Applications:
Valve seats
PTFE
Potable water, oil, air and most non-corrosive media, subject to
compatibility with wetted parts in contact with media. This assembly
is NOT recommended for use on steam.
Valve Pressure rating
UTI 2” 40 bar at ambient temp
Valve temp limits
-20 to +95°C
Valve 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), please call to
check the actuator sizing as a larger output electric actuator may be
required.
Size range
1/2” to 2”
Maximum working temperature of a direct mounted assembly is
+70C. For higher working temperatures , consider models that have
a mounting kit or TSM stem extension between the valve and the JJ
electric 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.
Ball valve information:
Full bore 2 piece construction, providing full unrestricted flow
and a very low pressure drop across the valve. Approved in the
UK for use on potable water by WRAS. Designed for automation
with integrally cast ISO5211 actuator mounting platform. Turning
the ball through 90° fully opens the valve, turning back through
90° fully closes the valve and isolates the flow. End connections
are threaded BSP female.
Uncontrolled copy, not subject to automatic updates.
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
