3/8 NPTF P.O. Check w/ Flush Manual Release and Low Temp Seals

NGT’s B6MFMT40 is a standard pilot operated check valve that locks pneumatic devices in position. The B6MFMT40 has 3/8 NPTF in/out ports and 1/8 NPTF pilot port, low temperature seals, and a flush manual release. The B6MFMT40 also can accommodate as low as 40 psi pilot pressure.
  • NGT’s PO checks can be used in any pneumatic application where a sudden drop in pressure would harm personnel, damage products, or otherwise hinder the manufacturing process
  • Typical applications of PO checks are clamping, work holding, & lifting equipment, doors, platforms, and material
  • Air tight design means little to no leaking. Design tightens with increased pressure
  • All aluminum o-ring grooves and faces are hard coat anodized with Teflon coating to reduce wear and increase seal life
  • Nickel plated steel piston rod for strength and corrosion resistance

Application & Function

NGT’s B6MFMT40 is a standard pilot operated check valve that locks pneumatic devices in position when a pressure drop or total loss of pressure occurs. The B6MFMT40 has 3/8 NPTF in/out ports and 1/8 NPTF pilot port, low temperature seals, and a flush manual release. The B6MFMT40 also can accommodate as low as 40 psi pilot pressure. The B6MFMT40 valve locks air in the device (such as a cylinder or gripper) until the pilot signal is energized, at which time the valve opens and evacuates the device.
