Cartridge Check Valves
Cartridge 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.
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.
Features and Benefits
Zero leak at low and high pressure and temperature.
Generous flow structure promise the lowest headloss.
Compact, easy installation, 8mm-28mm diameter to meet all the system.
No thread connection to avoid potential leakage
