| The DP is the D-Series Regulator
with a corresponding spring controlled pressure pilot. It is used in steam pressure reducing applications requiring close accuracy with
low to high capacity requirements. With a maximum inlet pressure
of 250 psig, it controls downstream pressure between 3 and 200 psig using
three color coded spring ranges. Also available is the P5 pilot capable
of controlling pressure to within 1/2 psig. |

| The DT is the D-Series Regulator with a corresponding liquid filled
temperature pilot. Typical applications include tank heating, steam
coils, plating tanks, water heaters, steam chests, molds, and platens.
The setpoint temperature is easily adjusted with the hand knob, and an internal
bellows provides overheat protection. The pilot will control temperatures
ranging from 60°F to
260°F in five overlapping ranges. |

| The DA is the D-Series Regulator with
a corresponding air controlled pilot for controlling pressure. Downstream
pressure is maintained by delivering the proper air signal to the pilot.
This air signal can be supplied to the valve from a remote location. Three signal
pressures to downstream pressure ratios are available for pressure ranges
from 3 to 200 psi. |

| The DS is the D-Series Regulator with a corresponding electrically
actuated 120 volt solenoid pilot for on-off operation of the regulator.
Normally the solenoid pilot is used in conjunction with a pressure or temperature
pilot so that it is possible to enable or disable the steam system
with an electrical signal. Typical applications include automatic
operations, remote control, programmed cycling, sequential function interlock,
and emergency shut offs. |

|
| The DBP is the D-Series Regulator with a corresponding spring controlled
back pressure pilot. It is used to assure that a certain maximum
set pressure will not be exceeded on the upstream side of the valve.
If this maximum set pressure is reached the valve gently opens relieving
the excess pressure. Not to be used in place of a safety relief
valve. |

|
| The DPT is the Series D Regulator with both pressure and
temperature pilots. This is a classic example of using
two pilots in combination. The temperature pilot is used to control the
process temperature. The pressure pilot is used to prevent the
main valve from over pressurizing the downstream piping & components. |
