Cartridge Check ValvesCartridge check valves (also called non-return valves) are designed for simple installation and offer outstanding performance inside mating housing. They are valves which only allows water to flow in one direction and prevents backflow.
XHnotion cartridge check valves are not only for water, also for air now. Applications include faucets, showers, valves and heating systems for residential or commercial installations, as well as pumps,
All the models are 100% tested during production for drip tight operation. Maximum temperature and pressure rating is for most models 200F(90C)/230psi. The average cracking (opening) pressure of most valves is between 0.25and 0.33 of a psi.
Working Principles
In static conditions (no flow)
The check valve is normally closed. The spring tension forces the plunger into its
seat keeping the check valve closed.
In dynamic conditions (flow)
The water pressure exceeds the spring tension. The plunger is lifted off its seat
allowing water to flow through the valve.
In backflow conditions (reversed flow)
If the pressure downstream of the valve increases (back pressure conditions) or if
the system pressure upstream of the valve decreases (backsiphonage conditions)
causing the flow to reverse direction, the spring-loaded plunger closes and
prevents backflow.
