Temperature control made simple

ARI-Armaturen's extended range of Temptrol selfacting control valves provide simple, economic solutions for modulating temperature control of steam, water and thermal fluid. The control systems rely on expansion and contraction of a fluid in a closed space, transferring movement to a valve stem/spindle.

Fluid expansion is constant across the selected range and results in proportional control with (theoretically) infinite turndown. The proportional band of the system is dictated by the combination of application, valve size and movement in the controller.

Easy to install and maintain, the valves are said to provide safe, accurate control.
