Features & Benefits

• Large Seat opening and high lift-disc for higher flow rates at a lower pressure loss
• Separate flow and control chambers permit positive closing without springs; and only nominal cost for spring assist opening for low-pressure and self-draining applications
• Cost-effective solution both in initial cost, as well as lifetime maintenance expenses
• Separate diaphragm chambers protects the diaphragm from the flow stream, while allowing the valve to be serviced in-line
• Pre-formed, stress relieved diaphragm minimizes fatigue, maximizes valve responsiveness and diaphragm lifetime
• All internal parts in contact with media are made of composite materials
• Can be actuated with either air or water as control fluid
• Designed for water treatment applications including those requiring acids, caustic and harsh chemicals that would rapidly corrode metal valves
