Coil Compatibility

Valve body PHS520S-02 is supplied without coil. Order separate Parker PEC5-XXV-D / DL coils:

PEC5-24V-D: DC24V, DIN connector, no LED

PEC5-24V-DL: DC24V, DIN connector with LED indicator

PEC5-220V-DL: AC220V, DIN connector with LED

Domestic Equivalent Selection Reference

Match thread size, flow rate and outer mounting dimensions as much as possible

Airtac: 4V210-08 (PT1/4, 5/2 single-solenoid, comparable flow)
JELPC: 4V210-08
EMC: EV520S-02 (highly compatible mounting & port dimensions for PHS520S-02)

Note: 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.

Operation & Maintenance Guidelines

Air supply must be filtered; 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.
Manual override: Standard non-locking: press to test, auto-reset upon release. L-suffix lockable version: rotate to lock spool position.
Troubleshooting: No LED light → check power supply; No shift when energized → verify supply pressure ≥0.15 MPa, inspect pilot orifice for debris blockage.

PHS520【Function Code】【Pilot Option】-【Port Code】-【Voltage】-【Wiring】-【Manual Override】

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

Code	Function Description
S	5/2‑way, Single‑solenoid spring return (PHS520S‑02 is this variant)
D	5/2‑way, 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 (Optional Suffix)

No marking: Internal pilot (standard for most models)

X: External pilot, requires separate external pilot air supply, for vacuum / low-pressure applications, e.g. PHS520SX-8

④ Port Specification (suffix after hyphen)

Suffix	Port Description
‑02	Inline threaded, Rc(PT)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.

Spool, 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 (most common)

110V: AC110V

220V: AC220V

⑥ Wiring Code

Code	Wiring Form
No marking	Direct wire‑out flying leads
FL	Direct wire‑out + LED indicator
D	DIN43650 connector, no LED
DL	DIN connector, with LED indicator + surge suppression, preferred for industrial field installation

⑦ Manual Override (Optional trailing suffix-L)

Code	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 & testing

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

Coils 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-station), M3 (3-station) … 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.
Used / 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 Ω. Do not judge AC coil health by multimeter resistance; test by applying rated voltage.

Continuous exhaust port leakage indicates worn internal seals.
