1/4" NPTF Dual Check Valve w/ Manual Releases, Ports on Same Side and Low Temp Seals

NGT’s D4AS0MT40 is a dual pneumatic check valve that maintains cylinder position by locking air in both cylinder ports. The D4AS0MT40 has 1/4 NPTF in/out ports, low temperature seals, and an extended manual release. The D4AS0MT40 also can accommodate as low as 40 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 directionWork 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 D4AS0MT40 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 D4AS0MT40 also works well in the vertical position by reducing bounce compared to a standard pneumatic PO check valve. The D4AS0MT40 has 1/4 NPTF in/out ports, low temperature seals, and an extended manual release. The D4AS0MT40 also can accommodate as low as 40 psi pilot pressure.
