Installation and Assembly
Spring-loaded safety valves are to be installed with the spring bonnet pointing ver-
tically 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 impermissib-
le static, dynamic or thermal loads. During installation the max. torque value must
not be exceeded (see chart). Appropriate protection devices (for example by fitting
a blow-off/protective cover) must be applied if the medium that discharges upon
actuation of the valve can lead to direct or indirect hazards to people or the environ-
ment. Always pay attention to possible fumes discharging from the relief bores in
the spring bonnet.
Valve size
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.
