Product Description

DN20 Water Meter Plastic Back Flow Preventer Check Valve

DN20 CHECK VALVE

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.

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.

DN cylindrical cartridges cover a size range from 8 mm to 25 mm and offer the easiest assembly:

they can be inserted into the application device both in the direction of flow and against the direction of flow.

They need to be held into place (retention) in both directions.

Standard XHnotion check valves are spring loaded to ensure reliable operation in any position of installation and fast

positive sealing even in low backpressure conditions.
