3 Offset Laminated Seal Butterfly Valve

◆The 3 Offset Laminated Seal Butterfly Valve is a butterfly valve with complex sealing structure and reliable performance. This kind of butterfly valve is usually composed of a valve body, valve plate, transmission device, seal, etc. Its sealing structure adopts eccentric multi-level sealing design, which has many advantages such as preventing medium leakage, light operation, stability and reliability.

First of all, the 3 Offset Laminated Seal Butterfly Valve adopts an eccentric structure design, which helps to reduce the friction and pressure loss in the use of the butterfly valve, and improves the working efficiency of the valve. Secondly, on the basis of the traditional sealing structure, the triple eccentric multi-level sealing butterfly valve also adds a sealing medium inlet, which can enter the low-pressure, high-pressure and vacuum chambers, which further improves the sealing performance and reliability of the valve. At the same time, the butterfly valve adopts a detachable sealing ring design, which is easy to maintain and replace, and effectively prolongs the service life of the valve. In addition, there are many kinds of sealing rings for triple eccentric multi-level sealing butterfly valves, and suitable sealing rings can be selected according to the requirements of different media and working environment to ensure the sealing effect of the valve.

3 Offset Laminated Seal Butterfly Valves are mainly used in fluid control in chemical, pharmaceutical, food, liquefied gas and other fields. Its sealed design can effectively prevent media leakage and ensure the safety and stability of the production process. Easy and quick to install and operate, making the maintenance and maintenance of butterfly valves an easy job. The valve body is made of a variety of materials, such as cast iron, carbon steel, stainless steel, etc., to adapt to different media and working environments.

In short, the 3 Offset Laminated Seal Butterfly Valve is a high-performance, high-reliability sealed butterfly valve, which is widely used in fluid control in the fields of chemical, pharmaceutical, food, liquefied gas, etc., and its good sealing performance, ease of operation and stable reliability make it an irreplaceable equipment in the field of fluid control.
