Cr-Ni-Ti Steel Cryogenic Jacketed Globe Valve

The opening and closing parts of BJ41H jacketed insulation globe valve are plug-shaped disc, and the sealing surface is flat or conical, and the disc moves linearly along the center line of the valve seat. The opening or closing stroke of the stop valve stem is relatively short, and it has cutting action, which makes it suitable for cutting off or adjusting the medium and throttling. Jacket insulation globe valve belongs to forced sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface not to leak. After the appearance of the self-sealing valve, the medium flow direction of the cut-off valve is changed from above the disc to the valve cavity. At this time, under the action of medium pressure, the force of closing the valve is small, while the force of opening the valve is large, and the diameter of the valve stem can be reduced accordingly. At the same time, under the action of medium, this type of valve is also tight. The insulation jacket of the jacket insulation stop valve is welded between the two flanges of the valve, and the side and bottom of the valve are provided with two connection ports of the insulation jacket. Jacket insulation cut-off valve is suitable for pipelines in chemical and fertilizer industries, and the jacket contains steam energy to avoid medium crystallization. Jacket insulation globe valves are used in petroleum, chemical, metallurgical and other systems. Performance characteristics of BJ41H jacketed insulation globe valve 1, simple structure and convenient maintenance; 2, the working stroke is small and the opening and closing time is short; 3, good sealing performance, small friction between sealing surfaces and long service life; 4. Suitable for medium with high viscosity and easy coking.Technical parameters and characteristics:Product typeSwitch ValveProduct descriptionGlobe valveModelDJ41SizeNPS 2"~24"(DN50~DN600)Operating temperature -46ºC~593ºCACC to materialOperating pressureCLASS 150~2500 (PN 20~PN420)MaterialA216 WCB,WCC; A217 WC6,WC9,C5,C12,C12A,CA15; A351 CF8,CF8M,CF3,CF3M,CF8C,CN3MN,CK3MCUN,CN7M;A352 LCB,LCC; A494 CW-6MC,CU5MCuC,M35-1; A890 4A(CD3MN),5A(CE3MN),6A(CD3MWCuN); ASME B 148 C95800,C95500 .etcStandardAPI 623,BS 1873 ,ASME B16.34Face to faceASME B16.10Connecting endASME B16.5,ASME B16.25Test standardAPI 598,ISO 5208Operationhandwheel, worm wheel ,electric ,pneumaticApplication fieldselectric power industry, petroleum refining, petrochemical industry, offshore oil, chemical industry and etcSeal material13Cr , STLOther remark 1The disc shape including: tapered, needle type, spheroidal, parabola, apply to adjust the flow.  /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
