Weir Type Diaphragm Valve

The diaphragm valve is a stop valve that uses a diaphragm as a start and stop part to close the flow channel, and cut off the fluid and separate the inner cavity of the valve body from the inner cavity of the valve cover. Diaphragm is usually made of elastic, corrosion-resistant, and non-permeable materials such as rubber and teflon. It has a simple structure, good sealing, corrosion resistance and low fluid resistance.
