とを特徴とするピストンバルブ。[Claims for Utility Model Registration] (1) The switching operation of the valve is performed by the pushing action of the piston using air pressure, and there is an upper valve in the valve body that communicates between the inlet and the outlet. The hole and a lower valve hole that communicates between the outflow port and the drain outlet are vertically opposed to each other, and the lower end of the valve stem connected to the piston has a threaded portion at its tip. A small-diameter portion is formed, and a valve body for opening and closing the two valve holes and a guide washer are sequentially attached to the small-diameter portion, and these are tightened with a nut screwed onto the threaded portion. 1. A piston valve installed in a replaceable manner, wherein the guide washer is made of a zirconia-based ceramic material. (2) The valve switching operation is performed by pushing the piston using air pressure, and the valve body has an upper valve hole that communicates between the inlet and the outlet, and a drain hole between the outlet and the drain. A lower valve hole that communicates with the opening is provided in a vertically opposed manner, and a small diameter portion with a threaded portion at the tip thereof is formed at the lower end of the valve stem connected to the piston. A valve body for opening and closing both valve holes and a guide washer are sequentially attached to the small diameter portion, and these are attached in a replaceable state by tightening a nut screwed onto the threaded portion. 1. A piston valve, characterized in that the valve seat portion having the lower valve hole is formed of a zirconia-based ceramic material.
