the flow passage from the outlet port A to the
exhaust port R to be released but at the same time
ensuring that the main valve is and remains closed
preventing any loss of air.
The pilot air of the piston is also exhausted from
the pilot valve and the piston is returned upwards
due to a spring.

open as a function of the inlet and outlet pressure.

Table 2: Thanks to its built-in silencer (optional),
space saving is achieved in the AV ] series.
The above table demonstrates the improved flow
rates. Since the flow characteristics from 1(P) to
2(A) has been improved, the rapid supply time has
been reduced by almost half (compared with the
old AV series).
Conclusion
The characteristics and features of the new AV-A
series are indicators of just how much research
has been put into this. From its size reduction
to power savings, each detail has been carefully
thought out to match not only the requirements of
those customers who submitted NPDPs but for all
customers who can now benefit.
Training has been conducted around the coun-
try and sales engineers have been receiving cus-
tomer feedback in the form of surveys to ensure
that the refreshed product meets and exceeds re-
quirements and expectations.
