ALADCO 612502BSPP
ALADCO (612502BSPP) Dual Check Valve, Internal Pilot Operated w/ Flush Override, 1/4" BSPP Ports, 15-150 PSI, Viton Seals
Aladco® double check valves use two check valves in the same body. Double check valves trap air in both sides of a cylinder or actuator and the pilot operation automatically pilots the opposite check allowing the cylinder to move. Our patented manual override relieves the air on both sides of the cylinder or actuator. One manual override button creates a better-controlled and safer release of air because it relieves air from both sides of the cylinder simultaneously.
