PP Pilot

The "PP" Pressure Pilot is used with the HD Regulator to control steam pressure in steam mains or for process equipment. Pilot operated regulators will maintain constant downstream pressure even when the inlet pressure to the valve fluctuates or steam usage varies.

The PP Pilot can maintain downstream pressure to ± 1 PSIG

Model: PP Pilot
Body & Cover Material: Ductile Iron or Cast Steel
Max Inlet Pressure:  300 PSIG
Reduced Outlet Pressure Range: 3-200 PSIG
Minimum Inlet Pressure:
  15 PSIG (w/ Std Main Valve)
  5 PSIG (w/ Low Pressure Main Valve)
Accuracy:  ± 1 PSIG
     

PP5 Pilot

The "PP5" Pressure Pilot is used with the HD Regulator to control steam pressure in steam mains or for process equipment. Pilot operated regulators will maintain constant downstream pressure even when the inlet pressure to the valve fluctuates or steam usage varies.

The P5 Pilot can maintain downstream pressure to ± 0.5 PSIG

Model: PP5 Pilot
Body & Cover Material: Ductile Iron or Cast Steel
Max Inlet Pressure:  300 PSIG
Reduced Outlet Pressure Range: 1-25 PSIG
Minimum Inlet Pressure:
  15 PSIG (w/ Std Main Valve)
  5 PSIG (w/ Low Pressure Main Valve)
Accuracy:  ± 0.5 PSIG
     

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.

The PBP Pilot can maintain downstream pressure to ± 1 PSIG

Model: PBP Pilot
Body & Cover Material: Ductile Iron
Max Inlet Pressure:  300 PSIG
Back Pressure Range: 10-200 PSIG
Minimum Inlet Pressure:
  15 PSIG (w/ Std Main Valve)
  5 PSIG (w/ Low Pressure Main Valve)
Accuracy:  ± 1 PSIG
     

PT Pilot

The “PT” Temperature Pilot is used with the HD regulator to control temperature in various processes and systems. Some examples are: Oil Heaters, Ovens, Process heaters, Vats, Dryers and Jacketed Kettles.

Note: The Low Pressure Temperature Pilot must be used in conjunction with a low pressure main valve for applications where inlet steam pressure is less than 15 PSIG. SPECIFY WHEN ORDERING.

CATALOG SPEC SHEET(S)

Model: PT Pilot
Body Material: Ductile Iron / Cast Steel
Max Inlet Pressure:  300 PSIG
Temperature Control Range: 60-260 °F
Minimum Inlet Pressure:
  15 PSIG (w/ Std Main Valve)
  5 PSIG (w/ Low Pressure Main Valve)
     

PA Pilot

The “PA” Air Pilot is used with the HD Regulator to control steam pressure on steam mains and process equipment. The “PA” Air Pilot can also be used in conjunction with the PTL or PTR pneumatic temperature controllers for controlling temperature in process applications. The principal advantage the “PA” Air Pilot over standard spring loaded pilots is that pressure adjustments to the regulator can be made from a remote location. A regulator that is placed in a difficult to reach or inaccessible location can be adjusted by a remote control panel board placed in an accessible location.

Note: Temperature Control Range: 0-350°F when used with PTL & PTR Pneumatic Temperature Controllers

Model: PA Pilot
Body & Cover Material: Ductile Iron
Max Inlet Pressure:  300 PSIG
Reduced Outlet Pressure Range: 3-200 PSIG
Minimum Inlet Pressure:

  5 PSIG (w/ Low Pressure Main Valve)
Control Air Pressure Range: 3-125 PSIG
Accuracy:  ± 1 PSIG
     

PTRP Pilot

The “PTRP” Temperature Pilot is used with the HD Regulator to control temperature in various processes and systems. Some examples are: Oil heaters, Ovens, Process Heaters, Vats, Dryers and Jacketed Kettles.

The "PTRP" Pilot will control lower temperatures than the standard "PT" Pilot.

CATALOG SPEC SHEET(S)

Model: PTRP Pilot
Body Material: Ductile Iron / Cast Steel
Max Inlet Pressure:  300 PSIG
Temperature Control Range: 20-250 °F
Minimum Inlet Pressure:
  15 PSIG (w/ Std Main Valve)
  5 PSIG (w/ Low Pressure Main Valve)
     

Solenoid Pilot

The Solenoid Pilot can be used for automatic operation, remote control, programmed cycling, sequential function interlocks with other equipment, and emergency shut-off in case of power failure.

The Solenoid Pilot can be used in conjunction with Pressure, Temperature, or Air Pilots to electrically control on/off operation of the HD Regulator. When the solenoid pilot is used, the regulator can be turned on or off by electrically activating or de-activating the solenoid.

Normally Closed (nc) - Standard
The normally closed Solenoid Pilot remains closed in the non-activated state. The regulating valve will remain closed until an electrical signal is sent to the solenoid pilot. This is known as a fail-safe condition.

Normally Open (no) - Optional
The normally opened Solenoid Pilot remains open in the non-activated state. The regulating valve will function normally unless an electrical signal is used to shut-off the solenoid pilot.

Model: Solenoid Pilot
Body & Cover Material: Ductile Iron
Max Inlet Pressure:  250 PSIG
Steam Inlet Pressure: 0-180 or 180-250 PSIG
NEMA Ratings:
  NEMA 1 - Standard
  NEMA 4 - Waterproof (Optional)
  NEMA 7 - Explosion-proof (Optional)

  110 VAC (Standard)
  24 VAC (Optional)
  220 VAC (Optional)
  240 VAC (Optional)
     

PDP Pilot

The “PDP” Differential Pressure Pilot is used with the HD Regulator to maintain steam pressure at a balanced differential pressure above another media source. This is typical on an oil burner where steam used for atomization is injected into the oil burner at a set pressure above the incoming oil supply. Therefore, as oil pressure fluctuates based on demand, the steam pressure will be maintained at a differential pressure above the oil pressure.
