SINGLE CHECK VALVE OD12 - OD12 BLACK - HCVU1212B

The HCVU1212B is a Fluid-fit non-return check valve with sockets for tube outside diameters of Ø12 mm and Ø12 mm. It allows flow in one direction and restricts reverse flow. Install it in the flow direction specified by the manufacturer.

The body is made from acetal plastic POM (polyoxymethylene), with socket seals made from EPDM (ethylene propylene diene monomer rubber). The push-to-connect arrangement requires tubing of the correct outside diameter with a clean, square-cut end. The cracking pressure is 0.02 to 0.04 bar differential pressure. This valve is not a pressure regulator and does not replace a specifically certified backflow-protection device where one is required.

The temperature range is +1°C to +65°C. The series rating table allows up to 10 bar at +25°C and up to 7 bar at +65°C, while the tubing and fluid limits must also be observed. Fully depressurise before disconnecting or servicing; closing the supply alone does not remove trapped pressure. Subject to compatibility checks, typical applications include:

• Water treatment systems
• Auxiliary low-pressure circuits in desalination systems
• Food and beverage equipment with a suitable, compatible medium
