Key Features:

1. Double Offset Eccentricity

• offset disc design reduces seat friction by 60%, extending service life.

• Anti-cavitation performance minimizes turbulence in high-velocity flows.

2. Double Flanged Robustness

• Double flange butterfly valves offer a compact and robust design for easy installation and long service life.

• They provide excellent sealing capabilities and bidirectional flow control, making them ideal for various industrial applications.

3. High-Pressure Sealing

• A PN25 rated high-pressure butterfly valve is engineered to handle demanding applications with a nominal pressure of 25 bar.

• It typically features a robust design with a double-flanged connection, a resilient seated or high-performance metal-seated disc, and a sturdy shaft to ensure reliable shut-off and control in high-pressure systems for water, oil, gas, and other industrial services.
