Applications:
Water, foodstuffs and many corrosive media, subject to compatibility
with wetted parts in contact with media.
Electrical actuators sized on a maximum differential pressure of 10
bar wet service, operated at least once per day. If the intended duty
differs from these parameters or is dry (air or gas), call to check JJ
actuator sizing as a larger output valve actuator may be required.
Maximum working temperature of a direct mounted assembly is
+70C. For higher working temperatures , consider models that have a
mounting kit between the valve and actuator which uses air cooling
to dissipate the rising heat from the valve away from the actuator.
Should the J3 smart actuator see more than +70C it will malfunction.

How this electric 1/4 turn valve works (on-off):
Electrically operated valves are driven by a motor and gearbox.
On receipt of a continuous voltage signal the motor runs and,
via a gearbox in the J+J smart electric actuator, rotates the valve
stem. The motor stops at the desired position (usually 0° or 90°)
by internal cams striking micro-switches. The smart valve actuator remains in this position, with the voltage still applied continuously, until switched and a continuous voltage reversing signal
is applied, which runs the motor in the opposite direction, reversing the rotation until separate set of internal cams strike
separate set of micro-switches.

Wafer pattern butterfly valve installation information:
Wafer pattern butterfly valves sandwich between two mating flanges,
secured by through bolts that pass all the way from one flange to the
other, and a corresponding nut. See diagram to the right.
The correct alignment of wafer pattern valve so that the butterfly
valve’s resilient liner seals against the raised faces of the flanges is
aided by through-bolt lugs cast into the wafer valve’s body, although
as these lugs are oval in shape to allow alignment with several different flange standards (ANSI, BS, DIN), care must be taken to ensure
correct alignment when tightening the through bolts.
Wafer butterfly valves are not suitable for end of line service.
