Description

Documentation
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.
Specifications
Applications: Multi-stage high pressure compressors, intercoolers and aftercoolers. High pressure receivers and storage bottles. Thermal expansion relief.
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.)
