The Watson McDaniel HD-Series Pilot Operated Regulators were
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. These
regulators use several different control pilots, which
can be attached to the valve to control pressure,
temperature, or a combination of both. The different
control pilots can be added or removed from the
regulator body. This modular design adds to the versatility of this
product. The most common options include the P-Pilot for pressure reducing, and the T-Pilot for temperature control.
