360 degree rotating butterfly valve

Brand：Yibiao 型號：SZDF

360度旋轉蝶閥is a specially designed butterfly valve type, whose core feature is that the valve stem and disc can achieve 360 degree continuous rotation, thereby expanding the operating range of traditional butterfly valves with 90 degree opening and closing.

The following are the key technical features and application analysis of rotary butterfly valves:
1、 Structural design features
Rotational degrees of freedom
By optimizing the connection between the valve stem and the valve disc (such as replacing traditional pin connections with pull-out pin structures), the valve disc can rotate continuously 360 degrees around the axis, achieving multi angle adjustment or cyclic switching functions. Some models are equipped with special worm gearboxes or actuators that support full rotation operation.
Sealing form
Adopting elastic sealing rings (such as EPDM, NBR) or metal hard sealing design, supporting bidirectional sealing. Some products enhance their sealing performance under reverse pressure through a self sealing structure.
2、 Performance advantages
Operational flexibility
The 360 degree rotation characteristic allows the valve to adjust the flow direction of the medium in the open state, which is suitable for working conditions that require frequent reversing or diversion (such as powder conveying, gas-liquid mixing systems).
Application adaptability
Industrial scenario: commonly used for powder material sorting and unloading (such as cement and chemical raw material processing), supporting multi pipeline switching.
Special media: The stainless steel material version can be used for corrosive media (such as liquefied gas, nitrogen) and sanitary requirements scenarios (in the food and pharmaceutical industries).
3、 Typical application scenarios
Typical model examples for specific purposes in application fields
Powder conveying system with multiple pipelines for material separation and quantitative discharge D671X-16P (pneumatic type)
Chemical process corrosive medium diversion control DN200 clamp quick installation valve
Food/pharmaceutical sterile environment medium switching sanitary grade stainless steel butterfly valve
4、 Selection precautions
Drive mode selection: Pneumatic type has fast response but requires air source, while electric type is suitable for remote control.
Sealing requirements: Metal hard seals are preferred for high temperature and high pressure working conditions, and must comply with FDA certification in the sanitary field.
Installation space: The clamp type structure is compact, but it is necessary to ensure that the flange spacing of the pipeline meets the standard.
This type of valve expands the functional boundaries of traditional butterfly valves through rotational degrees of freedom, but requires matching sealing materials and driving methods according to specific operating conditions to ensure long-term reliability.
