Description Self contained temperature regulators are used to control the temperature of a process by regulating the flow of steam (heating applications) or cold water (cooling applications) to the heat exchanger or process vessel.  These regulators require no external power to operate, so they are ideal for remote or hazardous locations.  Temperature setpoint is easily adjusted by rotating the knurled adjustment wheel.  Temperature wells are available in several materials to isolate the process fluid from the bulb and to simplify maintenance. Series 175 Direct Acting Temperature Regulator The Series175 Temperature Regulators are single seated, balanced self actuated vapor tension units.  They are specifically designed for general service heating applications where accurate control of temperature is critical.   Series 175T w/ union end connections (optional dial thermometer show) CVs: up to 113 Maximum inlet pressure: 250 psig [17.2 bar] Control temperature range: 20°F to 240°F [-7°C to 116°C] Sizes: 1/2" to 4" Connections: NPT - 1/2" to 2" Union - 1/2" to 2" 125 lb Flg - 2" to 4" 250 lb Flg - 2" to 4" Body material: Bronze - 1/2" to 1-1/2" Cast iron - 2" to 4" Stainless steel valve trim Weight: 12 to 160 lbs [5 to 73 kg] Series 153 Reverse Acting Temperature Regulator   The Series175 Temperature Regulators balanced self actuated vapor tension units.   They are specifically designed for general service cooling applications where accurate control of temperature is critical. Series 153 w/ union end connections (optional stainless steel dry well show) CVs: up to 113 Maximum inlet pressure: 150 psig [10.3 bar] Control temperature range: 2 0°F to 240°F [-7°C to 116°C] Sizes: 1/2" to 4" Connections: NPT - 1/2" to 2" Union - 1/2" to 2" 125 lb Flg - 2" to 4" 250 lb Flg - 2" to 4" Body material: Bronze - 1/2" to 1-1/2" Cast iron - 2" to 4" Stainless steel valve trim Weight: 12 to 160 lbs [5 to 73 kg]
