1/4" NPTF Swivel-Mounted PO Check Valve w/ Flow Controls - 1/8" Outlet and flush manual relase

NGT’s B4SFMFL-12 is a swivel-mounted pilot operated check valve with flow controls that prevents crash landings and cylinder bounce and also mounts directly to a pneumatic cylinder. The B4SFMFL-12 has 1/4 NPTF female inlet, 1/8 NPTF male outlet, 1/8 NPTF pilot port, standard temperature seals, and a flush manual release. The B4SFMFL-12 also can accommodate as low as 40 psi pilot pressure.
  • Male outlet ports on swivel valves enable direct mounting to cylinders
  • 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 B4SFMFL-12 is a swivel-mounted pilot operated check valve with flow controls. The male outlet allows the valve to mount directly to a cylinder or other pneumatic device. The male outlet of the valve swivels, allowing the valve to rotate as needed around the cylinder. The B4SFMFL-12 has 1/4 NPTF female inlet, 1/8 NPTF male outlet, 1/8 NPTF pilot port, standard temperature seals, and a flush manual release. The B4SFMFL-12 also can accommodate as low as 40 psi pilot pressure. The B4SFMFL-12 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. This valve has flow controls, allowing for metering airflow through the valve and slowing down how quickly the valve exhausts. This prevents crash landings and helps reduce cylinder bounce. Note that restricting airflow through the valve will also slow down systems. NGT’s flow control valves have an adjusting screw that reduces how far the poppet can lift up off of the seat. This valve is also available in high/low temperature versions.
