If you detect internal leakage (bypass) when the valve is de-energized or if the valve fails to open/close completely despite power being supplied to the coil

By connecting the high-pressure port upstream and the low-pressure port downstream of the filter

For use with Q5001 Linkage

maintaining strict operational tolerances

it offers a full 0-100% angle of rotation adjustment range for connected actuators

Antunes Controls 804111702 Pressure Control Els PW 17895 If you detect internal leakageThe Antunes Controls 804111702, specifically the Model HLGP A, is a dual function high and low gas pressure switch engineered for precision monitoring in industrial burner systems. This manual reset pressure control features a dual SPDT circuit configuration, ensuring fail safe operation by breaking the electrical circuit if gas pressure exceeds or falls below calibrated setpoints. The high pressure side offers an adjustable range of 5 28" W. C.,
