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. Features and Benefits  Zero leak at low and high pressure and temperature.Generous flow structure promise the lowest headloss.Compact, easy installation, 8mm-50mm diameter to meet all the system.No thread connection to avoid potential leakage    WHY CHOOSE US? 1)XHnotion offer one stop solution. Over 5000 items for you to save efforts and costs.   2)We have molds workshop, die-casting workshop, CNC workshop, plastic injection workshop to make sure each part exactly as the drawing and good function.   3) We will answer within 24 hours.   4) Whatever quantity you are requesting, we always offer you the best quality.   5)3D drawing, cad drawing service for custom fittings, hose, valve, cylinder   Our Factory                                                                                  Our Workshop     Our Package                                                                                Our Warehouse   XHnotion, is a leading manufacturer of pneumatic components and flow valve in China.
