Pressure Limiting Valve

  • Pressure Limiting Valve prevents instrument over-range
  • Adjustable needle valve dampens pulsation
  • Use with all types of pressure instruments
  • Choices of aluminum, brass, or stainless steel body material
  • Can be mounted in any position

The 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.

The Model 200 is supplied with a set of range springs designed to set the shutoff pressure point at any pressure from 50 to 5000 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.

The Model 200 also features an adjustable needle valve designed to dampen system pulsation reducing instrument oscillation, improving readability, and extending instrument life without the addition of a snubber. Instrument reliability is improved and the cost to repair, re-calibrate, or replace the instrument is lowered.

The Model 200 is available in Aluminum, Brass, or 316 Stainless Steel with 1/4” FNPT connections for 5000 PSI working pressure and in Brass or 316 Stainless Steel with 1/2” FNPT connections for 10,000 PSI working pressure. Buna N O-rings and Teflon backup rings are standard. Optional seal materials include Viton, Neoprene, and Ethylene Propylene.
