NGT’s B4M00SSV 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 B4M00SSV has 1/4 NPTF in/out ports and 1/8 NPTF pilot port, high temperature seals, and no manual release. The B4M00SSV also can accommodate as low as 40 psi pilot pressure. The B4M00SSV 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. TheB4M00SSV valve's stainless steel compnents are suitable for sanitary applications requiring caustic cleaning or in corrosive environments.
