pneumatic gas quick cut-off butterfly valve features:

(1) Using rubber sealing rings, with good sealing performance and no leakage;

(2) Adopting a double eccentric conical sealing structure, with a larger and tighter sealing mechanism and automatic wear compensation function for the sealing pair:

(3) Using a double acting cylinder for propulsion, it has a large opening and closing torque, fast action speed, rapid valve opening and closing, and low flow resistance loss.

(4) The cylinder adopts a buffer design, which improves its service life; The cylinder is equipped with a muffler to reduce noise pollution to the environment. Suitable for situations where rapid cut-off is required in combustible gas pipelines such as blast furnace gas and converter gas& nbsp;
