-Challenge: A new type of heating coil was designed to use a very high delta T. The concern with valve clogging was raised.

- Solution: To allow a very high Delta T, the coil specification calls for a very low flow coefficient (Cv/Kv).
Working with the coil manufacturer in their lab, Spartan, designed an actuator that would be able to automatically flush debris upon clogging.
A specific actuator, ME4343, based on our current ME4340 was designed accordingly.
Independent from the controller signal, if request for heating was not match within certain perimeters the actuator would fully open the valve to allow flushing of debris.
