Pilot-Operated Regulators are higher in capacity and more accurate than standard self-operated regulators. Pilot-Operated Regulators will maintain constant set outlet pressure even when inlet pressure fluctuations or variations in flow occur. With the proper selection of pilots, these regulators will accurately control temperature, pressure, or a combination of both.

TYPICAL APPLICATIONS

The HD or D Regulator with the "P" Pressure Pilot is used for reducing steam pressure in piping mains and process applications. Pilot-operated regulators will maintain constant downstream pressure even when the inlet pressure to the regulator fluctuates or steam usage varies.

FEATURES

• The "P" Pilot can maintain downstream pressure to ±1 PSIG
• Optional "P5" pilot can maintain pressure to ±0.5 PSIG
• Choices of three overlapping pressure ranges
• Pressure adjusting spring can be changed with regulator in-line
• Pilot is installed using four bolts
• Full port strainer and blow-down valve on pilot adapter to eliminate failure caused by contaminated steam systems
• Watson McDaniel's pilots can be used with other manufacturer's regulators
• Reduced Outlet Pressure Range: 3-200 PSIG
• Inlet Pressure Max: 300 PSIG
• Inlet Pressure Min: 15 PSIG

The HD-Series is the upgraded model for the D-Series Regulator.

HD & D internal components and pilots are interchangeable.
