4.0 Description
4.1 Scope of applications
Safety valves are used to protect pressurised systems.
The information complies to the Pressure Equipment Directive 97/23/EC.
It is the responsibility of the machine planner to ensure compliance.
The special markings on the valve must be taken into account.
Refer to the catalogue sheet to see which materials are used in standard versions.
Please contact the supplier or the manufacturer if you have any questions.
4.2 Operating principles
Safety valves are safety devices designed to prevent the pressure in any pressurised
system from exceeding the maximum permissible pressure by more than the permissible
tolerance of, usually +10%.
ATTENTION !
- Protect against external force (like impact, vibration, etc.).
- Valve mountings such as actuators, handwheels, hoods must not be used to
take external forces, e.g. they are not designed for use as climbing aids, or as
connecting points for lifting gear.
- Suitable materials handling and lifting equipment should be used.
See catalog sheet for weights.
ATTENTION !
- Refer to the data sheet for applications, limits on use and possibilities.
- Certain media require or preclude the use of special materials.
- The valves are designed for standard operating conditions. If conditions exceed
these requirements, e.g. aggressive or abrasive media, the operator should
state the higher requirements when ordering
- When media in Fluid Group 1 are used, seal exteriors must be designed so that
they pose no danger to humans or the environment.
- Open safety valves (open bonnet / open cap) are not permissible for fluids,
dusty atmospheres, open air use or for any Group 1 fluids in accordance with
Pressure Equipment Directive 97/23/EC.
