Domestic Equivalent Selection Reference
Match thread size, flow rate and outer mounting dimensions as much as possible
- artico: 4V210-08 (PT1/4, 5/2 single-solenoid, comparable flow)
- JELPC: 4V210-08
- EMC: EV520S-02 (highly compatible mounting & port dimensions for PHS520S-02)
Nota: PHS520S-02 is pilot-operated; 4V210-08 is direct-pilot type. Differences exist in power consumption and internal construction. Prior to drop-in replacement, verify cylinder actuation speed and minimum working pressure.
Operazione & Linee guida per la manutenzione
- L'alimentazione dell'aria deve essere filtrata; recommend 40 μm filter-regulator unit. Prevent liquid water/oil from entering valve cavity.
- Never energize bare coil; coil must be assembled onto valve body.
- Preferred mounting orientation: coil upward or horizontal.
- Azionamento manuale: Standard non-locking: press to test, auto-reset upon release. L-suffix lockable version: rotate to lock spool position.
- Risoluzione dei problemi: No LED light → check power supply; No shift when energized → verify supply pressure ≥0.15 MPa, inspect pilot orifice for debris blockage.

Example complete model: PHS520S-02-24V-DL-L
① Series: PHS520
5-port internal pilot pneumatic solenoid valve, rubber seal, Parker Korea origin
② Valve Body Function Code
| Codice | Descrizione della funzione |
| S | 5/2-modo, Single‑solenoid spring return (PHS520S‑02 is this variant) |
| D | 5/2-modo, Double‑solenoid latching, pulse trigger, no spring return |
| C | 5/3‑way Center Closed (A/B ports blocked in center position) |
| E | 5/3‑way Center Exhaust (A/B ports exhausted in center position) |
| P | 5/3‑way Center Pressure (A/B ports pressurized in center position) |
③ Pilot Option (Suffisso opzionale)
No marking: Pilota interno (standard for most models)
X: External pilot, requires separate external pilot air supply, for vacuum / low-pressure applications, per esempio. PHS520SX-8
④ Port Specification (suffix after hyphen)
| Suffisso | Port Description |
| ‑02 | Inline threaded, Rc(P.T)1/4; Exhaust Rc1/8; standalone threaded valve body |
| ‑8 | Manifold base mounting, no external threads; mounts onto PHS520‑M multi‑station manifold, internal manifold air channels |
⚠️ PHS520S-02 VS PHS520S-8 Key Comparison
- PHS520S-02: Inline threaded valve: Valve body has threaded ports for direct pipe connection, standalone operation without manifold.
- PHS520S-8: Manifold-mount valve: No external pipe threads, must install on PHS520-M-series manifold base. Designed for multi-valve banks, cannot accept direct pipe fittings.
Bobina, flow rating, pressure rating and coils are fully interchangeable between the two variants; PEC5-XXV-D/DL coils cross-fit 100%.
⑤ Coil Voltage
24V: DC24V (più comune)
110V: AC110V
220V: AC220V
⑥ Wiring Code
| Codice | Wiring Form |
| No marking | Direct wire‑out flying leads |
| Florida | Direct wire‑out + Indicatore LED |
| D | DIN43650 connector, no LED |
| DL | DIN connector, con indicatore LED + soppressione dei picchi, preferred for industrial field installation |
⑦ Manual Override (Optional trailing suffix-L)
| Codice | Manual Override Type |
| No marking | Non‑locking push‑to‑test: press for test, auto‑reset; cannot hold spool position |
| l | Lockable lever override: rotate to mechanically lock spool position for maintenance & test |
Separate-order Coil Models (PEC5 Series)
Valve body supplied without coil; coils must be ordered separately:
PEC5-24V-D: DC24V DIN connector, no LED
PEC5-24V-DL: DC24V DIN connector with LED
PEC5-220V-DL: AC220V DIN connector with LED
Bobine 100% interchangeable between PHS520-02 and PHS520-8 bodies.
Manifold Bases (for-8 manifold-mount valves)
PHS520-M N, N = number of stations:
PHS520-M2 (2-stazione), M3 (3-stazione) … M15; Blank-off plate: PHS520-BP-1
Common Selection Pitfalls Summary
- Do not confuse-02 inline threaded and-8 manifold-mount versions; -8 bodies cannot accept direct pipe threads.
- Suffix-X = external pilot. Do not select-X for standard cylinder control; external pilot air supply is mandatory, otherwise valve will not shift.
- 5/3-way valves (C/E/P) minimum working pressure 0.2 MPa, higher than 5/2-way valves at 0.15 MPa.
- Usato / second-hand valve inspection checklist:
No body cracks; manual override pushes and returns smoothly.
Pneumatic test at 0.4-0.5 MPa supply pressure; verify home position with power off; confirm shift upon energization, spring return upon de-energization.
DC24V coil resistance approx. 950-1100 OH. Do not judge AC coil health by multimeter resistance; test by applying rated voltage.
Continuous exhaust port leakage indicates worn internal seals.
