What is the working principle of stainless steel sanitary butterfly valve?


Stainless Steel Sanitary Tri Clamp Manual Butterfly Valves


Sanitary butterfly valves, also known as sanitary clamp butterfly valves, are widely popular flow control devices with high practicability in the food, biotechnology and pharmaceutical industries. In simple terms, it is similar to a mechanical switch, with the ability to close/open pipes and control the amount of material passing through them. There are different types of butterfly valves, each suitable for a different pressure and service. Zero eccentric butterfly valve has rubber flexibility and lowest rated pressure. High performance double eccentric butterfly valves (for slightly higher pressure systems) offset the center line of the disc seat and body seals and the center line of the hole (two off center). This creates cams during operation to lift the seat from the seal, creating less friction and reducing wear trends compared to the original offset design.

 

The body, disc and other components of the sanitary valve are made of stainless steel. Its stainless steel is located in the center of the pipe. The disc consists of top and bottom rods connected to a handle or actuator on the valve body. The seat is in the shape of a rubber ring between the body and the butterfly. When turning the handle, it also turns the disc parallel or perpendicular to its direction of flow. Valve openings have specific pipe diameters to allow free flow of fluid when the valve is open. A sanitary butterfly valve is rather similar to a quarter - turn valve. The quarter valve can be opened or closed when the handle is rotated 90 degrees. Also known as a "butterfly", the torque of the metal disc depends on whether the valve is partially closed or fully open or closed. If the valve is partially open, this means that the disc does not provide unlimited access. On the other hand, if it is fully opened, fluid or air can pass through. It is designed in multiple locations so that the valve can be opened slowly to reduce pressure on the equipment. The seal may be affected by disc compression against the internal parts of the rubber seal. Sealing materials include EPDM, Viton and Silicone, with sizes ranging from 1 "to 4". The configuration of each butterfly health valve is different. There are few manual operations, while others are automated. They vary in style, with only a few providing high performance in systems such as large pump lines and front areas.

 

What are the salient features of the sanitary butterfly valve?


1. The stainless steel sanitary butterfly valve's full bore design helps prevent the flow of solid components such as particles, powders and similar materials.


2. Because the surface of the valve is stainless steel and smooth, it is highly resistant to corrosion. The health grade valve helps to save money on changes to retrograde and village valves.


3. They are also easy to clean because their surfaces have been polished, eliminating the chore of regular cleaning.


4. The automation of sanitary valves can be easily achieved by using two rack and pinion pneumatic actuators. Manufacturers offer different switch packs to install into their actuator ranges.


5. It has the characteristics of simple structure, small volume, light weight and small installation space. Even the driving torque is small, simple and fast.


6. It is important to know that butterfly valves have clamped ends so that they can be easily installed or removed when cleaning or working in a narrow space. This is a special design to minimize turbulence and maximum flow.


7. They have no water hammer and are not sensitive to the pressure shock of the pipe.

 

What should I pay attention to when buying sanitary butterfly valves?


Valves designed for these industries require a high level of attention to specifications such as pressure, breaking torque, flow coefficient, temperature, and standard diameter and weight. One should use the details to cover the maximum functionality required for each customer's requirements. Valve manufacturers recognize the need to customize valves for their customers and to design high-quality materials that work effectively in all environments. These sanitary butterfly valves can be started manually or automatically by using electricity. Sanitary clamp butterfly valves are manufactured in a variety of designs and models to serve different purposes and bring maximum benefits to users.

 

It is recommended to purchase sanitary butterfly valves from a government approved, certified manufacturer who is active in the industry and has many years of experience available to many customers. Also, make sure that all tools, accessories, and fixtures are tested before purchasing to ensure that you get the best product with zero problems. Professional manufacturers will provide regular repair and maintenance to keep the products in effective operation. The product should be thoroughly inspected and the surface should be effectively polished to reflect a bright surface. It is essential that valves operate efficiently, smoothly and error-free. When manufacturing valves, always ensure that all requirements and standards are met.
