 Temperature Control Valves > Mark 85 Series



MK85 Series The Mark 85 Series is a self-operated temperature regulator with controlled failure option which allows you to predetermine the position of the valve in the event of a thermal system failure. The Mark 85 is designed to fail closed on heating applications and to fail open on cooling applications.

An inherent feature of the controlled failure design is that it is slower responding than a standard temperature regulator and cannot compensate as quickly for rapid load changes. It is ideal for slower responding systems such as autoclaves and large storage tanks.
