OV65 Plastic Back Flow Preventer Check Valve

Product Description


OV65 Plastic Back Flow Preventer Check Valve




OV65 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.


The average cracking (opening) pressure of most valves is between 0.25and 0.33 of a psi.


OV inserts cover a size range from 15 mm to 50 mm and provide superior flow performance (reduced headloss). 


They can  only be inserted against the direction of flow but require no retainer in the direction of flow ("snap-fit" design with flexible  tabs).





FEATURES AND BENEFITS




  1. 100% factory tested drip in operation.   


  2. Easy to insert into the application devive.


  3. Spring loaded plunger: operates in any position.


  4. Extra low headloss, extra low cracking pressure.

STRUCTURE





External o-ring seal provides sealing between the check valve  cartridge and the mating cavity into which it is inserted.





Center stem guidance optimizes the return of the  plunger head into its seat for effective sealing and to  prevent jamming 

even in hard water conditions (water  with high mineral content or sediments)





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.
