Superior offers the most complete range of refrigeration relief valves in the industry with both low and high pressure ratings. All valves have been designed, constructed and rated in accordance with ANSI/ASHRAE 15 - 1994 standard safety code for mechanical refrigeration. Each valve is stamped UV/N. to indicate National Board certifications as to capacities. These pressure-relief valves are all Teflon seated, permitting their use in applications of either high or low temperatures where the conventional rubber seated valves are often completely unsatisfactory.
  • Stainless steel spring material construction
  • Initial leak set pressure plus/minus 3%
  • Reset at 80% of set pressure

Type LAC head pressure control valves have a brass body with copper connections. These valves are nonadjustable. They perform the function of limiting flow of refrigerant from the condenser and at the same time regulate the flow of hot gas around the condenser to the receiver during low ambient conditions, so as to keep the refrigerant in the liquid line at proper pressure. Each valve is factory tested to ensure positive leak-free performance.
  • Metal to metal seating material
  • Knife edge joint
  • Less strainer

Crankcase Pressure Regulating Valves are designed to prevent overloading of the compressor motor by limiting the crankcase pressure to a predetermined maximum value during and after a defrost cycle or a normal shutdown period. These valves automatically throttle the vapour flow from the evaporator until the compressor can handle the load. Parker Sporlan manufactures five adjustable direct acting models CRO-4 all models respond only to their outlet pressure and modulate to prevent the suction pressure at the compressor from rising above the valve setting. Since these valves are adjustable, the setting may be altered to suit the specific system requirements.

Parker has engineered a full line of pressure regulating valves to control evaporator pressure, crankcase pressure, head pressure, and discharge bypass. A consistent evaporating temperature is maintained at the valve setting as evaporator loads decrease. When the evaporator load increases, the ORIT valve opens on a rise of inlet pressure above its setting.
