The HIBE BK27-DN40/50 is a robust, self-acting thermostatic regulator engineered for precise temperature control in various industrial and commercial systems. Known as a “Thermovitregler,” this device operates without any auxiliary electrical or pneumatic power, making it a reliable and energy-efficient solution. Its finned body design aids in thermal dissipation, ensuring stable performance. The regulator automatically modulates the flow of a heating or cooling medium to maintain a set temperature. Featuring a straightforward top adjustment mechanism, the BK27 is ideal for controlling temperatures in heat exchangers, storage tanks, and process applications for pipelines with nominal diameters of DN40 and DN50.
