Kunkle Pressure Relief Valves, Direct Spring Process Valves, Thermal/Threaded Valves, Kunkle Safety and Relief Products Models 230, 330, 330S and 333S 

ASME Section VIII, Gas, “UV” National Board Certified. PED certified for non-hazardous gas.

Model Descriptions
Model 230: 1/4" Male NPT - 300/1500 psig.
Model 330: 1/4" Male NPT - 1000/5500 psig. Aluminum housing, SS trim (seat and disc with synthetic insert). Sidewall discharge.
Model 330S: Same as model 330 except SS body suitable for 1000/6500 psig.
Model 333S: Same as model 330S except 1/2" Female NPT side outlet. Pressure-tight cap.

Features & Benefits:

  • Lightweight aluminum construction. Resistant to environmental and internal corrosion.
  • Model 230 (non-code) 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.
  • Each Kunkle valve is tested and inspected for pressure setting and leakage.

Pressure and Temperature Limits
Model 230: 300 psig to 1500 psig [20.6 barg to 103.4 barg]; -20°F to 185°F [28.9°C to 85°C]
Model 330: 1000 psig to 5500 psig [68.9 barg to 379.2 barg]; -20°F to 185°F [28.9°C to 85°C]
Model 330S: 1000 psig to 6500 psig [68.9 barg to 448.1 barg]; -20°F to 185°F [28.9°C to 85°C]
Model 333S: 1000 psig to 6500 psig [68.9 barg to 448.1 barg]; -20°F to 185°F [28.9°C to 85°C]

Maximum back pressure 100 psig (Back pressure reduces set pressure on a one to one basis and reduces capacity. Back pressure in excess of 10% of set pressure is not recommended.)
