Description

The Watson McDaniel HD-13-N Pilot-Operated Regulator Valve was designed for extremely accurate control of temperature and pressure in steam service applications. The HD-Series is made of Ductile Iron for extended pressure and temperature ratings when compared to cast iron. Several different control pilots can be mounted to the valve to control pressure, temperature, or a combination of both. When two or more pilots are used together (both a pressure and a temperature pilot) an additional pilot adapter for the second pilot is required (must indicate when ordering). The most common pilots are the PP-Pilot for pressure reducing, and the PT-Pilot for temperature control.

The Standard Main Valve is used for an inlet steam  pressure range of 15-300 PSI.
The Low-pressure Main Valve 
contains a different main valve spring and is available for an inlet  pressure range of 5 – 20 PSI. The Main Valve and Pilot are purchased separately.

Features:

  • No external power source is required.
  • Pressure & 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.
