Overview of electronic electric single seat control valve

Main parts material Body, bonnet: HT200, ZG230-450, ZG1Cr18Ni9Ti Spool: 1Cr18Ni9Ti, Si TiLai alloy surfacing, reinforced PTFE filler: PTFE, flexible graphite, stainless steel bellows putter, liner Set: 2Cr13 Gasket: Asbestos rubber sheet, 1Cr18Ni9Ti, Graphite Wound Gasket is widely used in the production automation control of electric power, metallurgy, chemical industry, petroleum, textile, pharmaceutical, paper and other industrial sectors. ZDLP, ZDLM electronic electric single-seat, sleeve valve, to adjust the instrument to receive the DC current signal, change the media to be adjusted to make the controlled process parameters at a given value. One electric single-seat control valve for smaller pressure, medium viscosity or slightly particulate impurities occasions; electric sleeve valve is suitable for large pressure drop and large leaks occasions. This series of products nominal diameter from 20 to 300mm, the nominal pressure of 1.6,4.0,6.4 MPa, to accept the signal 0 ~ 10mA.DC or 4 ~ 20mA.DC, the use of temperature range from -40 ℃ ~ 450 ℃.
