1. Design and Functions
1-1. Technical Features
① Turn the main power supply ON/OFF to open/close the valve.
• Unlike conventional electric valve actuators, only two wirings are required for the
ON-OFF operation.
② There are no problems of water hammers.
• Since the operation speed is not too fast unlike solenoid valves, there are no
problems of water hammers even if the fluid is liquid.
③ Manual operation
• It is easy to operate manually.
④ Manual lock mechanism
• Since it is equipped with the manual lock mechanism, it is possible to hold the valve
in the open status even if the power supply is turned off.

The product is not designed for explosion-proof. Do not install it in
any explosive environment to prevent accidental mishaps. Also do not
install it in any corrosive environment which will affect the service life.
Do not carry out wiring works on actuators being energized, and do not
remove covers of their housings during wiring, to eliminate the danger of
an electric shock.
Do not disassemble energized actuators from valves. It will damage
valves or actuators and cause problems.
Do not put your fingers or foreign objects such as tools into ports of
valves being fully opened or closed. It may cause injuries or equipment
damages.
Before dismantling actuated valves from piping, ensure to equalize the
piping pressure with the ambient pressure and thoroughly release line
fluid from the piping. Otherwise, residual pressure and line fluid will
dangerously extrude from valve bores.
Factory-assembled actuated valves are adequately adjusted for
satisfactory function and performance. Do not disassemble them for any
reason, unless approved in advance by KITZ Corporation, as it may cause
valve malfunction, valve seat leakage and other technical problems.
This manual covers the procedures to properly handle KITZ compact ball
valves driven by KITZ ESR Series actuators. For the product
specifications of ball valves and so on that mount this product, refer to
individual specifications.
Ensure to follow all instructions given in this manual on piping
installation, electric wiring, maintenance and inspection of actuated
valves, to eliminate concerns of accidental mishaps and product failures.
Mounting actuated metal valves on plastic piping may cause an excessive
load during manual operation, and damage the piping. Care must be
taken to eliminate such a concern

1-5-3. Actuator Operation Principle of ESR
● Opening operation (fully closed → fully open)
① If you turn on the motor power supply, the motor rotates and the motor force
is transmitted to the output shaft via the reduction gear and the valve rotates
in the opening direction.
② It opens the valve while lifting the spring attached to the output shaft.
③ When the Actuator shaft opens in the direction by 90°, it gets into contact
with the stopper inside the actuator and stops at the full-open position. At
this point, the motor stops and maintains the springs reaction force.
Fig.4
● Closing operation (fully open → fully closed)
① If you turn off the motor power supply the output shaft rotates to the closing
direction by the reaction force of the spring.
② When the Actuator shaft rotates to the closing direction by 90°, it comes
into contact with the stopper inside the actuator and stops at the fully closed
position.

2. Handling and Storage
2-1. Cautions for Handling and Storage
Handle actuated valves by holding valve bodies. Holding instrumentation cables
will cause electric wiring failures and other troubles (Fig.6).
Do not fall the product on the ground.
Protect the product from excessive impact
shock or vibration to eliminate concerns of
malfunction (Fig.7).
Overloading the product must be
prevented. Do not place any heavy object
on the product. Do not step on the product.
Do not store the product in the place subject to rain or high humidity. Poor
storage environment will cause product malfunction, such as corrosion inside the
product.
Do not disassemble the product to avoid malfunction or damage of the product.
The product is carefully packed to protect actuators and valves from intrusion of
dusts and other foreign objects. Do not unpack the product until you are ready
for installation on piping.
