Sanhua YCVS17-77GSHC-1 Check Valve – 7/8" ODF Solder Straight Type, 5.52 m³/h Flow, 46 Bar Pressure

Product Description

The Sanhua YCVS17-77GSHC-1 check valve is a backflow prevention valve with a high-efficiency straight piston design. With its 7/8" ODF solder connection, it integrates easily into refrigeration and air conditioning systems. It increases system safety by preventing backflow, while supporting energy efficiency with low pressure loss.

Key Features

• Prevents Backflow: Ensures that refrigerants flow only in the correct direction.
• Damping Spring Design: Contains a spring-loaded piston that withstands pressure pulsations and dampens vibration.
• Installation Flexibility: The straightway type is preferred for vertical flow; it can also be installed at near-horizontal angles.
• Wide Refrigerant Compatibility: Fully compatible with HCFC, HFC and HFO refrigerants (R22, R134a, R404A, R407C, R410A, R507A, R513A, R449A, etc.).
• Low Pressure Drop: Provides efficient flow and reduces the load on the system.
