MODEL 200Pressure limiting valve（200系列压力限制阀）
Protection of Pressure Gauges and Transmitters Components from Over Pressure
（保护压力表或变送器；避免过压损坏）
The Model 200 “Gauge Minder” features a pressure limiting valve that blocks off excess
to the instrument, preventing calibration failure, internal damage, and “blowout” from
over-ranging - a principal cause of instrument failure.
The Model 200 is supplied with a set of (3) range springs designed to set the shutoff point at
any pressure from 50 PSI (3.4 bar) to 5000 PSI (340 bar). The automatic shutoff valve is positive
closing and is non-chattering. Once closed, pressure need only be reduced approximately 10% of
pressure to re-open the valve. No external reset is required. The accuracy of the instrument used
with the Model 200 is in no way affected up to the set point of the pressure shutoff.
