Electric explosion-proof butterfly valve

Hebei Shengyi ProductionElectric explosion-proof butterfly valveThe main connection methods are flange type and clamp type. It is an important execution unit in the field of industrial automation control. Main advantages: simple structure, small size and light weight, low cost, installation in high-altitude tunnels, and adjustable flow medium. The fluid resistance is small, and the effective flow area is large when the electric explosion-proof butterfly valve with a medium to large diameter is fully opened. The opening and closing are quick and effortless, and the disc can be rotated 90 degrees to complete the opening and closing. Due to the nearly equal force of the butterfly plate hand medium on both sides of the shaft, the torque direction is opposite, so the opening and closing torque is small. Good sealing can be achieved under low pressure. The sealing materials of the electric explosion-proof butterfly valve include nitrile rubber, fluororubber, edible rubber, and PTFE lining, so the sealing performance is good, and it has excellent sealing performance in any situation (up to zero leakage). Electric explosion-proof butterfly valves can be widely used in industrial process automatic control systems in industries such as food, environmental protection, light industry, petroleum, chemical industry, teaching equipment, papermaking, and electricity.
