FEATURED PRODUCT: WATSON MCDANIEL HD Series Pilot Operated Regulators
Pilot-Operated Regulators
The HD-Series Pilot-Operated Regulators are used on steam applications for pressure reduction or controlling product temperature (when steam is used in heating applications). The Pilot-operated regulators are more accurate and available in higher capacity than Direct-Operated regulators. The HD Series regulators use a pilot valve (several types and styles including Pressure, Temperature, ON-OFF solenoid, etc.) to control the operation of the Main Valve. The HD series has a Ductile Iron Body; Pilot and Main-Valve are selected separately.
A complete HD Series regulator consist of a main valve and an operating pilots(s). Each are selected separately.
Controlling Temperature & Limiting Pressure to a Maximum Value
The PT & PP Pilot combination is used when it’s required to control temperature while limiting downstream pressure to a maximum value. The downstream pressure is limited to a maximum setting by the pressure pilot, while the temperature pilot maintains the correct temperature of the process.
