U41S-16Q flanged piston valve is a commonly used fluid control valve, through the movement of the plunger in the valve body to regulate the flow of the medium, so as to realize the functions of fluid connection and disconnection. The valve has a simple structure, easy maintenance, good sealing, long service life and so on. Plunger valve adjustment stroke is longer than the cut-off valve, so throttling control is more difficult than the cut-off valve. It is not suitable for places with clear requirements for regulation. Widely used in petroleum, chemical, pharmaceutical, fertilizer, electric power and other industries in a variety of working conditions on the pipeline.
