Control section

The spool section is the base of the APV-16 control section, it contains the 2-way compensator with delta p

adjustment, so the flow can be adjusted without using the stroke limitation.

Each control section has measuring ports (Ya, Yb) on LSa and LSb, and LS adjustment per user port. To

change between the several control types, different endcaps are used.

6

Control spool

There are 2 basic control spools available, the A spool with all ports closed in neutral position and the C

spool with P closed and A en B to T in neutral position, with 20% of nominal opening to T.

Example circuit

The APV-16-A is meant for customers who design and produce the manifold or subplate themselves. In the

example diagram the circuit of a manifold with two control valves is shown.

The pilot line needs 28- to 35 Bar pressure or 406- to 508 PSI pressure, The L-connection is ideally

separately connected to tank.

LS connection of valve 1 connects to the LS cascade entering valve 2 through the Z connection.

The LS connection of valve 2 connects to the LS port of the pump, or to the Z connection of another valve

in the manifold system. Z connection of valve 1 needs to be connected to the T-line

If only 1 control valve is used, than the Z connection also has to be connected to the T-line.

System integration

Mounting procedure

- AMCA-valves shall not be mounted by overtightening of mounting bolts, causing mechanical distortion and

thus spool lock. (50 Nm)

- Mounting on flat surface, flatness □ 0,01/100 mm (0.0004/3.9 inch)

- Don’t use conical thread for port fittings.

- For sealing purposes use O-rings.

- Check the voltage and current of the solenoid before operation.

- Avoid ingression of contamination during mounting.

- Check if the hydraulic pipes, tank and the oil are clean and demands to the needed requirements (NAS 1638

class 8)

Fluid maintenance

Due to the construction, the APV-valve is not highly susceptible to particulate (silt type) lock, nor to

contaminant wear. Therefor the contaminant sensitivity is low.

- Use mineral oil. Other fluids on request.

- Keep the contamination level better or equal to NAS 1638 class 8 or ISO 4406: 18/16/13.

Startup procedure

- Check if all ports are connected according to the diagram before starting the pump or setting the valve

under pressure.

- To further bleeding, it is recommended to switch the valve under a low pressure. This will satisfy in most

cases.

- In most cases, the manufacturer has set, according to order the flow and pressure of the valve. When these

settings have to be changed please see page 18 to check the possibilities.

Troubleshooting

1) System pressure and pressure setting too low

a. 1 main load pressure relief (1) contaminated.

Cause: dirt particles between cone and seat.

Solution: turn adjustment counter clockwise, activate the directional valve several times. If

necessary dismantle the main load pressure relief (1). Check for damages, if so replace cone and

seat.

Examine the system filter.

b. Damping orifice (2) or (11) blocked (dirt or fouled) if necessary remove and clean

c. 3-Way compensator spool jammed open. When removing plug(4) the spring should pudh out the 3-

way compensator (3).

Examine the 3-way compensator and bore for dirt or damages. If necessary, deburr with care. Flush

the spool to remove dirt.

d. Fault in other components in the system.

Check for a damaged pump, motor, seals etc.

2) User moves erratically

a. Air in system

Bleed the end-and springcaps (7/8) or the hendle mechanism with the stroke limiting screws.

19

b. Solenoid faulty

Remove the solenoid (6) and check the pilot spool on dirt. If possible, swap solenoid to another

section to detect faulty unit.

c. Excessive friction of the main spool

Remove both end- and scpringcaps end remove the main spool. Examine the main spool and bore

for dirt or damages. If necessary, deburr with care. Examine system filter.

d. Excessive damping

See 2.b.

e. Excessive friction in other components in the system.

3) User doesn’t work or works too slow

a. Damping orifice (11) blocked (dirt or fouled).

b. Main load pressure to low.

c. Main spool doesn’t switch

See 2.C. or pressure reducing valve (10) is dirty, clean and remount.

d. There is insufficient user load.

4) Pump does not unload.

a. 3-Way compensator spool jammed. See 1.C.

b. Main spool doesn’t center. See 2.C. Electrical fault, check the electrical circuit.
