TEMPERATURE CONTROLLERS
OPERATION: These Thermostat Base Assemblies consist of a STAINLESS TUBE for monitoring the changing temperature, which is con-nected by a Low Expansion Alloy Rod to a DIAPHRAGM or BELLOWS ASSEMBLY. The differential pressure across the Diaphragm or Bellows combined with changes in the length of the STAINLESS TUBE throttle a PILOT PLUG seat. The PILOT PLUG consists of two stainless balls rigidly connected together. The seat at BALL 1 is the Supply Pressure inlet (Violet to Yellow). The seat at BALL 2 is the pressure vent (Yellow to Atmosphere). Assume the set temperature of the Thermostat is above that of the system. The vent at BALL 2 is closed and the inlet at BALL 1 is open. Output Pressure (Yellow) is being sent to any Pilot or Motor Valve. As the temperature rises in the system, the STAINLESS TUBE increases in length to move the Thermostat Diaphragm (or Bellows) Assembly in a direction to first close the seat at BALL 1 (Violet to Yellow) and open the seat at BALL 2 (Yellow to Atmosphere). Output Pressure (Yellow) decreases to cause the desired Pilot or Motor Valve action. As the temperature decreases, the action is reversed to increase Output Pressure (Yellow). By reversing the Vent and Supply lines, the Thermostat can be made to act in a direct snap mode, Pilot Output Pressure increases with temperature rise. Pilot output vents with tempera-ture decrease.
