ACTION:
Direct; Pilot Output Pressure (Yellow) increases with temperaturerise.
APPLICATION:
For temperature controlled system shutdown until manuallyreset.
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 consists of a Direct Action Base Assembly sending a signal to a 3 PGM Pilot. The 3 PGM Pilot is connected so that once the Output Pressure (Yellow) is vented, it must be manually reset to resume service.
Assume the set temperature of the Thermostat is below that of the system. The vents at BALL 1 (Orange to Atmosphere) and
BALL 3 (Yellow to Atmosphere) are closed. The Inlets at BALL 2 (Yellow to Orange) and BALL 4 (Violet to Yellow) are open. Output Pressure (Yellow) is being sent to any Pilot or Motor Valve.
As the temperature decreases in the system, the STAINLESS TUBE decreases in length to move the Thermostat Diaphragm Assembly in a direction to first close the seat at BALL 2 (Yellowto Orange) and open the seat at BALL 1 (Orange to
Atmosphere). Venting Variable Pressure (Orange) moves the 3PG Pilot Diaphragm Assembly upward to close the seat at BALL
4 (Violet to Yellow) and open the seat at BALL 3 (Yellow to Atmosphere). Output Pressure (Yellow) decreases to cause the
desired Pilot or Motor Valve action.
Once the Output Pressure (Yellow) has been vented the Thermostat is shut-down until the temperature of the system is
above the set temperature and the RESET LEVER is used to reset the Pilot. If desired the RESET LEVER can also be used
to manually vent Output Pressure (Yellow) and shut-down the thermostat.
