About Two way check valve coupling [2011-01-06]

Two way hydraulic check valve coupling - These are designed for connecting hydraulic lines. They are also extensively used where a variety of other fluids are involved. They are made to withstand pressure from 800 to 10000 PSI depending upon size and material. They contain valves in both the coupler and adaptor to prevent loss of fluid when the parts are disconnected.
 
Straight Through Couplings. - These are designed without valves to provide the least resistance to fluid flow. Therefore, they require manual check valves in both lines if fluid loss is to be prevented when the couplings are disconnected. Straight thru couplings provide for fast simple connection to any type of system.

Hydraulic Coupler bodies of this design are manufactured in brass, steel, stainless steel. The wide range of sizes from 1/8" to 3" allows the employment in fields ranging from instrumentation to steel mills.
