Overview
The DJ61Y low-temperature globe valve has two types of packing seals: double packing and single packing, which can be used in different situations. Double packing can effectively prevent cold loss, thereby enhancing the sealing effect, ensuring that the medium does not leak out, and keeping the handwheel at room temperature for flexible opening and closing.
Product Details
Product Usage and Characteristics
Low temperature shut-off valveMainly used for cutting off or connecting liquid oxygen, liquid nitrogen and other media in pipeline systems at low temperatures. The characteristics of this series of products are:
① The flow channel of the valve is a large arc transition streamline, which reduces the resistance of the medium in the flow channel;
② There are two forms of packing sealing: double packing and single packing, which can be used in different situations. Double packing can effectively prevent cold loss, thereby enhancing the sealing effect, ensuring that the medium does not leak out, and keeping the handwheel at room temperature for flexible opening and closing.
③Low temperature shut-off valveA management system suitable for low-temperature liquid storage equipment, characterized by flexible switching and reliable sealing, and can also be used for management systems of other low-temperature and cryogenic media.
