MODELS 215V/337 VACUUM RELIEF AND SAFETY VALVES

Features

• Llarge nozzle design provides high capacity.
• Flat bronze valve seats are lapped for optimum performance.
• Warn ring offers easy adjustability for precise opening with minimum pre-open or simmer.
• Pivot between disc and spring corrects misalignment and compensates for spring side thrust.
• Model 215V has seal cap for vacuum service.
• Model 337 has ‘lift-pin’ lift device for easy manual testing.
• Bronze nozzle and disc as standard. optional SS trim available.
• Each valve tested and inspected for pressure setting and leakage.
