Product Overview

What is a Vacuum Butterfly Valve?

A Vacuum Butterfly Valve is a quarter-turn rotary valve designed specifically for vacuum pipeline systems. Unlike conventional butterfly valves used for positive pressure systems, vacuum variants are engineered with specialized sealing arrangements and leak-tight construction to maintain controlled vacuum levels without air ingress.

The valve consists of a circular disc mounted on a rotating shaft inside a cylindrical body. When rotated 90 degrees, the disc allows or restricts flow. The sealing surface is optimized to ensure minimal leakage under vacuum conditions.

Design Construction

• Valve Body – Cast Iron / Cast Steel / Stainless Steel
• Disc – SS 304 / SS 316 / SS 316L
• Seat – EPDM / NBR / Viton / PTFE (Vacuum Grade)
• Shaft – Stainless Steel
• Operation – Manual Lever / Gear Operated / Pneumatic Actuator

Available Sizes

DN 50 mm to DN 600 mm (Custom sizes available on request)

Pressure & Vacuum Rating

Suitable for high vacuum applications with leak-tight performance.
