ABSTRACT:
A fluid control valve includes a housing defining therein a fluid passage. The fluid control valve further includes a valve member for controlling a fluid flow in the fluid passage by communicating and blocking by the fluid passage. The fluid control valve further includes a protection member being press-inserted into the housing for protecting the housing from heat of the fluid flow in the fluid passage. The housing is formed by die casting of an aluminum material. The protection member and a wall surface, which defines the fluid passage in the housing, define therebetween a thermal insulating layer for restricting thermal transmission of the fluid flow from the protection member toward the housing.
