Non-Code Liquid Relief, ASME Section VIII, Air/Gas and Steam, National Board Certified, Safety and Relief Valves
Model Descriptions
Model 264: Carbon Steel (CS) housing with 316 Stainless Steel (SS) trim (nozzle and disc), SS spring. Pressure-tight cap.
Model 265: Same as model 264 except high-temperature alloy spring (temperatures to 750°F [400°C]).
Model 266: Same as model 264 except all 316 SS materials.
Model 267: Same as model 266 except high-temperature alloy spring (temperatures to 750°F [399°C]).
Model 264P: Same as model 264 with pressure-tight packed lift lever.
Model 265P: Same as model 265 with pressure-tight packed lift lever.
Model 266P: Same as model 266 with pressure-tight packed lift lever.
Model 267P: Same as model 267 with pressure-tight packed lift lever.
Features & Benefits:
- Top guided design offers high capacity with 0.110 in2 [0.710 cm2] orifice area.
- Ball pivot between disc and spring corrects misalignment and compensates for spring side thrust.
- Standard outlet with 1" Female NPT.
- Each Kunkle valve is tested and inspected for pressure setting and leakage.
Applications:
Protection of pumps, compressors, pressure vessels or systems handling corrosive fluids or vapors at high pressure and/or temperature.
Sentinel (warning) on steam equipment.
