KD647X-1 pneumatic quick gas shut-off valve

This series of butterfly valves is a new generation of quick cut-off valves designed based on the actual working conditions of customer on the basis of absorbing advanced technologies at home and abroad. Its characteristics: (1) adopts rubber sealing ring, which has good sealing performance and no leakage; (2) adopts double eccentric conical sealing structure, which has a tighter and tighter sealing mechanism and an automatic compensation function for seal wear; (3) adopts double Acting on the cylinder to drive, the opening and closing torque is large, the action speed is fast, the valve opens and closes quickly, and the flow resistance loss is small; (4) The cylinder adopts a buffer design to increase the life span; the cylinder is equipped with a muffler to reduce noise pollution to the environment. It is suitable for flammable gas pipelines such as blast furnace gas, converter gas, etc., where quick cut-off is required.   Main technical performance: Nominal pressure: 0.10MPa…
