Self-acting temperature regulators TR40 DN15 DN25
The TR40 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 models T.205 and T.405. 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.
- 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.
- PK sensor pocket.
- K1 cooling unit.
- Diffferent capillary lenghts.
- Other thermostats on request.

AVAILABLE THERMOSTATS
T.205 – 400 N (max. closing force).
T.405 – 500 N (max. closing force).
DN 15 to DN 25.
Flanged EN 1092-1 PN 40.
T.205: 0 – 60 ºC, 30 – 90 ºC and 60 – 120 ºC.
T.405: 0 – 120 ºC and 40 – 160 ºC.
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.
