tachment screws.
DZ13/14 The shutoff and equalization valves DZ13/14 in three and four spindle versions are highly
suitable when mounting differential pressure devices. The following can be used for ex-
ample:
•
is a system is to be depressurized or taken out of operation
•
for repairs or tests to disconnect differential pressure devices within the affected
systems from the mains supply
The shutoff devices can therefore also be used for function tests on site. In contrast to
DZ13, the DZ14 also has a venting valve to vent the conected pipe system. The shutoff
and venting valves are designed for the rated pressure level PN40. The housing can be
selected in aluminium, brass or chrome-nickel-steel 1.4301. There are various pressure
connections (see order code) available for process-side screw connections.
