Model 200 Pressure Limiting Valve

Model 200 "Gauge Minder" features a pressure limiting valve that blocks off excess pressure to the instrument, preventing calibration failure, internal damage, and “blow-out” from over-ranging - a principal cause of instrument failure. 

Model 200 is supplied with a set of range springs designed to set the shutoff pressure point at any pressure from 50 to 5,000 psi. 

The automatic shutoff valve is positive on closing and is non-chattering. 

Once closed, pressure need only be reduced approximately 10% of set pressure to re-open the valve. 

The accuracy of the instrument used with the Model 200 is in no way affected up to the set point of the pressure shutoff.
