Use an air filter on the IN side for operating protection.
If a stop valve or a silencer is connected to the exhaust port of VHS20/30,
the effective sectional area should be larger than the figure indicated in the
following table, to prevent malfunction caused by back pressure. (This is
not applicable to VHS40)
If unit is to be used in a washdown application, avoid directing fluid
into the exhaust port.
With the use of a 3 port valve for residual pressure release, pressure left in the
line can be easily exhausted.
