2. Individual pipe mounting: with separate base

Manifold MF520-02 supports 2~10 stations, with blanking plugs and mufflers optional

7. تثبيت, التكليف & Operation Rules

تثبيت

1. Install air filter (≥40μm) upstream; air treatment triple unit is recommended; no oil & dirt contamination allowed
2. No strict mounting orientation; keep coil facing upward to avoid water accumulation
3. Purge all piping before connecting the valve to prevent metal chips jamming the spool
4. Install mufflers on exhaust ports for noise reduction and dust prevention; never block exhaust ports

Manual Override Button

Press down: force spool to shift; rotate 90° to lock the shifted position for continuous testing

إعادة ضبط: turn back to unlock; spring resets automatically after release

Manual lock is only for commissioning; do not keep locked during normal operation

Power-on Commissioning Sequence

1. Supply compressed air up to rated pressure and check for air leakage
2. Apply DC24V power and verify cylinder movement; check LED lamp (L model)
3. Cut power to confirm automatic spring reset

Working Principle — SHAKO PU520-02S-DC24V

5/2 five-port two-position, الملف اللولبي واحد, internal pilot solenoid valve

المبدأ الأساسي: The coil only actuates a small pilot valve; air pressure difference from main supply pushes the main spool to shift; spring resets automatically when power cuts off (not direct pull by coil like direct-acting valves)

الهيكل الداخلي

1. Solenoid assembly (DC24V coil + حديد التسليح): controls the small pilot valve
2. Pilot air circuit: internal pilot, air is tapped from P inlet; no external control air required
3. Main spool & return spring
4. Five ports: ص (inlet), A/B (outlets), R/S (exhausts)

Key limitation: Internal pilot needs minimum inlet pressure ≥0.15 MPa (1.5 حاجِز) to build pressure difference for spool actuation; select PU520A external pilot for low-pressure & vacuum applications

1. De-energized State (Normal Position, Spring Return)

تم إلغاء تنشيط الملف, armature drops, pilot valve closes; pilot control chamber vents

Right-side return spring pushes main spool to left

Air circuit: P ↔ A open; B ↔ S exhaust

Cylinder A side air inlet, B side exhaust; cylinder stays at initial position

2. Energized State (DC24V Powered On)

يتم تنشيط الملف, magnetic force pulls armature up; pilot valve opens

Compressed air from P inlet flows through pilot hole into right-side control chamber

Pressure on right side overcomes spring force; air pressure pushes main spool to shift

Air circuit switches: P ↔ B open; A ↔ R exhaust

Cylinder B side air inlet, A side exhaust; cylinder reverses movement

3. Power Cut Off Again

Magnetic force disappears, pilot valve closes; air inside pilot chamber vents out from pilot exhaust hole

Main spool is pushed back to original position by return spring; air circuit reverts to P-A open status

✅ Feature of single solenoid (س): auto reset on power loss (monostable); select double solenoid (د) for position latching without power supply.

Manual Override Principle

The lockable manual push button mechanically actuates the pilot spool without power or air supply, simulating energized status for field commissioning. Rotate 90° to lock the shifted position; remember to unlock after testing.

Advantages over Direct-Acting Valves

Low coil power (≈4.8W), حجم صغير, low temperature rise

Large spool flow capacity (18 mm² effective area)

يدعم 100% continuous energization (100% الضعف الجنسي)

عيب: Minimum actuating pressure threshold; cannot work under zero pressure
