NGT’s D3000 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 D3000 also works well in the vertical position by reducing bounce compared to a standard pneumatic PO check valve. The D3000 has 10-32 in/out ports, standard temperature seals, and no manual release. The D3000 also can accommodate as low as 25 psi pilot pressure.
