一、进口低温截止阀概述

进口低温截止阀，也叫LNG截止阀，液氮截止阀，液氧截止阀，液氩截止阀，液化天然气截止阀，是指用于低温液体（主要包括液氧、液氮、液氩、液态烃和液化天然气等LO2、LN2、LAR、LNG等）贮运设备的管理系统的截止阀，具有开关灵活、密封可靠的特点，也可用于其他低温和深冷介质的管理系统。

美国威盾VTON主要产品有进口低温截止阀，进口低温短袖截止阀，进口低温长袖截止阀，进口低温不锈钢截止阀，进口低温焊接截止阀，进口低温法兰截止阀，进口LNG低温截止阀，进口液氮截止阀，进口液氧截止阀，进口液化天然气截止阀，进口低温深冷截止阀等。主要用于乙烯，液化天然气装置，天然气LPG LNG储罐，接受基地及卫星站，空分设备，石油化工尾气分离设备，液氧、液氮、液氩、二氧化碳低温贮槽及槽车、变压吸附制氧等装置上。

Low temperature shut-off valve, also known as LNG shut-off valve, liquid nitrogen shut-off valve, liquid oxygen shut-off valve, liquid argon shut-off valve, liquefied natural gas shut-off valve, refers to the shut-off valve used in the management system of low-temperature liquid (mainly including liquid oxygen, liquid nitrogen, liquid argon, liquid hydrocarbons, and liquefied natural gas, such as LO2, LN2, LAR, LNG, etc.) storage and transportation equipment. It has the characteristics of flexible opening and reliable sealing, and can also be used in the management system of other low-temperature and cryogenic media.

VTON's main products include imported low-temperature globe valves, imported low-temperature short sleeved globe valves, imported low-temperature long sleeved globe valves, imported low-temperature stainless steel globe valves, imported low-temperature welded globe valves, imported low-temperature flange globe valves, imported LNG low-temperature globe valves, imported liquid nitrogen globe valves, imported liquid oxygen globe valves, imported liquefied natural gas globe valves, and imported low-temperature cryogenic globe valves. Mainly used in ethylene, liquefied natural gas equipment, natural gas LPG LNG storage tanks, receiving bases and satellite stations, air separation equipment, petrochemical tail gas separation equipment, low-temperature storage tanks and tankers for liquid oxygen, liquid nitrogen, liquid argon, carbon dioxide, and pressure swing adsorption oxygen production equipment.
