in reversed free flow (Fig. a), the internal drain type is normally used.  

When the back pressure is applied to the outlet 

side P1 (Fig. b), be sure to use the external drain type. 

until operated by pilot pressure to a llow free reverse flow.  

The specified cracking pressure is required to open 

the valve to allow free flow direction.

That depends on the pressure of the inlet side P2 in the reversed free flow. 

This value can be determined from the characteristics chart. 

These check valves allow flow in one direction 

When the outlet side P1 is directly connected to the tank
