Abstract:
This fluid valve is provided with: a main body (11) having at least one opening (11b, 11c); a valve body (12) which adjusts the opening degree of said at least one opening (11b, 11c) by rotating inside the main body (11); a sealing member (13) which elastically deforms between the main body (11) and the valve body (12); and a sliding coat (14) which is provided on the outer surface of the valve body (12) and rotates together with the valve body (12) to slide on the seal member (13) by rotating. The method for manufacturing the fluid valve includes a heating step for: covering the outside of the valve body (12) with the sliding coat (14), by using, as the sliding coat (14), a coat obtained by forming a heat shrinkable material into a cylinder shape; heating the sliding coat (14) to bring the sliding coat (14) into close contact with the outer peripheral surface of the valve body (12). The method for manufacturing the fluid valve includes an insert-molding step for insert-molding the valve body (12) and the sliding coat (14).
