NGT’s D6CFM is a dual pneumatic check valve that maintains cylinder position by locking air in both cylinder ports. NGT’s dual pneumatic locking valves perform the work of two PO check valves but in one valve package. Dual pneumatic check valves work well in horizontal applications by ensuring precise stopping. The D6CFM also works well in the vertical position by reducing bounce compared to a standard pneumatic PO check valve. The D6CFM has 3/8 NPTF in/out ports, standard temperature seals, and a flush manual release. The D6CFM also can accommodate as low as 40 psi pilot pressure.
