Temperature and volume control pressure balancing valve

摘要

A temperature- and flow-control valve has a housing defining a mixing chamber and having at least one outlet extending from the mixing chamber and a pair of inlets. A valve cartridge in the housing connected to the inlets opens into the mixing chamber and has a temperature-control element displaceable between an end off position with the cartridge blocking any flow from the inlets through the cartridge to the chamber through intermediate on positions with different ratios of flow from the inlets to the mixing chamber. A flow-control unit in the housing between the cartridge and the outlet includes a flow-control element displaceable between a position for maximum flow from the cartridge to the outlet and a position for restricted flow from the cartridge to the outlet. A link assembly in the housing couples the temperature-control element to the flow-control element for returning the flow-control element to the maximum-flow position on displacement of the temperature control element into the off position.
