Product Advantage of worm gear wafer bfv valve

Replaceable EPDM Seat – The EPDM seat can be removed and replaced without replacing the entire valve, helping reduce maintenance costs and downtime.
CF8 Stainless Steel Disc – The CF8 disc provides good corrosion resistance and mechanical strength for water and general industrial services.
Reliable Sealing – The resilient EPDM seat provides tight shut-off and helps maintain sealing performance through repeated operation.
Low Operating Torque – The concentric butterfly valve design minimizes friction between the disc and seat, supporting smooth operation and efficient actuator sizing.
Flexible Actuation – Suitable for manual operation with a lever or gearbox, as well as pneumatic or electric actuators for automated systems.
Easy Maintenance – The replaceable-seat construction simplifies maintenance and allows the sealing component to be renewed when required.
Double Shaft Design – The disc is securely connected to the upper and lower shafts, providing stable disc support and reliable torque transmission during valve operation.
Upper and Lower Shaft Connection disc- features protrusions at the top and bottom to accommodate the valve stem, while the central section is flat, thereby reducing head loss.
