CAUSE REACTION FORCE TO EXTERNAL STRESS
EFFECT Deformation, structural failure
DANGER
Breakage or deformation of the body, leaking fluid
SOLUTION 1. Check there are not external loads, it is compulsory for the installation technician to
protect the valve from external stress.
2. This manual, in section 2 point 2.1 describes the indications in point 1 and 2.
3. The installation technician must check the valve is free of hazards due to external reaction
forces and/or stress.
CAUSE WORKING TEMPERATURES
EFFECT
Metal parts at high temperature
DANGER Burns
SOLUTION 1. Install the valve in a protected area or insulate the valve.
2. The user must signal the hazard using suitable signs indicating the parts can reach high
and dangerous temperatures. It is indicated in section 1 of the manual. “General safety
information”
3. Wear adequate personal protection
CAUSE
VALVES WITH ELECTRICAL ACTUATOR – VOLTAGE!
EFFECT Electric shock with subsequent consequences based on exposure
DANGER Danger for the safety of those carrying out works or for third parties.
SOLUTION
4. The actuator to standard is protected by a cover IP65, do not remove it without sectioning
or isolating the power supply voltage.
5. A switch must be planned and signalled by a specific sectioning/insulation label on the
actuator.
The system must correspond to standards DIN IEC 60364-4-41, responsible
protection class I, protection class III(24V AC / 24V DC) and also the standard DIN IEC
60364-4-44 in compliance with the overvoltage categories of the actuator.
6. Electrical actuators have no switch, comply with the information in this manual.
CAUSE INSTALLATION AND/OR USE NON-COMPLIANT WITH THE PROVISIONS, THE
DIRECTIVES IN FORCE AND NATIONAL LEGISLATION
EFFECT Inappropriate installation, breakage of the valve
DANGER Poor system operation, leaking fluids
SOLUTION
1. The installation technician and/or user must install the valve in compliance with the
Directives in force and national legislation
2. Not applied
3. In this manual, it is described in point 1. “General safety information”
CAUSE
VALVE MAINTENANCE WITH SYSTEM PRESSURISED
EFFECT
Incorrect maintenance
DANGER Poor operation of the system, danger of projection of pressurised parts, danger of leaking
fluids
SOLUTION
1. Maintenance activities must be carried out with the valve shut off.
2. The valve must be free of hydrostatic pressure.
3. The valve must be shut off as described in this manual in point 1. “General safety
information”
