hafner solenoid valve What brand

Hafner-Pneumatik (Germany) Hafner) is a professional manufacturer with more than 40 years of experience in pneumatic product development. It adheres to the purpose of producing a full range of high-quality, high-performance products, and its product production and research and development concepts for the purpose of cooperating with the development of high-level industrial automation enable today's Hafner to It flexibly adapts to the market, actively responds to customer needs, and continuously launches products of excellent quality;its strict insistence on rigorous design, quality first market concept and its low product pricing are also widely favored by the market, all of which have won Hafner a large number of customers. A solid foundation was laid.

hafner was successfully applied to the process Control, petrochemical, electric power, railway transportation and other important fields. Its independently developed patented sealing system - "free seal", which is a solution for Solenoid valve has made outstanding contributions to the service life of The samples of hafner's "free seal" system have undergone more than 50 million trouble-free and maintenance-free switch tests, and the unique low-temperature resistant series products are also widely used in polar deep cold fields, and can adapt to -50° C environment application.

hafner solenoid valve features and advantages

Due to the use of high-quality materials and approved sealing systems, the advantages of the products we offer our customers are It is obvious that HAFNER will not compromise on low-cost materials in the selection of raw materials;the valve body is made of high-quality anodized aluminum alloy, the valve core is made of stainless steel, and the manual reset device is made of brass.

The sealing concept of hafner valve is:Low friction .

These advantages mainly come from the following product technical features:

The sealing rings used to seal the valve core will not have any deformation after being assembled on the valve. These sealing rings can be fixed on the valve body on the brass Swimming in the trench. Without air pressure there is no contact pressure and therefore no wear. This structure also affects the valve in use. When a 5-position 2-way valve is opened, only 3 of the 5 sealing rings will be under pressure and cause friction with the valve core.

This unique seal The principle means that the sealing effect of the sealing ring is proportional to the air pressure. The greater the air pressure, the better the sealing effect;of course, if the air pressure is relatively low, the contact pressure of the valve core will be smaller, and the friction will be smaller.

Even when the air pressure is very high When the sealing ring swims in the defined brass groove, the impact of the contact pressure on the sealing ring is very limited, and the part contacted by the sealing ring only provides the minimum contact part for sealing the valve core. .

These features provide you with the following advantages:

Durability, long life!

Large flow, small size!

Reliability, low cost!
