High Performance
Butterfly Valve

High Performance double-eccentric PTFE-seat stainless steel butterfly valve

The High-Performance Butterfly Valve is a versatile and reliable solution for critical industrial applications, offering outstanding sealing, easy operation, and long-term durability. Its advanced features make it the ideal choice for challenging conditions requiring precision and dependability.

The main difference from classical double- and triple-offset  butterfly valves lies in the choice of improved sealing materials.

Features & Benefits

Bidirectional Zero-Leakage Sealing: Ensures flawless sealing under both directions, proven by rigorous testing.

Minimal Flow Resistance: Low medium retention in the pipeline reduces resistance, making it suitable for powders and viscous media.

Compact and Lightweight Design: A simple structure with small dimensions, light weight, and low torque ensures smooth and flexible operation.

Adjustable Sealing Compression: Allows fine-tuning of the sealing ring's compression to achieve optimal sealing effectiveness.

Versatile Application: Wide compatibility with diverse working conditions and media due to advanced sealing materials.

Ease of Maintenance: Designed for easy disassembly, repair, and flexible installation in any orientation.
