Hot Gas Bypass Regulator

SKVC-12/15/22 Hot Gas Bypass Regulator made in China. The SKVC Hot Gas Bypass Regulator is used for capacity regulation in refrigeration systems where low load conditions occur and low suction pressures and "compressor cycling" need to be avoided. Too low suction pressure also creates a vacuum in the refrigeration system, which creates a risk of moisture ingress in refrigeration systems with ported compressors.The KVC is usually installed in the bypass line between the compressor discharge and suction tubes. The SKVC opens when the outlet pressure (suction pressure) drops.

Recognition and Installation. All KV pressure regulating valves carry a label describing the function and type of valve, e.g. Hot Gas Bypass Regulator type SKVC.
The label also indicates the valve's operating range and the maximum permissible working pressure (PS/MWP). A double arrow ("+" and "-") is printed at the bottom of the label. Direction "+" (plus sign) indicates higher pressure and direction "-" (minus sign) indicates lower pressure. Without exceeding the pressure range of the valve, KV pressure regulating valves can be used for all existing refrigerants except ammonia (NH3). The valve body is stamped with the valve size, e.g. SKVC-15, and an arrow indicating the direction of flow through the valve.
