Application & Function

NGT’s BG4M0MAD is an adjustable PO check valve that enables quicker stops if the valve is closing too slowly or drifting after changing direction on the control valve. Tightening the adjusting screw increases spring tension holding the valve closed, making the valve more responsive. The BG4M0MAD has 1/4 BSPP in/out ports and 1/4 BSPP pilot port, standard temperature seals, and an extended manual release. Installing a BG4M0MAD will reduce the time it takes for a PO check valve to close with a weaker pilot signal.
