NOTE:
Avoid removing the actuator from the valve. The actuator has been calibrated at the
factory to ensure that the valve is tight. If the actuator is removed, it may have to be re-
calibrated.
Vexve Oy accepts responsibility only for actuators installed by Vexve.
Refer to the Hydrox product catalogue or data sheets (www.vexve.com) for maximum
permissible diameter of shaft and shaft intrusion. Actuator is equipped with only one key
way so it is not possible to change its installation position on the valve
WARNING:
All couplings and hoses of the actuator, and equipment connected to it, must always be
kept clean since impurities might cause failures in the operation of the system.
If the actuator is equipped with quick couplings and fast and significant changes in
temperature are possible, thermal expansion of the hydraulic oil must be taken into
consideration.
The actuator may not be removed or dismantled if the valve is pressurized! It is
recommended to use the special actuator removal tools!
Incorrect disconnection may cause serious personal injuries as well as malfunction and
damage to the equipment. Extreme caution must be exercised during the disconnection!
Do not use too high torques to operate the valve. Too high torques can damage the valve
or the actuator! See tables 1 and 2 in chapter 6.2.1 for maximum torques.
