Caution
1. Before starting the disassembly work, be sure
to shut off the power supply and pressure
supply, and then release the residual pressure.
Disassembly
1) Loosen the hexagon bolts and remove the bonnet,
O-ring, and main valve (sub-valve).
Assembly
1) Assemble the main valve (sub-valve) to the body. The
main valve (sub-valve) has a required mounting direction.
Assemble the valve referring to Fig. 1.
If the valve is assembled in incorrect direction, it can cause a malfunction.
2) Mount the O-ring to the body groove. (See Fig. 2.)
After mounting of the O-ring, check if the O-ring is
fitted properly in the groove. If it is out of the groove,
external leakage and/or operation failure may occur.
3) Assemble the bonnet to the body.
4) Tighten the hexagon bolts diagonally.
(See Table 1 for the tightening torque.)
