The unique Y-pattern design with large seat opening and high lift disc permits higher flow rates at lower pressure loss than other comparable valves. Larger diaphragm area compared to seat area permits drip-tight closing without any springs. All components can be serviced while the valve is in-line.
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
- Constructed of cast iron, brass, stainless steel and Nitrile elastomer components, giving an unparalleled service life
- ¾-inch through 3-inch threaded (N.P.T. or B.S.P.); 3-inch through 6-inch flanged drilled in accordance with ASA16.1 class 125, or BSP4504
- Compatible with wide range of line fluids including air or water applications
- Reinforced diaphragms are pre-formed and stress relieved to maximize responsiveness and product life
- Can be actuated with either air or water as control fluid
