GAR Check valves type CHV has been designed to be used on refrigeration and air conditioning system, on liquid and suction line. Their installation avoid the risk of flow inversion.

Materials
Brass CW617N Obturator CW614N O ring HNBR

Installation
They can be mounted also in a vertical or horizontal position. The system must be clean before the assembly because they are sensitive to impurities. We recommend to use a soldering league with low fusion point during the soldering process of the check valve CHV on the system. During this process do not point the flame directly towards the body to avoid compromising the seal of the internal gaskets

Operating conditions
TS -40°C + 150°C PS 30 bar
Refrigerant fluids: HFC, HFO, blends Available on demand for HC e CO2

Emkarate® RL 170H is a cSt 170 synthetic polyol ester (POE) lubricant formulated specifically for use in refrigeration and air-conditioning compressors using HFC refrigerants. This product provides effective wear protection for steel and aluminum surfaces for increased system life and improved efficiency and is suitable for both initial fill and service fill. The combination of low temperature characteristics and unparalleled chemical and thermal stability enable the use of Emkarate® RL 170H over a wide operating temperature range.
