Product Description

China wafer sandwich electric butterfly valve manufacturer,factory and supplie,wafer sandwich electric butterfly valve is composed of soft or metal seated butterlfy valve wafer type and on-off or regulating type actuator, which control of water and other media compatible with the materials of construction.Standard unit of wafer sandwich electric butterfly valveis power-to-open and power to close, stays in last known position with loss of power. On receipt of a continuous voltage signal, the motor runs and via a flat gear system rotates the disc. The motor is automatically stopped by internal cams striking micro switches at both open and closed positions. On receipt of a reversing continuous signal, the motor turns in the opposite direction reversing the valve position.

Wafer sandwich electric butterfly valve feature
·  Rugged epoxy coated ductile iron/WCB body with stainless steel disc for maximum corrosion resistance
·  Unique wave line seat and special disc shape reduces the torque required to turn the valve and extends the seal life
·  Lower torque also reduces the size of the actuator, lowering the cost of the valve assembly
·  Two piece shaft design enhances the flow capacity of the valve
·  Valves direct mount to actuator with standard ISO5211 international standards
