                        DZ40Y法兰低温闸阀产品简介:

                        产品:法兰低温闸阀

                        低温闸阀适用于甲烷、液态天然气、已烯、二氧化碳、液氨、液氧、液氮、液氢等低温介质。

                        产品特点

                        1、为防止中腔异常升压,在闸板的进口侧设置了泄压孔

                        2、根据阀门的工作温度确定阀盖的顶部长度,确保阀?填料的可靠密封

                        3、根据工作温度合理选用填料,垫片等零件的材料

                        4、严格控制材料的化学成份及低温冲击韧性等力学性能指标

                        5、采用多种配管法兰标准及密封面型式,适用于各种工程需要

                        二、执行标准:
