Abstract:
An automatic modulating regulator device for use with a non-electrical hot water heat source supplied by a pressurized water supply and having a hot water circuit to pump hot water to heat exchange elements, said regulator device comprising valve means adapted to be connected to a hot water return conduit of said hot water circuit, said valve means having an actuator means for placing said regulator device in a normally open condition in response to an electrical power failure, a self-powered thermostatic valve responsive to a temperature sensing means, for placing said regulator device in an open condition in response to heat demand by said temperature sensing means, and flow restrictor means for releasing controlled quantities of water from said return hot water conduit of said hot water circuit through said regulator device when both said valve means and thermostatic valve place said regulator device in an open condition, said valve means and said thermostatic valve being independently connected to a common valve disc disposed in obstruction to a flow-through conduit provided in a valve body of said regulator device.
