For use in gas control and safety systems in all sectors of the iron, steel, glass and ceramics industries, also in commercial heat generation applications.Modular design saves space and piping work. The main gas valve, pilot valve, regulator and pressure switch are all available for direct stack mounting for a single small modular footprint. Changeable mounting plates make it easy to reduce input/output and flange sizes. Reduces need to keep multiple sizes in inventory.?Key SpecificationsCompact design and easy installationMax inlet pressure of 500 mbar (500 hPa/7 psig)Mercury-free pressure switch has test port and <25% deadbandProof of closure switch with integral visual position indicatorEC type-tested and certified, FM, CSA, UL, and AGA approved?选型参考??KROM SCHRODER电磁阀VAS系列其他常见型号：KROM SCHRODER VAS1T15N/NKKROM SCHRODER?VAS110R/NWKROM SCHRODER?VAS110R/NWSRKROM SCHRODER?VAS110R/NKSRKROM SCHRODER?VAS110R/NQKROM SCHRODER?VAS1T10N/NQKROM SCHRODER?VAS115R/NWKROM SCHRODER?VAS115R/NWSRKROM SCHRODER?VAS115R/NKKROM SCHRODER?VAS115R/NKSRKROM SCHRODER?VAS115R/NQ?KROM SCHRODER Solenoid valves?NEW + ORIGINAL+ ONE YEAR WARRANTY? / :.KROM SCHRODER电磁阀VAS240R/NW 88000024产品参数
