AquaMatic K55 Series Composite Diaphragm Valves with glass-filled thermoplastic body and cap are designed for water treatment applications including those requiring acids, and harsh caustic chemicals that would rapidly corrode metal valves. Their unique Y-pattern design with a large seat opening and high lift disc permits higher flow rates at lower pressure loss than competitive valves. This product is manufactured in the United States of foreign and domestic parts.
