Portable Valve Actuators
JA73 Electric battery powered
Instruction manual
Light, powerful and fast, modec PVAs (Portable Valve Actuators) offer improved safety and comfort for operators
and protect equipment from damage. They can work with all types of hand wheels, keys and valves, and have a
torque that can reach up to 1000Nm.
They come with a large number of options, adaptors and accessories to best meet the particularities of different
manoeuvring systems and their environment.
Thanks to its robustness and high autonomy batteries, the JA73 modec electric portable valve actuator is able to
deliver a high power for more than one hour continuously. It does not depend on any energy source (electric plug
or compressed air network) and can operate freely anywhere. Much more powerful than its little brother (MC89),
it can deliver high speed and high torque simultaneously, which makes it the perfect tool for Heavy duty jobs.
Extremely robust, it has got an integrated clutch system which protects the operator and the equipment, even if
a valve is completely blocked.
The smart ergonomic control handle allows the display and control of the many actuator and battery's functions
and parameters in a simple and intuitive way. The integrated electronic torque limiter allows adapting to any
configuration and further improve the safety of the user and the equipment.
CAREFULLY READ THE OPERATING HANDBOOK BEFORE USE

b. Accuracy
The above values accuracy is +/- 15%.
When using the actuator at full speed up to the torque limit, the running system inertia may increase the stall torque by
15% (for the high torque and low speed settings) and up to 300% (for high speed and low torque settings). It is thus
necessary, in order to improve the torque limit accuracy, to slow the actuator when coming close to the limit required.
c. Use with a « Banjo head »
With some of the references, the use of a Banjo head can be restricted. The standard duty Banjo head (BJH01) can only
accept a 150 Nm max input torque (for a 600 Nm output torque) and the heavy duty Banjo head (BJH02) can only accept a
330 Nm max input torque (for a 1000 Nm output torque)
As a consequence, some settings are forbidden (as indicated in the tables above) as they could lead to a break of the Banjo
heads.
6. Setting up the Portable Valve Actuator
a. General info
The actuator must be kept stable while turning the valve or hand wheel.
modec Portable Valve Actuators can be used in any position. However, to ensure the operator is working safely and
in the best conditions, it is imperative that the actuator is used in the axis of the hand wheel being activated.

b. Fixing the actuator on to the torque management device and/or on an adaptor
To ensure the operator is working safely and in optimum conditions, it is imperative to use a torque retention system.
Our actuators are delivered with:
A BR001 torque management reaction bar
A strap or a chain
2 carabiners
In addition to this basic pack, modec also has a wide range of torque management accessories (see the catalogue and the
following presentation for more details).
As well as these standard accessories, modec develops specific systems. If you would like to check your installation or if you
have a specific solution request, contact a registered modec distributor.
The modec standard flange and shaft can also accommodate some specific drive heads like the Banjo heads (for handwheels
with a rising stem, or simply in order to increase the torque) or a right angle head (for a better operator position during
operation). These heads also have a torque reaction system (torque retention arm, strap and carabiners).
If this standard equipment does not provide a
torque retention that offers sufficient safety for
both operators and equipment, modec can
develop and/or adapt special torque management
systems.
Never use a portable actuator with a torque management system that is under-sized, unstable or badly
positioned
c. Fixing the BR001 torque management arm and anchoring strap
Pull each fixation spring with the ring and rotate for a quarter turn so that they stay in the pulled position.
Place the black ring of the torque management bar on the flange so that the 6 pins enter the corresponding holes.
Make a quarter turn with the fixation springs rings and release the springs making sure they come back.
Check that the torque management bar is properly secured to the flange.

7. Using the actuator
a. Preliminary checks
1. Check the equipment is in good condition and use accessories that are the most suitable for the actuator.
2. Make sure the torque management system and the handwheel adapter are compatible with the action about to be
carried out.
3. Connect the battery to the actuator with the adequate connection cables.

4. Press the battery switch on “I”
5. Switch on the actuators. The smart handle screen identifies it and displays its name.
6. Set power to minimum
7. Check the rotation direction required for the valve, indicated on the handwheel or the manual. Set the defined rotation
direction on the handle.
8. Position the adaptor on the valve and set up the torque retention system. Consult the instructions for adaptors.
When starting up always start slowly in order to CHECK the rotation direction, and to gently apply tension on the torque
retention strap or chain.

Unlock security by pressing the safety trigger (1) and accelerate progressively (2).
The actuator is equipped with a clutch.
When accelerating, the motor runs before engaging the gearbox and output shaft.
This shift process is normal.
b. Potential problems when actuating a valve
1 –If the valve does not move, release the handle and change the actuator’s rotational direction to give it a little nudge.
Check again the direction of the torque retention.
2 –If there is increased resistance from the valve the torque applied to the actuator will increase, the actuator will slow down
and will eventually stall when the maximum torque it can face is reached. Be very careful that the applied torque does not
exceed the limits the valve can withstand, or use the torque limiter.
3 –In case of resistance resulting from deposits on the stem, turn the valve in both directions several times to ‘clean’ it.
modec revolution counter (optional) enables you to always know which position the valve is in.
4 –When the closed position is reached, make sure the torque does not exceed the level that the valve can withstand. Unless
the procedure indicates otherwise, reopen the valve with a few turns so that the accelerated fluid “cleans” any potential
impurities from the valve, then close it again at the desired torque.
5 –When the maximum open position is reached, reclose with a few turns to avoid the valve being stuck in future. Doing this
also means that the valve is still able to turn when next actuated even if the operator turns it the wrong way, which again
helps prevent the valve being stuck.
Take note - the torque when closing a valve should always be less than the torque when opening a valve, in order to
guarantee that the valve can be reopened. Using the torque limiter for closing and opening a valve means you can be
always be sure to have enough torque in reserve for the valve to be reopened or reclosed.

8. Options
a. Digital Revolution counter
PRESENTATION
The digital Revolution counter adds up the revolutions in
one direction and subtracts them in the other direction in
such a way that the operator always knows the valve position
compare to the initial status. The tool also measures and
displays the rotational speed.
Nota 1 : The instant speed indicator needs several revolutions
before it can give a stable and accurate speed. In light of this,
you have to wait several seconds to get a reliable reading.
Nota 2 : The screen turns itself off after 5 minutes.
HOW IT WORKS

REVOLUTION COUNTER PARAMETERS
The revolution counter is set by default for a straight or right angle head standard output shaft (STD), without Banjo head.

General recommandations
-Take note of all the work health and safety regulatory provisions that apply and any local workplace safety instructions
including conditions relating to the work environment, clothing and the operator’s individual protective equipment as
required by all the applicable regulations.
-It is advisable to keep a maintenance log for all maintenance tasks carried out on the actuator.
-Prevent foreign bodies from entering the system by using a clean work surface in order to protect the delicate moving
parts from being contaminated by dirt or foreign materials when assembling and dissembling, as this could cause a
deterioration of the mechanical parts.
-Maintenance of the Portable Valve Actuators should be carried out by people who have been trained by modec.
-Our “After Sales Service” department are ready to help in this respect.
-Systematically take out the spark plug before carrying out any procedure that involves replacing, adjusting, servicing
or dissembling the actuator or any of its parts.
-Every time maintenance is carried out, test the actuator afterwards to check it is working correctly.
-Only use approved replacement parts and follow the manufacturer’s advice with regard to lubrication and
waterproofing.
