ADCA SELF-ACTING TEMPERATURE REGULATORS TR25SS (1/4" and 3/8") DESCRIPTION The TR25 series of temperature regulators were designed for direct acting temperature control systems where the valve closes on temperature rise. They are single seated, unbalanced and intended to be coupled with T series thermostat model T.205. The liquid filling the thermostat expands when the temperature of the fluid being heated rises, closing the valve. These valves are used for controlling temperature in central and district heating systems, heat exchangers and other HVAC and industrial applications. MAIN FEATURES Easily adjustable temperature range. Proportional temperature control. Single seated, two way, direct acting valve. Built-in strainer. Narrow thermostat neutral zone (1,5 to 2,5 ºC). No special tools required for servicing. Stuffing box is an integral part of the thermostatic element, allowing easy and simple maintenance of the valve. OPTIONS: PK sensor pocket. K1 cooling unit. Diffferent capillary lenghts. Other thermostats on request. Saturated and superheated steam. Hot and superheated water. AVAILABLE VALVES: TR25SS – stainless steel. PK sensor pocket AVAILABLE THERMOSTATS: THERMOSTAT RANGES: Horizontal installation with the thermostat in the vertical position, in order to reduce wear. In case of medium temperatures up to 150 ºC, the thermostat may be fitted below or above the valve. In case of medium temperatures between 150 and 250 ºC, a cooling unit type K1 has to be applied with the connection pointing downwards. A “Y” strainer should be installed upstream of the valve. See IMI – Installation and maintenance instructions. VALSTEAM ADCA BODY LIMITING CONDITIONS PN 40 ALLOWABLE PRESSURE RELATED TEMPERATURE Minimum operating temperature: -10 ºC.

ADCA TR25 – T SERIES THERMOSTATS – FTO, UNBALANCED TRIM, METAL SEALING (CLASS IV) Kvs (m³/h) MAX. PERMISSIBLE PRESSURE DROP PROPORTIONAL BAND The proportional band is the temperature change required for the valve to move from its fully open to fully closed position. It depends on the valve stroke (mm) and on the thermostat movement per ºC (mm/ºC), and is calculated as follows: Proportional band = Valve stroke (mm) Thermostat movement (mm/ºC) Thermostat movement for T.205 and T.405: 0,5 mm/ºC. A proportional band between 8 ºC and 13 ºC is suitable for most applications. A smaller...

Stainless steel / Graphite * Valve plug * Available spare parts. K1 COOLING UNITS Cooling units are used as a means of protection for the stuffing box when dealing with high temperatures. The K1 cooling unit should always be applied when medium temperatures are between 150 ºC and 250 ºC. For higher temperatures as well as for all hot oil systems please consult. PK SENSOR POCKETS Sensor pockets made of stainless steel can be supplied with all TR series self-acting thermostats using rod sensors. A sensor pocket, also called thermowell, is used to protect the sensor and to allow its removal...
