Wafer Concentric Butterfly Valve can be used as adjusting and intercepting equipment on non-corrosive gas, liquid, semiliquid and solid powder tube, and vessel.
simple and compact in structure, light in weight, easy to assemble and repair;
Small operation torque, turn 90掳 portable rapid opening and closing;
Small flow resistance, the energy saving effect is good;
Reliable sealing, leakage is zero, long service life.
Large diameter can be increased due to the increase of torque, which can be increased by adding a turbine head or electric actuator. Electric actuators can be equipped with common type, household type, explosion-proof type and regulating type according to different working conditions, which can realize remote control and computer networking.
This valve must be equipped with butterfly flange. Put the butterfly valve into the middle of the special flange at both ends of the pipeline, and use the double head bolt through the pipeline flange and clamp butterfly valve to lock tightly, then it can be used normally. For specific use, please consult ZECO Valve Group.
