Application & Function
NGT’s B4S00-25 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 B4S00-25 has 1/4 NPTF female inlet, 1/4 NPTF male outlet, 1/8 NPTF pilot port, standard temperature seals, and no manual release. The B4S00-25 also can accommodate as low as 40 psi pilot pressure. The B4S00-25 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.
