Butterfly Valves

Butterfly valves offered by ORFA Industrial provide high efficiency in industrial fluid control systems with their compact structure, low pressure drop, and fast opening and closing in a quarter turn. Thanks to their lightweight body design, both installation and maintenance processes are practical and economical.

Butterfly Valves: Description and Operating Principle

A butterfly valve is a type of valve that operates by a circular disc placed inside the pipeline rotating around its own axis. Flow control is achieved by rotating the disc 90° using a shaft.

• Open Position: The disk is parallel to the direction of flow, and flow is free.
• Closed Position: The disc is perpendicular to the flow direction, and the line is completely closed.

Advantages of Butterfly Valves

• Lightweight and compact design
• Energy efficiency with low pressure loss.
• Quick on/off (quarter turn)
• Easy assembly and maintenance.
• Long-lasting and durable structure.

Assembly and Control Types

• Wafer Tip: Mounted by being clamped between flanges.
• Lug Tip: Secured to the line with a bolted connection.
• Control Options: Manual, geared, pneumatic, and electric actuator.

Areas of Application

Butterfly valves are reliably used in a very wide range of industrial applications:

• Water and wastewater treatment plants
• HVAC systems
• power plants
• Chemical and petrochemical plants
• Food and beverage industry
• Shipping and industrial process lines
