Piping

Warning

1. Piping load and moment

Avoid any torsional or bending moments other than those

caused by the equipment’s own weight as failure to do so may

result in damage.

Support external piping separately.

If moment application is unavoidable during operation, the

moment should be lower than the max. moment shown below.

Piping materials without flexibility, such as steel tube piping,

are prone to being affected by excess moment loads or

vibrations from the piping side. Use flexible tubing in between

to avoid such effects.

Max. moment (M) = Length (L) x Load (F)

Length (L)

2. Before piping is connected, the pipes should be

thoroughly blown through with air (flushing) or

washed to remove chips, cutting oil and other

debris from inside.

Should they remain, they could cause a malfunction.

3. When connecting pipes and ﬁttings, etc., be sure

that neither chips from the pipe threads nor sealing

material get inside the valve.

When using sealant tape, leave 1.5 to 2 thread ridges

exposed at the end of the pipe/ﬁtting.

4. Connect piping/fittings using the recommended

torque while holding the female thread side tightly.

Insufficient tightening torque can result in loose piping or

sealing failure. Over tightening may break the thread. If the

female side is not held while tightening, excessive force will be

applied to the bracket directly, resulting in breakage.

Precautions on Design

Warning

1. Do not supply air pressure from ports other than

the 1 (P) port.

The valve will malfunction when air pressure is supplied from

other ports.

2. We recommend using a lock with a shackle

diameter of ø5 or more. If a lock with a shackle

diameter of less than ø5 is to be used, please test it

on the actual machine.

Installation and Adjustment

Caution

1. The valve must be switched to each position

instantly and securely. Stopping the handle

between the extreme positions may cause a

malfunction.

2. Double action type requires two actions (push the

handle and turn it). Confirm that the handle is

pushed properly before turning it. If the handle is

not pushed properly to the end, the internal parts

will be broken by turning the handle.

3. Tighten the 2 holding screws on the spacer with

bracket or spacer evenly.

Tighten them to the recommended tightening torque.

Insufficient tightening torque may result in loosening or sealing

failure. Excessive tightening torque may damage the thread,

etc.
