Carraro - Control valve AT
AT series even modulating temperature regulator, which utilizes steam pressure as the activating force. The reason for the rapid reaction is due to bellows seal, calibrated spring and the low thermal inertia. All of this makes the regulator respond quickly to very small deviations at the controlled temperature.
The use of this type of self-activating regulator provides a precise and economical solution to many temperature control purposes, which eliminates the need for electrical or pneumatic solution models.
This type of temperature regulator can be supplied with single or double seat as well as in 2 or 3-way design. Face-to-face dimensions according to EN 558-1 (DIN 3356). The use of bellows eliminates leaks in the regulator, bellows also protects the internal moving parts
