Your cart is empty.This thermal actuator (zone valve) is a thermally activated, slow-opening valve that provides individual flow control (per loop) on a multi-zoned manifold (manifold serving more than one zone) in a water/glycol radiant floor heating system. Actuators are normally closed (NC)and will open when power is applied. Travel time for the actuators is approximately 90 sec. to close. It is compatible with Nordik Radiant manifolds and many other brands.

I had three bad drive actuators, and these replacements work just great.
