Single-lever mixing valve with override

摘要

A valve assembly has a housing having an abutment and a valve cartridge in the housing having an actuating stem displaceable about a flow-control axis for varying a flow rate between a maximum flow and a minimum flow and about a temperature-control axis for varying temperature of the flow. A handle connected to the stem carries another abutment engageable with the housing abutment in a position of the valve cartridge corresponding to partial flow through the cartridge. A deflectable override button on the handle is operable to displace the handle abutment out of engagement with the housing abutment.
