1/2" NPTF Dual Check w/ Manual Release and Low Temp Seals with Flow Controls

NGT’s D8C0MFLK18 is a dual pneumatic check valve with flow controls that maintains cylinder position by locking air in both cylinder ports. The D8C0MFLK18 has 1/2 NPTF in/out ports, standard temperature seals, and an extended manual release. The D8C0MFLK18 has flow controls to help prevent crash landings and cylinder bounce and also can accommodate as low as 20 psi pilot pressure.
  • Internal flow controls meter air out of the cylinder
  • Dual valves perform the work of two PO check valves, but in one valve package, eliminating pilot lines
  • Maintains cylinder position by locking air in cylinder
  • Cross-ported to allow the valve to open when the control valve changes direction
  • Work well in either vertical or horizontal applications ensuring precise stopping on machines with rollers or slides and eliminates some bounce
  • Improves bounce vs. a single PO check since the valve checks in both directions

Application & Function
NGT’s D8C0MFLK18 is a dual pneumatic check valve with flow controls that maintains cylinder position by locking air in both cylinder ports. This valve allows for metering airflow through the valve, slowing down how quickly the valve exhausts. This prevents crash landings and helps reduce cylinder bounce. 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 D8C0MFLK18 also works well in the vertical position by reducing bounce compared to a standard pneumatic PO check valve. The D8C0MFLK18 has 1/2 NPTF in/out ports, standard temperature seals, and an extended manual release. The D8C0MFLK18 also can accommodate as low as 20 psi pilot pressure.
