Pressure Control Valve
¡Handling
zTo adjust pressure, loosen the lock
nut and then rotate the handle clockwise (rightward) to increase pressure
or counterclockwise (leftward) to
decrease it.
xMake sure that drain port back
pressure is no greater than 0.2MPa
{2.0kgf/cm2}.
cWhen configuring pipes for the
pressure control valve and remote
control valve, use of thick iron pipe
with an inside diameter of no more
than 4mm and a connection length
of no more than three meters is
recommended. Pipe capacity can
be a source of vibration.
vWhen an adjustment bolt type is
required for the pressure adjustment block, insert K for the type
specification. See the dimension
drawings, RC-G02 only.
bUse the following to specify a sub
plate.
Note) For mounting bolts, use 12T or equivalent.
