Backfl ow Function
• With the backflow function it incorporates a mechanism to exhaust the air pressure in
the outlet side reliably and quickly.
Example 2)
When the air supply is cut off and
releasing the inlet pressure to the
atmosphere, the residual pressure
release of the outlet side can be
ensured for a safety purpose.
Example 1)
When the pressure in the rear and
the front of the cylinder differs:
