Features & Benefits:
- O-ring seats available for exceptional leak-free performance, reduced maintenance cost, multiple cycles with tight shutoff, improved seating integrity.
- Wide hex on valve nozzle provides wrenching service clearance for easy installation.
- Dual control rings offer easy adjustability for precise opening with minimum preopen or simmer and exact blowdown control.
- Pivot between disc and spring corrects misalignment and compensates for spring side thrust.
- Grooved piston model disc reduces sliding area and friction.
- Each Kunkle valve is tested and inspected for pressure setting and leakage.
Applications:
Steam Boilers and Generators.
Air/Gas Compressors - reciprocating or rotary - portable or stationary, intercoolers and aftercoolers.
Pressure Vessels - containing steam, air or non-hazardous gas. Including tanks, receivers, sterilizers and autoclaves.
Pressure Reducing Stations - protection of the discharge or low pressure side of system.
