Pressure surge test to DIN 1988, Part 2

In order to meet the pressure surge test requirements of DIN 1988 Part 2,
the exhaust air must be vented through a restrictor having a maximum diameter
of 1 mm.
The flow restriction options are as follows:
•
Integrated construction of a restrictor or a one-way flow restrictor directly
in the pneumatic actuator.
•
Restrictor in the exhaust air port of a 4-way pilot valve.
•
Restrictor or one-way flow restrictor directly at the outlet of a
3-way pilot valve.
Bürkert offers the appropriate valves for this purpose.
