PARKER派克PRDM系列直动式减压阀描述：PRDM系列元件为直动式减压阀。主要用于将液压系统中的某一支路压力调节到系统公称压力以下的某一预定值。此外，还将该支路的溢流功能集于一体。压力表接口或测量接口直接在元件上，以便控制支路压力。功能该阀为常开元件，在设定值以下它允许油液自由地流过控制流道。当下游流道中压力升高至预调节的压力时，阀芯向关闭的方向移动，以减少来自主系统的流量，缓冲柱塞将自行调整，以维持预定的支路系统压力。当支路系统压力由于外力作用升高时，缓冲柱塞将克服弹簧力移动并且使大量的油液流回油箱，使压力不再继续升高。泄漏油通过弹簧腔流回油箱。PARKER派克PRDM系列直动式减压阀型号：PRDM2PP02SVCPRDM2PP06SVG15PRDM2PP02SVG15PRDM2PP16SVG15PRDM2PP21SVG15PRDM2AA02SVG15PRDM2AA06SVG15PRDM2AA16SVG15PRDM2AA21SVG15PRDM2BB02SVG15PRDM2BB06SVG15PRDM2BB16SVG15PRDM2BB21SVG15RDM2PT02SVG15RDM2PT06SVG15RDM2PT21SVG15RDM2TT02SVG15RDM2TT06SVG15RDM2TT16SVG15PRDM2PX06SVG15SDM2PP06SVG15PRDM2PP06KVG15PRDM2PP02KVG15PRDM2PP02LVG15PRDM2PP06LVG15PRDM2AA06KVG15PRDM2AA06LVG15PRDM2BB06KVG15PRDM2BB06LVG15PRDM2PP06SVS15PRDM2PP06SVM15PRDM2PP06SVC15PRDM2AA06SVM15PRDM2AA02SVM15PRDM2BB06SVM15PRDM2BB16SVM15PRDM2PP02SVM15PRDM2PP16SVM15PRDM2PP21SVM15PRDM2PP16KVG15PRDM2BB16KVG15PRDM2PP06KVS15PRDM2AA16LVG15PRDM2BB16LVG15PRDM2PP16LVG15PRDM2PP16KVS15PRDM2PP21KVS15PRDM2AA16KVS15PRDM2BB06KVS15PRDM2AA06LVG15X797PRDM2BB06SVG15X797PRDM2PP06SVG15X797PRDM2AA06SVG15X797PRDM2PP06LVG15X797PRDM2PP16SVG15X797PRDM2BB16SVG15X797PRDM2AA16SVG15X797PRDM2BB06LVM15PRDM2AA21KVG15PRDM2PP21SVG15X797PRDM2BB16LVM15PRDM2PP16LVG15X797PRDM2PP06LVM15PRDM2AA06LVM15PRDM2PP02LVM15PRDM2PP16LVM15PRDM2PP06LVC15PRDM2PP21KVG15PRDM2BB02LVM15PRDM2BB02LVG15PRDM2AA02LVG15PRDM2PP35SVG15X797PRDM2AA02SVG15X797PRDM2PP21SVG15X862PRDM2AA02LVM15PRDM2BB35SVG15PRDM2PP35SVG15PRDM2AA35SVG15PRDM2PP35KVG15PRDM2PP16SVG15X738PRDM2PP16SVG15X862PRDM2AA16KVG15PRDM2PP16SVC15PRDM2PP21SVC15PRDM2PP35LVG15PRDM2BB21KVG15PRDM2PP16LVC15PRDM2AA02KVGPRDM2AA21LVG15PRDM2AA35KVG15PRDM2BB35KVG15PRDM2PX02SVGPRDM2PP21KVGX797PRDM2BB16SVGX825PRDM3PP01SVGPRDM3AA01SVGPRDM3BB01SVGPRDM3PP05SVGPRDM3PP10SVGPRDM3PP15SVGPRDM3PP21SVGPRDM3BB05SVGPRDM3BB10SVGPRDM3BB15SVGPRDM3BB21SVGPRDM3BB05LVGPRDM3PP01LVGPRDM3PP05LVGPRDM3PP10LVGPRDM3PP15LVGPRDM3PP21LVGPRPM2PP20KVPRDM3AA05SVGPRDM3AA10SVGPRDM3AA15SVGPRDM3AA21SVGPRDM3BB01LVGPRDM3BB10LVGPRDM3BB15LVGPRDM3BB21LVGPRDM3AA01LVGPRDM3AA05LVGPRDM3AA10LVGPRDM3AA15LVGPRDM3AA21LVGPRDM2BB16SVCPRDM2BB21SVGX797PRDM3PP10SVGX825PRDM2AA16SVSPRDM3PP10LVMPRDM2BB21LVGPRDM2BB16LVGX797PRDM3BB10SVMPRDM2PP21KVMPRDM2PP02KVMPRDM3BB21SVMPRDM2AA16SVMPRDM2BB02KVCPRDM2PP02SVSPRDM2AA21