EBF01-TF02-Operation and Maintenance Manual DOWNLOAD

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.
