NGT’s B121FMK18T40 is a standard pilot operated check valve that locks pneumatic devices in position when a pressure drop or total loss of pressure occurs. The B121FMK18T40 has 3/4 NPTF in/out ports and 1/4 NPTF pilot port, low temperature seals, and a flush manual release. The B121FMK18T40 also can accommodate as low as 25 psi pilot pressure. The B121FMK18T40 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.