SVCPRDM3PP05SVCPRDM2BB21SVCPRDM3PP15SVCPRDM3AA21SVCPRDM2BB35KVC15PRDM3PP05SVGXG136PRDM2AA06KVCPRDM2PP06KVCPRDM3PP15SVGXG136PRDM3PP21SVGXG136PRDM3AA21SVGXG136PRDM3PP10SVGXG136PRDM3AA10SVGXG136PRDM3AA15SVGXG136PRDM3BB15SVGXG136PRDM3BB21SVGXG136PRDM2PX16SVGPRDM2AA21SVGX797PRDM2AA01KNNPRDM2AA01KVNPRDM2AA01SVNPRDM2AA02KNSPRDM2AA02LNMPRDM2AA02SNGPRDM2AA02SNNPRDM2AA02SNSPRDM2AA02SVNPRDM2AA02SVYPRDM2AA06KNNPRDM2AA06KNSPRDM2AA06KVNPRDM2AA06KVSPRDM2AA06LNGPRDM2AA06LNNPRDM2AA06LVNPRDM2AA06LVSPRDM2AA06SNGPRDM2AA06SNMPRDM2AA06SNNPRDM2AA06SNSPRDM2AA06SVNPRDM2AA16KNNPRDM2AA16KNSPRDM2AA16KVNPRDM2AA16SNGPRDM2AA16SNNPRDM2AA16SNSPRDM2AA21KNNPRDM2AA21KNSPRDM2AA21KVNPRDM2AA21KVSPRDM2AA21LVSPRDM2AA21SNGPRDM2AA21SNNPRDM2AA21SVYPRDM2AA35KVSPRDM2AA35SNNPRDM2AA35SNSPRDM2AA35SVNPRDM2BB01LNSPRDM2BB01SVSPRDM2BB02KVGPRDM2BB02LNMPRDM2BB02SNMPRDM2BB02SNNPRDM2BB02SVNPRDM2BB06KNGPRDM2BB06KNNPRDM2BB06KNSPRDM2BB06KVNPRDM2BB06LNGPRDM2BB06LNMPRDM2BB06LNNPRDM2BB06LNSPRDM2BB06LVNPRDM2BB06SNGPRDM2BB06SNMPRDM2BB06SNNPRDM2BB06SNSPRDM2BB06SVNPRDM2BB06SVYPRDM2BB16KNNPRDM2BB16KNSPRDM2BB16KVSPRDM2BB16SNNPRDM2BB16SVYPRDM2BB21KNNPRDM2BB21KNSPRDM2BB21KVNPRDM2BB21KVSPRDM2BB21SNGPRDM2BB21SNNPRDM2BB21SNSPRDM2BB35SNSPRDM2PP01KNNPRDM2PP01LVGPRDM2PP01SNNPRDM2PP01SNSPRDM2PP01SVNPRDM2PP01SVSPRDM2PP02KNNPRDM2PP02KNSPRDM2PP02KVNPRDM2PP02KVSPRDM2PP02LNMPRDM2PP02LNNPRDM2PP02LVNPRDM2PP02SNGPRDM2PP02SNMPRDM2PP02SNNPRDM2PP02SNSPRDM2PP02SVYPRDM2PP06KNNPRDM2PP06KVNPRDM2PP06LNGPRDM2PP06LNNPRDM2PP06LNSPRDM2PP06LNYPRDM2PP06LVSPRDM2PP06SNGPRDM2PP06SNMPRDM2PP06SNNPRDM2PP06SVNPRDM2PP16KNGPRDM2PP16KNNPRDM2PP16KVNPRDM2PP16LNNPRDM2PP16LVNPRDM2PP16SNMPRDM2PP16SNNPRDM2PP16SVYPRDM2PP21KNGPRDM2PP21KNNPRDM2PP21LNNPRDM2PP21LVNPRDM2PP21SNMPRDM2PP21SVYPRDM2PP35KNNPRDM2PP35KNSPRDM2PP35SNNPRDM2PP35SVSPRDM3AA10LVMPRDM3AA10SVSPRDM3AA15KVGPRDM3AA15KVNPRDM3AA15LVNPRDM3AA15LVSPRDM3AA15SVNPRDM3AA15SVSPRDM3AA21SNNPRDM3AA21SNSPRDM3AA21SVNPRDM3AA21SVSPRDM3BB05SVSPRDM3BB10LNNPRDM3BB10SNSPRDM3BB10SVSPRDM3BB15KVGPRDM3BB16LNGPRDM3BB21SNNPRDM3BB21SNSPRDM3BB21SVNPRDM3PP05SNSPRDM3PP05SVSPRDM3PP10SNNPRDM3PP10SNSPRDM3PP10SVNPRDM3PP10SVSPRDM3PP15KVGPRDM3PP15LNNPRDM3PP15LNSPRDM3PP15LVNPRDM3PP15LVSPRDM3PP15SNMPRDM3PP15SNNPRDM3PP15SNSPRDM3PP15SVNPRDM3PP15SVSPRDM3PP21LNNPRDM3PP21LVSPRDM3PP21SNN)
