Rostra Vernatherm's 2 Port Thermostatic Control Valves thermally control any fluid inline in any system

There are two styles of these valves, our standard unit and our positive shut off unit.

Standard valves allow a bleed through, which allows the valve to rapidly sense system temperature and respond.

Positive Shut-Off valves are for those applications where a bleed through will not work, positive shut off units are sealed., and will not leak in the closed position.
