PBP Series Back-Pressure Pilots

PBP Pilot

The PBP-Back Pressure Pilot, used with the HD regulator, maintains upstream pressure in steam systems. These regulators are commonly used to supply flash steam to low pressure mains

Features
  • The PBP-Pilot can maintain upstream pressure to ±1 PSIG
  • Choices of three overlapping pressure ranges
  • Pilot is easily installed using four bolts. No tubing connection required
  • Full port strainer and blowdown valve on pilot adapter for protection of pilot from dirt and scale
  • Solid floating (no penetration hole) pilot diaphragm resists failure
  • Watson McDaniel's pilots can be used with other manufacturers’ regulators


Back Pressure

The PBP Back-Pressure Pilots are used with HD Regulators to maintain upstream pressures in steam systems. When the ups tream pressure reaches the pilot set point , the regulator opens. The HD Regulator with a PBP Back-Pressure Pilot is commonly used to supply steam to low-pressure mains. The PBP Back-Pressure Pilot maintains a constant back-pressure on the inlet side of the regulator. Should not be used in place of a safety relief valve.
