148B5536

The 148B5536 check valve belongs to the CHV Check Valves series produced by Danfoss for hydraulic automation circuits where reverse flow must be blocked. It connects to pipework through a 32 mm butt weld end that complies with EN 10220, so the valve can be integrated directly into standard metric tubing runs without threaded adapters. An angleway flow path guides the medium through a 90-degree turn to fit compact line layouts while safeguarding sealing faces. The kv value of 30 m³/h defines the expected volumetric capacity at 1 bar differential, helping designers size pumps and actuators accurately. An opening differential of 0.04 bar allows the disc to lift with minimal upstream pressure, reducing energy loss and maintaining rapid response during load changes.

The valve housing is built from special cold-resistant steel, which permits operation down to −60 °C in refrigeration or offshore hydraulic service without embrittlement. A maximum temperature rating of 150 °C extends usability to hot oil circuits, and a maximum working pressure of 52 bar lets the component withstand high-pressure supply lines common in industrial machinery. The internal cone closes against a metallic stop, so seating travel is precisely limited to protect the sealing edge from overcompression. Stainless-steel bolts secure the body sections, offering corrosion resistance in humid or chemically aggressive environments and facilitating repeatable torque during maintenance.
