LOW TEMPERATURE BASE ASSEMBLIES APPLICATIONS: Used to control a set temperature in indirect heaters, emulsion treaters, reboilers, steam generators, heat exchangers, cooler shutter controls, and salt

1 LOW TEMPERATURE BASE ASSEMBLIES APPLICATIONS: Used to control a set temperature in indirect heaters, emulsion treaters, reboilers, steam generators, heat exchangers, cooler shutter controls, and salt bath heaters. CERTIFICATIONS: Canadian Registration Number (CRN): 0H Kimray is an ISO certified manufacturer ACTION: Indirect: Pilot Output Pressure (Yellow) decreases with temperature rise. Direct: Pilot Output Pressure (Yellow) increases with temperature rise. WORKING PRESSURE (sensing element): psig kg/cm max. without Separable Socket max. with 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/cm 2 RESPONSE RANGE: T psig/ F,.22 kg/cm 2 / C OPERATION: These Thermostat Assemblies consist of a STAINLESS TUBE for monitoring the changing temperature, which is connected by a Low Expansion Alloy Rod to a DIAPHRAGM or BELLOWS ASSEMBLY. The differential pressure across the 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. Indirect: 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 (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. Direct: 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 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 increase Output Pressure (Yellow).
