J2
-20 IP65 Electric Actuator
J2
The maintenance free electric actuator is very user friendly. It offers more standard features than any
rivals in its class, and was first to the market with both multi-voltage capability with automatic voltage sens-
ing, and an electronic torque limiter with auto-gearbox relaxing which frees the manual override when a
valve is jammed. The manual override facility, with a safety power cut-out switch when operated, allows
safe hand operation .
Time saving external DIN plugs allow installations to be pre-wired and eliminates the need to remove the
cover to connect the actuator, which helps to reduce installation costs.
With a soft start system eliminating high motor start loads and a thermostatic anti-condensation heater
that does not require a separate connection, the
The IP65 weatherproof plastic housing with stainless steel cover screws offers excellent corrosion resis-
tance.
Local visual position indication and remote volt free end of
travel confirmation are provided as standard.

The is quick and easy to install:
a) ISO:5211 multi-flange F03/F04 or F05 mounting with a
14mm female double square (star) drive.
b) Factory set open and closed positions at 0 and 90° (or
as specified on your order).
c) External electrical connections and external wiring
diagram- no need to remove the cover to connect.
Note: Always read the supplied installation & operating instructions before use.

-Model 20 Options
Battery 'Spring Return' (BSR)
Power open, power to close,
fails safe on power failure. Uses
an industrial rechargeable bat-
tery-back up system. Can be
used as energize open, fail
close, subject to minimum
energize open time.
See individual datasheet for
more information.
Model 20
J2 offers low power consumption.
Digital Positioning System (DPS)
Internally factory fitted Digital
Positioning System (DPS) pro-
vides accurate modulating func-
tion with either 0-10VDC or
4-20mA control signal. Output
signal provided.
See individual datasheet for more
information.
Mounting Kit Options
ISO:5211 multi-flange mounting
offers F03/F04 & F05 fixings
with a 14mm double square
female (star) drive.
A full range of stainless steel
mounting kits are available,
typically for non-direct mount
valves and for elevated tem-
perature applications.
