Abstract
A pressure balancing valve and method of assembly is disclosed. The valve includes a pressure balancer cartridge having a poppet assembly made up of releasably connectable poppet valves movably mounted on opposite sides of a diaphragm. The pressure balancer cartridge utilizes compliant members mounted on water flow controlling orifices to form a sealable opening in cooperation with the closure surface of a respective poppet. Each poppet has a reduced diameter end that fits within a damping chamber and uses a sealing member mounted on each poppet valve to increase tolerances and improve manufacturing yield. The method includes the step of aligning poppet halves and connecting the interlocking connectors of the two halves through a diaphragm.
