Watson Mcdaniel pp-b Cast Steel Pressure Pilot 20-100 Psig

Product Description

The WATSON MCDANIEL pp-b is a cast steel pressure pilot designed for use with HD-series pilot-operated steam pressure regulators. It controls downstream steam pressure in steam mains and process equipment applications. The pp-b features a blue spring that enables a downstream adjustable pressure range of 20 to 100 PSIG, with 1 PSI accuracy. Stainless steel trim provides durability in steam service. This pilot is suited for most industrial steam pressure control applications where consistent downstream pressure is required despite fluctuations in inlet pressure or varying steam demand.

The pp-b is applied in industrial steam distribution systems where a pilot-operated regulator is used to maintain stable downstream pressure. It is installed as the pilot component on HD-series regulators serving steam mains or process equipment. Pilot-operated regulators paired with this pilot maintain constant downstream pressure even when inlet pressure fluctuates or steam usage varies across the system. It is appropriate for industrial facilities operating steam systems within the 20 to 100 PSIG range.

Key Features

• Cast steel body construction for industrial steam service durability
• Stainless steel trim for corrosion resistance in steam applications
• Blue spring provides 20 to 100 PSIG downstream adjustable pressure range
• 1 PSI accuracy for reliable pressure control in most industrial applications
• Pilot-operated design maintains constant downstream pressure under variable inlet conditions

Compatibility

Designed for use with the WATSON MCDANIEL HD-series pilot-operated regulator for steam pressure control in steam mains and process equipment.

Installation Notes

Installation of pressure pilots on steam regulators is typically performed by licensed pipefitters or steam system technicians. Isolate and depressurize the steam system completely before servicing or installing any pilot or regulator components. Verify that system operating pressure falls within the pilot spring range before commissioning. All steam piping work should comply with applicable ASME and local mechanical codes.
