Stainless Steel Sanitary Welded Manual Butterfly Valve with Lever Handle
The stainless steel sanitary welded manual butterfly valve with a lever handle is designed to provide more precise and stable flow control, especially in pipeline systems where fluid regulation is frequent and high operating force is required. Through the handle with a lever, the operator can easily control the opening and closing of the valve under large flow and high pressure environments. This design is particularly suitable for industries that require strict hygiene standards to ensure that the fluid is not contaminated during the flow process, while providing reliable sealing and flow control. The welded structure also enhances the sealing and durability of the valve, and is suitable for long-term high-frequency operation.
Working Principles
The working principle of the stainless steel sanitary welded manual butterfly valve with a lever handle is to manually operate the lever handle to rotate the connected butterfly plate in the valve body. During operation, the lever handle drives the butterfly plate to rotate, and the butterfly plate gradually rotates to a closed or open state. When opening, the plane of the butterfly plate will be parallel to the flow direction of the pipeline fluid, forming a channel through which the fluid can pass freely; when closing, the butterfly plate rotates to a vertical position, completely closing the pipeline and cutting off the fluid flow. Through this simple and efficient manual operation, users can accurately adjust the flow or achieve emergency closure.
The options of the stainless steel sanitary welded manual butterfly valve with a lever handle include:
Material: 304 or 316L stainless steel.
Sealing material: fluororubber, silicone, PTFE, etc.
Connection method: welding, flange connection.
Handle type: lever, handwheel, lever.
Valve plate design: flat plate, butterfly type, etc.
Surface treatment: polishing, sandblasting, pickling.
