Instructions for the installation of a Change-over Valve
EN
Support options with inlet and outlet side combination
1 Support of safety valves through bores in cast support brackets
2 Support of outlet pipeline
3 Support of Change-over Valves around flange circumference at safety valve side
4 Support of inlet pipeline
Ensure that the inlets and outlets of the Change-over Valve are sufficiently
large, suitable for the site and operating conditions and positioned to maximise
flow (see operating instructions for LESER safety valves).
Make sure that the medium can flow freely through the valve, so that the func-
tion of the safety valves is not impaired in any way.
The specified maximum pressures and inlet pressure losses for the built-in
safety valves, and the maximum operating temperature must not be exceeded.
