The range of pressure and temperature regulating valves have a lot of different functions in the commercial refrigeration and airconditioning plant. Capacity regulation, crankcase pressure regulation, receiver pressure regulation, evaporation pressure regulation and condensing pressure regulation.The regulators are delivered with flare or solder connection. Where neccesary the regulators are delivered with schrader valve.

KVP evaporator pressure regulator, suction line
KVP evaporator pressure regulators are mounted in the suction line of refrigeration and air conditioning systems. They are used to maintain a constant pressure corresponding to a constant temperature on the evaporator. They also protect against too low an evaporating pressure by throttling down when the pressure falls below the set value.

KVR condensing pressure regulator
KVR condensing pressure regulators can be mounted in either the gas or liquid side of the condenser in refrigeration and air conditioning systems. They are used to maintain a constant and sufficiently high condensing pressure with systems using air-cooled condensers. KVR condensing pressure regulators can also be used with differential pressure valves type NRD or receiver pressure regulators type KVD to assure that adequate pressure is maintained on the receiver.

KVR condensing pressure regulator
KVC hot gas bypass regulators are used to adapt compressor capacity to actual evaporator load by supplying a replacement capacity in the form of hot/cool gas. They are installed in a bypass line between the high and low-pressure sides of the refrigeration system and are designed for direct gas injection into the suction line.

CPCE hot gas bypass regulator (with LG)
CPCE hot gas bypass regulators are used to adapt compressor capacity to actual evaporator load. CPCE hot gas bypasses are installed in a bypass line between the high and low pressure sides of the refrigeration system and are designed for hot gas injection into the evaporator just after the expansion valve. Liquid-gas mixer LG can be used at the point of injection to assure a proper mixture.

KVL crankcase pressure regulator, suction line
KVL crankcase pressure regulators are installed in the suction line of refrigeration systems. They are used to protect the compressor motor against overload experienced during startup after long off periods or just after defrost periods.
