Food and Wine Sanitary Stainless Steel Pneumatic Butterfly Valve
A pneumatic butterfly valve is a special type of valve that utilizes a disc as its primary closing mechanism. This design allows for effective flow control in a variety of applications. The valve is operated by a pneumatic actuator that utilizes compressed air to facilitate the opening and closing of the valve. When the actuator receives a signal, it directs compressed air to move the valve disc to the desired position, either allowing fluid to flow through the valve or blocking fluid flow entirely. This fast response time makes pneumatic butterfly valves ideal for processes that require rapid regulation of flow.
Suitable for on-off or modulating control in systems with low-pressure drop requirements.
This design is commonly used for regulating or isolating fluid flow in various industries, such as chemical, food, and pharmaceutical processing.
1. Disc Mechanism: The valve features a circular disc that rotates around an axis to allow or block fluid flow.
2. Pneumatic Actuation: Controlled by air pressure, allowing fast and efficient automation.
3. Compact Design: Generally lighter and more compact compared to other valve types like gate or globe valves.
Materials
Body Materials: AISI-304 or AISI-316L
Can be made from stainless steel, which ensures corrosion resistance and sanitary standards, especially important for industries like food, beverage, and pharmaceuticals.
6.Gasket Material:Silicon, EPDM, VITON, NBR Valve seat and gasket comply with FDA 21CFR177.2600
These valves are used in a wide range of industries including water treatment, food and beverage, pharmaceutical and chemical processing due to their reliability and ease of operation. The simple yet effective design minimizes pressure drop across the valve, ensuring efficient fluid dynamics.
Pneumatic butterfly valves can be equipped with various control systems, such as position sensors and controllers, to improve the automation and accuracy of flow management. Its compact design allows for easy installation in tight spaces, making it a versatile option for new installations and retrofits of existing systems.
Pneumatic butterfly valves stand out for their combination of efficiency, reliability, and adaptability, making them the solution of choice for many industrial applications that require precise flow control.
