Sanhua YCVS20-77GSHC-1 Check Valve – 7/8" L-Type, 13.2 m³/h Flow, 46 Bar Maximum Pressure

Product Description

The Sanhua YCVS20-77GSHC-1 L-type check valve is a high-performance piston-type check valve designed for commercial refrigeration systems and industrial air conditioning applications. With a 7/8 inch ODF connection size, this model has a maximum working pressure of 46 bar (4.6 MPa) and a Kv flow capacity of 13.2 m³/h.

This check valve was developed to prevent backflow and allow flow in one direction only. Thanks to the damping spring in its internal structure, it can be safely installed at points subject to pressure pulsation. It also offers safe use over a wide temperature range from -50°C to +140°C.
