Watson McDaniel HD-12-N TWMHD12N

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 and more) to control the operation of the main valve. The HD Series has a ductile iron body, pilot and main valve are selected separately.

• No external power source is required
• Pressure and temperature pilots can be used in combination, eliminating the need for a separate pressure and temperature regulator
• Ductile iron body for higher pressure ranges and increased safety when compared to cast iron
• Full port strainer and blowdown valve on pilot adapter for ultimate protection against dirt and scale
• Hardened stainless steel trim (55 Rc) for extended life even in the most demanding applications
• The innovative design allows the pilot to be mounted on either side of the regulator and is easily field reversible without having to rebend tubing
• Tubing and pilot adapter is pre-mounted on main valve
• The control pilot requires only four bolts to complete the installation
