Features:
The wafer end butterfly valve adopts a wafer center plate structure, which is composed of a butterfly wafer type body, a butterfly wafer type plate, a shaft, a valve seat and a transmission device. The mechanism is simple and compact, small and lightweight, and is easy to transport, install and disassemble; it can open and close at 90°, and the switch is quick and easy to operate. It has small torque, is labor-saving and lightweight; has good sealing performance, long service life, and can achieve zero leakage;the wafer end butterfly valveflow characteristics are close to a straight line and has good adjustability.
The wafer end butterfly valve is rubber sealed. When closed, the valve plate and valve seat have good sealing performance, excellent two-way sealing performance, and small torque. The butterfly wafer type maintains 100% zero leakage under working pressure, and the friction between the valve plate and valve seat seal is small. The valve The valve shaft drives the valve plate, and the valve plate rotates 90°. The butterfly wafer type plate opens and closes flexibly, without jamming or jumping, and with small torque.
