NGT’s BG4MFMFL pilot operated check valve with flow controls allows for metering airflow through the valve, slowing down how quickly the valve exhausts. This prevents crash landings and helps reduce cylinder bounce. Note that restricting airflow through the valve will also slow down systems. NGT’s flow control valves have an adjusting screw that reduces how far the poppet can lift up off of the seat. The BG4MFMFL has 1/4 BSPP ports and 1/4 BSPP pilot port. The BG4MFMFL has standard temperature seals and a flush manual release. Installing BG4MFMFL flow control valves provides a more affordable solution than a using a separate flow control valve while also reducing leak paths and simplifying piping. The BG4MFMFL also can accommodate as low as 40 psi pilot pressure.
