Introduction

Sanitary butterfly valves are essential components in industries requiring high levels of hygiene and cleanliness. These valves are critical in processes where contamination is a primary concern, such as in food processing, pharmaceuticals, and biotechnology sectors.

What is a Sanitary Butterfly Valve?

A sanitary butterfly valve is a type of flow control device that utilizes a rotational disc to regulate the flow of fluids within a pipeline. The disc is positioned in the center of the pipe, and a rod passes through the disc to an actuator situated outside the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow of the fluid, thus regulating its passage.

Applications of Sanitary Butterfly Valves

Sanitary butterfly valves are often used in industries where cleanliness is a paramount concern. Common applications include:

• Food and beverage processing
• Dairy industry
• Pharmaceutical manufacturing
• Biotechnology
• Brewing and distilling

Design and Material Specifications

Sanitary butterfly valves are designed to meet strict hygienic standards. They are typically made from stainless steel grades such as 304 and 316, known for their corrosion resistance and durability. The valve seats and seals are crafted from materials like PTFE or EPDM to withstand various fluid compositions and temperatures.

Operational Parameters

These valves function efficiently under specific operational conditions. Key parameters include:

• Operating Pressure: Generally up to 16 bar (232 psi)
• Temperature Range: -10°C to 150°C (14°F to 302°F) depending on the material
• Size Range: Commonly from 1 inch to 12 inches in diameter
• Flow Control: Precise modulation due to the 90-degree rotational capacity of the disc

Advantages of Sanitary Butterfly Valves

These valves offer numerous benefits, including:

• Compact design and easy installation
• Quick opening and closing mechanism
• Low maintenance and easy cleaning
• Cost-effectiveness due to simpler design compared to other valve types
