Model POSR-1 Pressure Reducing Regulator Pilot Operated

The Model POSR-1 is a pilot operated regulator primarilyfor use with steam. The external pilot valve is suppliedfrom a main valve body tapped connection. Sizes are 1/2",3/4" and 1" (DN15, 20 and 25). Handles pressure dropsup to 200 psi (13.8 Bar) with adjustable outlet pressures between 5 and 150 psig (.34 and 10.3 Barg). It is also availablewithout the pilot as a pressure loaded regulator.

Applications
Primarily used in steam heating in hospitals, hotels, motels,office buildings, factories, apartment buildings, warehouses, shopping malls, green houses, university buildings, sport complexes and airports.Used on stills, cookers, dryers, presses, pasteurizers, purifiers, sterilisers, mangles, washers, rendering machines,bleachers, vulcanisers, oil heaters, moulding machines,steam jacketed equipment, kilns, retorts, heat exchangers, paper and board machines, steam driven auxiliaries,blowers, pumps and centrifuges.

  • Hardened Trim: 416 SST hardened pilot and main valve trim for long life.
  • Bellows Seal: The pilot uses a bellows as a frictionless seal for the pilot valve plug. It was in corporated to ensure that the pilot maintains its sensitivity and smooth operation in older steam systems that are chemically treated and systems that are used intermittently.
  • High Sensitivity: Four pilot range springs provide high sensitivity and contribute to the valveā€™s
    excellent stability.
