Model POSR-2 Pressure Reducing Regulator Pilot Operated

The Model POSR-2 is a pilot operated regulator primarily for use with steam. The external pilot valve is suppliedfrom a main valve body tapped connection. Sizes are 1/2",3/4", 1", 1-1/4", 1-1/2", 2", 3" and 4" (DN15, 20, 25, 32,40, 50, 80 and 100). Handles pressure drops up to 200 psi (13.8 Bar) with adjustable outlet pressures between 5and 150 psig (.34 and 10.3 Barg).

The POSR-2 is primarily used in steam distribution systems for the first pressure letdown to comply with commercial codes. Used 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: Hardened pilot and main valve trim for long life.
  • Bellows Seal: The pilot uses a bellows as a fric tionless seal for the pilot valve plug. It was incorporated to insure that the pilot maintains its sensitivity and smooth operation in older steam systems that are chemically treated and systems that are used in ter mit tent ly. Prevents common “sticking” of pilot valve.
  • High Sensitivity: Four pilot range springs provide high sensitivity and con trib ute to the valve’s excellent stability.
