Features
The FAF3590 butterfly valve with monitoring switch is installed on the vertical axis of the pipeline, a quarter-turn (90 degree) operating disc, maintains 100% tightness in both directions thanks to EPDM embedded in the inner walls of the valve body. Pressure loss is minimal thanks to the double-shaft design. One-piece disc/stem design. The disc edge is spherically machined and hand-polished to produce a bubble-tight seal, minimum torque and longer service life. The disc/stem design inherently offers complete protection against particle entrapment and bacterial decay, protection required for sanitary performance.
