D343H/Y High Temp And High Pressure Hard Seal Butterfly Valve product details

D343H/Y High Temp And High Pressure Hard Seal Butterfly Valve Scope of application
D343H/Y High Temp And High Pressure Hard Seal Butterfly Valve produced and sold by Baigang valve group is suitable for high school low pressure, high temperature, low temperature pipe for closed circuit sealing device, throttling device and regulating device. Widely used in petroleum, chemical, metallurgy, mining, electricity, energy, transportation, farmland, water, construction and other industries. Particularly suitable for more stringent sealing conditions, such as gas pipelines, but also for water, steam, oil, air, electricity, dust, nitric acid and other corrosive media.

D343H/Y High Temp And High Pressure Hard Seal Butterfly Valve Structural characteristics
Two-way metal sealing butterfly valve is based on the introduction of foreign advanced technology, improved and perfected, the use of precision elastic ring and polished disc contact, widely used in metallurgy, petrochemical, air As well as plumbing and municipal construction and other industrial piping for the regulation and closure devices.
1, the structure of short size, small size, light weight, easy operation;
2, using the axle structure, disc truss structure, high strength, flow area, small flow resistance, energy saving;
3, eccentric structure, to achieve The disc is opened at the moment that is separated, the effect of closing the contact is sealed to achieve the purpose of extending life expectancy, sealing performance;
4, the sealing surface made of stainless steel, with metal seal and elastic seal dual advantages, both in the case of low temperature and high temperature , Have excellent sealing performance, corrosion resistance, long life characteristics;
5, with two-way sealing function, the installation is not limited by the flow of media (if only one-way control of media, should be favored in favor of sealing Installation direction installation), but also the location of space, can be installed in any direction.
