* According to Pressure Equipment Directive for compressible fluids of
Group 1 (dangerous gases and vapours according to Art. 3, no. 1.3, letter
a, first dash)
The required minimum pilot pressure P min for control function B and I (flow
direction below seat) depends on the medium pressure.
The pressure graphs can be found in the operating instruc-
tions online at www.country.burkert.com
