I-FLOW EN 593 Butterfly Valve

What is an EN 593 Butterfly Valve?

The EN 593 Butterfly Valve refers to valves that comply with the European standard EN 593, which defines specifications for double-flanged, lug-type, and wafer-type butterfly valves used for isolating or regulating the flow of liquids. These valves are designed for easy operation, quick opening and closing, and are well-suited for systems requiring high flow rates.

How Does a Butterfly Valve Work?

A butterfly valve consists of a rotating disc, known as the butterfly, which controls the flow of fluid through a pipe. When the disc is rotated a quarter-turn (90 degrees), it opens fully to allow maximum flow or closes to stop flow completely. Partial rotation enables flow regulation, making these valves ideal for throttling or flow isolation.

Key Features of IFLOW EN 593 Butterfly Valves

Compliance with EN 593 Standard: These valves are manufactured to comply with the EN 593 standard, ensuring they meet strict European regulations for performance, safety, and durability.

Versatile Design: Available in wafer, lug, and double-flanged configurations, I-FLOW butterfly valves offer flexibility to suit various pipeline configurations and operational needs.

High-Quality Materials: Constructed from corrosion-resistant materials like ductile iron, stainless steel, and carbon steel, these valves ensure long-lasting performance even in corrosive or harsh environments.

Soft or Metal Seats: The valves are available with both soft and metal seat designs, allowing for tight sealing in low and high-pressure applications.

Low Torque Operation: The valve’s design allows for easy manual or automated operation with minimal torque, reducing energy consumption and wear on the actuator.

Spline Shaft Technology: The Spline Shaft ensures smooth operation, allowing for more precise control and reducing wear on the internal components. This contributes to the valve’s extended service life, making it a cost-effective solution for long-term use.

Butterfly Plate Structure: The butterfly plate enables rapid opening and closing operations, making the valve ideal for controlling fluid media. It’s especially useful in applications requiring quick shutoff and efficient flow regulation.

Benefits of I-FLOW EN 593 Butterfly Valves

Quick and Easy Operation: The quarter-turn mechanism ensures rapid opening and closing, making these valves suitable for emergency shutoff scenarios.

Cost-Effective Flow Control: Butterfly valves provide an economical solution for flow regulation and isolation in large pipeline systems.

Minimal Maintenance: With fewer moving parts and a streamlined design, butterfly valves require less maintenance compared to other valve types, reducing downtime and operational costs.

Compact and Lightweight: The compact design of butterfly valves makes them easier to install and handle in tight spaces compared to other types of valves, such as gate or globe valves.
