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

NGT’s B4SFM-12 is a swivel-mounted pilot operated check valve that locks pneumatic devices in position and mounts directly to a pneumatic cylinder. The B4SFM-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 B4SFM-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 B4SFM-12 is a swivel-mounted pilot operated check valve that locks pneumatic devices in position when a pressure drop or total loss of pressure occurs. The male outlet allows the valve to mount directly to a cylinder or other pneumatic device. The valve's male outlet port swivels, allowing the valve to rotate as needed around the cylinder. The B4SFM-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 B4SFM-12 also can accommodate as low as 40 psi pilot pressure. The B4SFM-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 is also available in high/low temperature versions and can be configured as adjustable and flow control models.
