Compact design requires minimum installation space. Angle lapped seat provides tight shut-off.

ASME Section VIII, Air/Gas Cryogenic, ‘UV’ National Board Certified Safety Valves.

Unique three-piece disc assembly (with seat/seal) offers superior ‘leak-free’ performance over the entire pressure/temperature operating range. Control ring offers precise adjustment of blowdown. Pivot betwee disc and spring corrects for all misalignment and compensates for spring side thrust. Every valve 100% tested/inspected for set pressure, blowdown and leakage. All adjustments are factory sealed to prevent tampering and disassembly.

ASME Section VIII, Air/Gas Vacuum, ‘UV’ National Board Certified Safety Valves.

Large nozzle design provides high capacity. Flat bronze valve seats are lapped for optimum performance. Warn ring offers easy adjustablility for precise opening with minimum pre-open or simmer and exact blowdown control. Pivot between disc and spring corrects misalignment and compensates for spring side thrust.

Relief Valves, ASME Section VIII, Gas, ‘UV’ National Board Certified.

Lightweight aluminum construction. Resistant to environmental and internal corrosion. Aluminum parts are anodized for corrosion resistance. Model 230 is direct spring-loaded design with synthetic disc insert. Model 330 series incorporates a differential mechanism which maintains a predetermined seat-contact load. The full spring load is never imparted to synthetic disc insert (models 330, 330S, and 333S only). Seat tightness increases to a maximum as inlet pressure approaches the opening pressure.

Non-Code Liquid Relief, ASME Section VIII, Air/Gas and Steam, National Board Certified.

Top-guided design offers high capacity with .110 in 2 orifice area. Ball bearing pivot between disc and spring corrects misalignment and compensates for spring side thrust. Every valve 100% tested/inspected for pressure setting and leakage. Standard outlet with 1-inch Female NPT.

Steel yoke incorporates a cover-shield for guiding surfaces and provides for fully exposed spring. Seats lapped to optical flatness for tight shut-off. Dual control rings offer easy adjustability for precision opening with minimum pre-open or simmer and exact blowdown control. Every valve 100% tested/inspected for pressure setting, blowdown and leakage. All adjustments are factory sealed to prevent tampering or disassembly.

ASME Section IV, Low Pressure Hot Water Boilers, ‘HV’, National Board Certified.

Extra heavy construction provides long life. Top guided disc assembly incorporates resilient seal in seating area. An isolating diaphragm protects working parts from corrosion caused by discharged liquid Pivot between disc and spring corrects for misalignment and compensates for spring side thrust. These safety relief valves serve the dual purpose of relieving (1) over pressure created by thermal expansion under normal ‘on and off’ firing conditions and (2) over pressure in the form of water or steam created in over-firing due to failure of electrical or other controls.
