Electric standard flange turning on and off lever

　　Electric standard flange on the open and close the valve stem rotation is not only to enhance the operation of the valve stem packing is not easy to damage, sealed and reliable. And disc cone pin fixed, expansion, and to prevent the design, in order to avoid wafer flange bar and electrical standard flange butterfly compaction damage accident bar collapse.

　　Connecting flange, wafer connection, welding connection, connection chip chip. Manual, electric, pneumatic, hydraulic, electro-hydraulic actuator, can realize remote control and automation. Advantages 1, convenient and rapid sluicegate, fluid resistance is small, save labor, usually can operate. 2, with a simple structure, small size, short length of the structure, small size, light weight, suitable for large diameter wafer flange door. 3, transport slurry fluid accumulation at least in the pipeline outlet. 4, low pressure, can achieve a good seal. 5, good regulation performance. 6, fully open, the wafer flange more effective flow, fluid resistance is small. 7, the opening and closing torque is very small, the role of the media on both sides of the shaft is basically the same, the resulting torque direction is opposite, so more efforts to open and close. 8, sealing surface materials commonly used in rubber, plastic, and therefore good sealing performance. 9, convenient installation. 10, electric standard flange flexible advantages, you can choose manual, electric, pneumatic, hydraulic way
