Pneumatic gas quick shut-off valve

氣動(dòng)煤氣快速切斷閥 is a new generation of fast cut-off butterfly valve designed based on the actual working conditions of gas.
(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.
Applicable temperature: ≤ 200 ℃
Applicable media: Heating furnace gas, blast furnace gas, converter gas, etc
One way opening and closing time: DN ≤ 1200, S ≤ 2 seconds; DN ≥ 1400, S ≤ 3.5 seconds
