Non -Return / check Valve

 

 

 

 

Check valves (RF)are automated shut off  Flanged valves with either stainless steel, brass,or cast iron plate or tongue inside.The hydraulic pressure of these particular hydraulic or oil check valve normally varies from 150psi-1500psi. Hydraulic and oil check valves are automatic valves to determine the outflow and inflow of particle like hydraulic fluids, oil liquids, petroleum substance, water and chemical products.t

The use of hydraulic oil check valves .

The use of check valves helps to stop the release of air, liquid and solid particles to the environment after operation.It automatically shut off the valve when the sucking pressure is minimized.


They are used in connection with oil or hydraulic hoses and pipe both during onshore and offshore services.
. Not all hydraulic oil check valves are flanged ,some are formed to have a female or male threaded part at the both end. And some can also have a socket end on both sides.
The use of the threaded end is to allow for an easy reconnection with a hose or pipe with an Npt threading which could be used in connection with a weco union or hydraulic crimp fittings .
