Model 200 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 principle cause of instrument failure. Valve dampener is supplied with a set of range springs designed to set the shutoff pressure point at any pressure from 50 to 5000 PSIG. 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. Accuracy of the instrument used with Model 200 is in no way affected up to the set point of the pressure shutoff.

Model 200 also features an adjustable needle valve designed to dampen system pulsation reducing instrument oscillation, improving readability while
