Proportional valve Product Description: proportional valve Product Overview: "proportional valve" is an automated pipeline to reduce work stress specialized devices, "proportional valve" is the use of a control valve body opening and closing the opening of the piece to regulate the flow of the medium, the pressure medium is reduced, while the role of the pressure regulating valve after the aid of the opening and closing parts, so that the valve pressure is kept within a certain range, "proportional valve" characterized in the case of changing the inlet pressure, outlet pressure is maintained within a certain range of values. Proportional valve main parts material: Part name Material Body bronze or stainless steel piston import export gland gland proportional valve main technical parameters: Model within Y13X-16T Y43X-16T threaded flange connection suitable for medium water, Gas Temperature ≤90 ℃ rated working pressure 1.6MPa pressure error ± 2.5% minimum open 2:01 0.2MPa 3:01 0.3MPa pressure proportional valve main dimensions: Model DN (mm) L (mm) Y43X-16 2: 13: 13: 24: 15: 15: 2 25 115 321,244,013,250,140 6,515,580,155,100,200,125 220,150,230,200,270 proportional valve installation and proportional pressure valve maintenance should note the following: 1. To proportional valve operation and easy maintenance, the proportional valve is generally mounted on a horizontal pipe vertical, horizontal installation must be specified. 2. Before proportional valve operation of pipelines must be flushed, do not allow dirt into the valve body. 3. Install the proportional valve should pay attention to the flow of the pipeline and valve off the media on the arrow in the same direction. 4. In order to prevent the overpressure valve pressure should be proportional valve from the outlet of a safety valve installed at least 4M.
