NGT’s D8CFMT40 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 D8CFMT40 also works well in the vertical position by reducing bounce compared to a standard pneumatic PO check valve. The D8CFMT40 has 1/2 NPTF in/out ports, low temperature seals, and a flush manual release. The D8CFMT40 also can accommodate as low as 40 psi pilot pressure.
