ACTION:
Direct semi-throttle; Pilot Output Pressure (Yellow) increases with temperature rise.
APPLICATION:
Low temperature shut down, direct action temperature controller requiring semi-throttling direct action.
For piped vent in Direct or Indirect mode.
WORKING PRESSURE (sensing element):
psig kg/cm2
500 35.15 max. without Separable Socket
4000 281.23 max. with Separable Socket
7000 492.15 max. with Special Separable Socket
Separable Socket is an extra price item and must be ordered separately, if desired. To order Separable Sockets refer to Table of Contents
TEMPERATURE RANGE:
-30°F minimum To 400°F maximum
-34°C minimum to 204°C maximum
SUPPLY PRESSURE:
5 to 30 psig
.35 to 2.11 kg/cm2
OPERATION:
This Thermostat Base Assembly consists of a STAINLESS TUBE for monitoring the changing temperature, which is connected by a Low Expansion Alloy Rod to a DIAPHRAGM ASSEMBLY. The differential pressure across the Diaphragm combined with the changes in the length of the STAINLESS TUBE semi-throttle a PILOT PLUG valve. The PILOT PLUG consists of two stainless balls rigidly connected together. The seat at BALL 1 is the pressure vent (Yellow to Atmosphere).The seat at BALL 2 is the Supply Pressure inlet (Violet to Yellow).
Assume the set temperature of the Thermostat is above that of the system. The Inlet at BALL 2 is closed and the vent at BALL 1 is open. Output Pressure (Yellow) is vented away so that no signal is being sent to the Pilot or Motor Valve.
As the temperature rises in the system, the STAINLESS TUBE increases in length to move the Thermostat Diaphragm Assembly in a direction to first close the seat at BALL 1 (Yellow to Atmosphere) and open the seat at BALL 2 (Violet to Yellow). Output Pressure (Yellow) increases and acts on the DIAPHRAGM accounts for the semi-throttle action of the
Thermostat. Output Pressure (Yellow) increases to cause the
desired Pilot or Motor Valve action.
As the temperature decreases, the action is reversed to decrease or vent Output Pressure(Yellow).
By reversing the Vent and Supply lines, the Thermostat can be made to act in an indirect throttle mode, Pilot Output Pressure decreases with temperature rise. In this mode the “DA” Thermostat acts identical to the standard T 12 Thermostat with
the exception of being able to pipe the vent line away from the thermostat.
