ABSTRACT:
A valve has a base body fitted in an opening and having a through passage formed at one end with a first valve surface. A valve element in the base body and has axial ends one of which forms second valve surface sealingly fittable with the first valve surface to close the through passage. A stem in the through passage is coupled to the valve element to move it between the closed and open positions. A plurality of abutment arms projecting inward from an inner peripheral wall of the through passage define with a shaft region of the valve element a clearance and define a radial gap between opposite arms which is greater than a radial dimension of the shaft region and smaller than a radial dimension of a shoulder of the valve element.
