1/4" BSPP Adjustable P.O. Check Valve

NGT’s AG4M0MAD is an adjustable PO check valve that enables quicker stops if the valve is closing too slowly or drifting after changing direction on the control valve. The AG4M0MAD has 1/4 BSPP in/out ports and 10-32 pilot port, standard temperature seals, and an extended manual release.
  • 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 AG4M0MAD is an adjustable PO check valve that enables quicker stops if the valve is closing too slowly or drifting after changing direction on the control valve. Tightening the adjusting screw increases spring tension holding the valve closed, making the valve more responsive. The AG4M0MAD has 1/4 BSPP in/out ports and 10-32 pilot port, standard temperature seals, and an extended manual release. Installing a AG4M0MAD will reduce the time it takes for a PO check valve to close with a weaker pilot signal.
