EVR/EVRH/EVRC – Solenoid valve

EVR / EVRH solenoid valves are direct or servo-operated solenoid valves for liquid, suction and hot gas lines. They are suitable for condensing units and power packs in all refrigeration, freezing and air conditioning applications and are compatible with fluorinated refrigerants R22/R407C, R404A/R507, R410A, R134a and R407C. Versions are also available for high pressure refrigerants such as R410A and R744 (CO2) with a max working pressure of 45 Bar. The valves can be delivered as normally open or normally closed valves and with or without manual operation.

EVR valves are available with flare, solder or flange connections. EVRC is a servo operated solenoid valve for use in liquid lines in refrigeration plant. EVRC allows flow in both directions and can therefore be used in liquid lines in refrigeration plant with hot gas or gas defrost. During the refrigeration period EVRC works as a normal solenoid valve, while during the defrost it allows the condensed liquid to return to the liquid manifold.

KPU – Pressure switch

The KPU pressure switches are designed for use in refrigeration and air-conditioning systems to protect the systems from excessively low suction pressure or too high discharge pressure. They can also be applied to start and stop compressors and the fans of air-cooled condensers. The KPU pressure switches , in single and dual versions cover a comprehensive range of applications, and are designed for use with HCFC and non-flammable HFC refrigerants.

KVR / NRD – Condensing pressure regulator / Differential pressure valve

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 valve types NRD or KVD to assure that adequate pressure is maintained on the receiver.

MP – Differential pressure switch

MP 54 and MP 55 oil differential pressure switches are used as safety switches to protect refrigeration compressors against low lubricating oil pressure.

MP 55A is designed for use in refrigerating systems with R717 (ammonia), and can also be used in systems with HCFC and non-flammable HFC refrigerants. MP 54 has a fixed differential pressure setting. It also incorporates a thermal time relay with a fixed release time setting. MP 55 and MP 55A have adjustable differential pressure and are available both with and without thermal time relay.

KVP – Evaporator pressure regulator

KVP evaporating 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.

KVL – Crankcase pressure regulator

KVL crankcase pressure regulators valves are installed in the suction line ahead of the compressor. KVL protects the compressor motor against overload during start-up after long standstill periods or after defrost periods (high pressure in evaporator).

KVP - Evaporator pressure regulatorKVL – Crankcase pressure regulator

KVC – Hot gas bypass regulator

KVC are hot gas bypass regulators used for the adaption of the compressor capacity to the actual evaporator load. Placed in a bypass between high and low pressure sides of the refrigeration system, KVC imposes a lower limit on the compressor suction pressure by supplying the low pressure side with replacement capacity in the form of hot gas/cool gas from the high pressure side. KVC is for HCFC, HFC and HC refrigerants.

KVC – Hot gas bypass regulator

CPCE – Hot gas bypass regulator

CPCE hot gas bypass regulators adapt compressor capacity to actual evaporator load, and are designed for installation in a bypass line between the low and high pressure sides of the refrigeration system, for hot gas injection between evaporator and thermo-static expansion valve. CPCE is for HCFC, HFC and HC refrigerants. Injection is through an LG liquid-gas mixer.

WVFX/WVO/WVS – Pressure operated water valve

WVFX, WVO and WVS pressure operated water valves are used to regulate the flow of water in HCFC, HFC and HC refrigeration plant with water-cooled condensers in order to ensure constant proportional regulation of condensing pressure. The water valve modulates the water flow to maintain the condensing pressure at a constant level during operation. When the refrigeration plant is stopped, the cooling water flow is shut off automatically. Media: fresh water and neutral brine. For use with aggressive media such as sea water, WVFX 15, WVFX 20 and WVFX 25 are available in stainless steel versions.
