A pressure balancing valve has a pair of fluid ducts for hot and cold water, a butterfly type valve is located in each duct, a pressure cavity is provided that is in communication with each duct, and a resilient diaphragm mounted in the cavity converts pressure differential between the ducts into positional displacement of a rod-like pressure plate linkage secured to the butterflies. The butterflies pivot to alter fluid flow in the ducts until substantially equal pressures appear at the outlets of the ducts.
