Range of Application
Safety valve
types 810/410, 811/411 and 812/412 for air, non-toxic gasand
technical steam
for protection against excess pressure inpressure tanks which are in
compliance with the specifications of the AD-2000 data sheet A2, or as equipment
component with safety function for pressure equipment in compliance with the EC
pressure equipment directive.
Safety valve
type 813/413 for fixed tanks for granular or powdered materials or
vehicle tanks for liquid, granular or powered materials
according to AD 2000 data
sheet HP 801 No. 23 which are discharged using compressed air. For protection
against excess pressure in pressure tanks which comply with the specifications of AD-
2000 data sheet A2, or as equipment component with safety function for pressure
equipment in compliance with the EC pressure equipment directive.
For details on the range of application of the individual versions please refer to the
technical documentation (catalogue) of the manufacturer.

General Notes
Safety valves are high-quality fittings which require a particularly careful handling.
The sealing surfaces are precision-machined at the seat and cone to attain the requi-
red tightness. Always avoid the penetration of foreign particles into the valve during
assembly and during the operation. The tightness of a safety valve can be impaired
when using hemp, Teflon tape, as well as through welding beads, among other things.
Also rough handling of the finished valve during storage, transport and assembly can
result in a safety valve leaking. If the safety valves are painted, make sure that the sli-
ding parts do not come into contact with the paint.

Installation and Assembly
Spring-loaded safety valves are to be installed with the spring bonnet pointing vertically
upward. The safety function of the valves is also guaranteed and tested in a horizontal
position. To ensure a satisfactory operation of the safety valves they must be installed in
such a way that the safety valve is not exposed to any impermissible static, dynamic or
thermal loads. Appropriate protection devices must be applied if the medium that dis-
charges upon actuation of the valve can lead to direct or indirect hazards to people
or the environment. Always pay attention to possible fumes discharging from the relief
bores in the spring bonnet. For example by fitting a blow-off/protective cover.
Supply
Supply connection pieces for safety valves are to be kept as short as possible and
are to be designed in such a way that there can be no pressure loss greater than
max. 3 % of the response pressure.
