供应意大利STI***器-AL系列气锁阀意大利STIhttp://-产品名称：AL系列气锁阀产品型号：AL102产品简介：AL系列气锁阀由先导装置和三通阀组成一套，尺寸有1/4",1/2",1",1-1/2"在气动执行器上装一个气锁阀，无论何时当空气压力下降到低于操作安全点时，它们将执行器与控制装置（***器，电气分配器等）隔离，保证执行器的特殊安全位置。气锁装置主要由一个带设定值校正和大约20千帕差压的气动压力开关所组成，操作一个或多个三通同步换向器(取决于所需要的功能)。当空气压力在设定值周围摆动时，差压避免了连续的不合适的换向。空气压力下降到设定值,开关装置立即动作，在空气压力逐渐下降到设定值的情况下也是如此。AL-Air-LockTheAirLockpressurestaticdeviceALismountedonpneumaticactuatorswhentheyaretobeisolatedfromcontroldevicespositioners,electro-pneumaticdistributors,etc.wheneverairpressurefallsbelowoperatingsafetypoint.ThepressureswitchdeviceALhasbeendesignedtomeetdifferentair-locksystems,toguaranteeaspecificsafetypositionofactuators,asrequiredbythefinalcontrolelement.TheAir-Lockdevicec***istsmainlyinapneumaticpressureswitchwithsetpointcalibration.Thehysteresisis20kPa15PSIapproximately.Thisitemoperatesoneormore3-waysynchronouscommutators,dependingonthefunctionrequired.Switchingdeviceoperatesimmediately,alsoincaseofagradualair-pressuredecreasetothesetvalue.Thedifferential***oidsacontinuous,inopportunecommutationwhenair-pressureswingsaroundthesetpoint.关键词导航：德国LABOMhttp://-E+Hhttp://-)
