Butterfly valves with hand lever
VFY-WH, VFY-LH

Description Features:

• Spline driven one piece shaft connected to
spherically machined disc allows high

torque transmission i.e. quick response and

minimum back-lash

• Long term reliability due to upper and lower
anti-friction bearings

• Safe maintenance :
shaft blow out protection with circlip

• Padlockable hand lever with 10 positions.

Installation conditions

It is recommended that distances indicated
below are respected in order to prolong lifetime
of the valve. Mounting the valve close to
pipework junctions (turbulent zones) increases
wear.
