Pneumatic Butterfly Valves Triple Eccentric Quadruple Eccentric Hard Seal Butterfly Valves

Chinese wafer butterfly valves are compact, lightweight valves widely used in industrial piping systems. They feature a ductile iron body, stainless steel disc, and EPDM or NBR seat. The wafer design allows easy installation between flanges, making them a popular, cost-effective choice for on/off and throttling control of water, air, and mild chemicals in general industrial applications.
