NGT’s B4M00SS is a stainless steel pilot operated check valve that locks pneumatic devices in position when a pressure drop or total loss of pressure occurs. The B4M00SS has 1/4 NPTF in/out ports and 1/8 NPTF pilot port, standard temperature seals, and no manual release. The B4M00SS also can accommodate as low as 40 psi pilot pressure. The B4M00SS 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. TheB4M00SS valve's stainless steel compnents are suitable for sanitary applications requiring caustic cleaning or in corrosive environments.
