Air Sequence Valve
Mode lB WD

Activates multiple air actuators in sequence.

PAT.

Delay time：1 ~ 10 sec
Suitable for environment where the electric use is not allowed or when the number of ports is limited.

Best Suited for Machining Centers
It controls the air flow by using a check valve, flow control valve, air tank, switching valve and activates multiple actuators in sequence.
This has a compact and high performance sealing structure and can be built into fixtures for machining centers.

Adjust Screw for Delay Time

Lock Nut

Delay Time : 1~10 sec.

Electric control is not required.

Circuit Symbol(T)

It can be installed in places where there is limited use ofelectricity such as explosion proof surroundings because
electricity control is not required.

Air pilot port is not required.

Incoming SideP (R) Port

Outgoing SideA Port

The actuators can be actuated with no air pilot port andminimum number of ports.

Weight0.2Notes :※1. Depending on the down time, the time delay of initial action may be longer.
※2. The time delay can be extended by adding a tank to T port and increasing its capacity.
※3. If actuators on the outgoing side do not operate after the time delayed setting, verify setting after pressure returns to zero.
※4. The confirmation for delayed time should be done after fastening the lock nut of the delayed time adjusting screw.
1. Depending on the circuit condition, the pressure of incoming side might decrease during operation of outgoing actuators
after directional control valve is switched.
2. Prepare time gap of more than 5 seconds until air is supplied again after air supply stops (releases).
3. Recommend the series connection if multiple valves are used in one circuit.

② Before the product is removed, make sure that the above-mentioned
safety devices are in place. Shut oﬀ the pressure and power source,
and make sure no pressure exists in the air and hydraulic circuits.

2) Regularly clean the area around the piston rod and plunger.
● If it is used when the surface is contaminated with dirt, it may leadto packing seal damage, malfunctioning and ﬂuid leakage.

③ After stopping the product, do not remove until the temperaturedrops.
④ Make sure there is no abnormality in the bolts and respective parts
before restarting the machine or equipment.
3) Do not touch a clamp (cylinder) while it is working.
Otherwise, your hands may be injured due to clinching.

3) Please clean out the reference surfaces on a regular basis (taper
reference surface and seating surface) of the locating products.

chips, adhesive coolant and others may not be removed. Make surethere are no contaminants before installing a workpiece/pallet.
● Continuous use with contaminant on components will lead tolocating accuracy failure, malfunction and ﬂuid leakage.

4) If disconnecting by couplers, air bleeding should be carried out
on a regular basis to avoid air mixed in the circuit.
5) Regularly tighten nut, bolt, pin, cylinder, pipe line and others toensure proper use.
6) Make sure the hydraulic ﬂuid has not deteriorated.
7) Make sure there is a smooth action without an irregular noise.
● Especially when it is restarted after left unused for a long period,
make sure it can be operated correctly.
8) The products should be stored in the cool and dark place
without direct sunshine or moisture.
9) Please contact us for overhaul and repair.
