1. Description:
Check valve, also known as non-return valve, back pressure valve, one-way valve. This kind of valve is automatically opened and closed by the force generated by the flow of pipeline mediation itself, it is a kind of automatic valve. Used in household RO water purifiers, between RO membrane outlet and pure water pressure barrel (water tank), that make the pure water flow only from RO membrane to water tank, and can’t flow back, the water purifier stops working when water tank is full. The check valve is the first component that pure water contacts after being produced, its role is to prevent backflow of the pure water from leading to waste of resources.
2. Specification:
Wisnex series check valve, unique structure,with excellent anti-blocking, anti-leakage performance, widely applicable to all types of high-grade water dispenser, RO drinking system, pipeline machines, water purifiers, coffee machines and other household appliances.
To resolve the issues of low upstream pressure of at some areas, WISNEX invented and developed the models of LARGE FLOW check valve, with the patent for invention No.2013100385724, 2013200559539. Through our extensive testing, It has good performance even at low water pressure situation.
