MIXING TEE CHECK VALVE AND METHOD Abstract of the Disclosure A mixing valve includes a housing having inlet ports and an outlet port that intersect at a valve chamber. A valve core within the valve chamber includes passages in fluid communication with the inlet and outlet ports. The passages intersect at a cavity within the valve core. An elastomeric seal retained within the cavity sealingly engages the valve core around the passages in the absence of fluid pressure in the inlets. Injection of a pressurized fluid in one of the inlets causes the seal to move away from both the corresponding inlet passage to permit fluid flow from the pressurized inlet port to the outlet port and compresses the seal around the other inlet port to provide a tighter seal than existed before application of pressure to the first port.
