Grundlegende technische Spezifikationen

Produktmerkmale

1. Internal pilot design, low coil power consumption, suitable for long-duration continuous energization, low risk of coil burnout
2. Direct inline threaded mounting; compatible with PHS520-series manifold bases for multi-valve assembly
3. PEC5-series coils can be individually removed and replaced, valve body reusable, geringe Wartungskosten
4. Independent exhaust ports, silencers can be fitted for noise reduction
5. CE-zertifiziert, widely used for cylinder directional control in packaging machinery, machine tools and automation production lines

Coil Compatibility

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

PEC5-24V-D: DC24V, DIN connector, keine 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

1. Arktis: 4V210-08 (PT1/4, 5/2 single-solenoid, comparable flow)
2. JELPC: 4V210-08
3. EMV: EV520S-02 (highly compatible mounting & port dimensions for PHS520S-02)

Notiz: 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.

Betrieb & Wartungsrichtlinien

1. Die Luftzufuhr muss gefiltert werden; recommend 40 μm filter-regulator unit. Prevent liquid water/oil from entering valve cavity.
2. Never energize bare coil; coil must be assembled onto valve body.
3. Preferred mounting orientation: coil upward or horizontal.
4. Manuelle Überbrückung: Standard non-locking: press to test, auto-reset upon release. L-suffix lockable version: rotate to lock spool position.
5. Fehlerbehebung: 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

③ Pilot Option (Optionales Suffix)

No marking: Interner Pilot (standard for most models)

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

④ Port Specification (suffix after hyphen)

⚠️ PHS520S-02 VS PHS520S-8 Key Comparison

1. PHS520S-02: Inline threaded valve: Valve body has threaded ports for direct pipe connection, standalone operation without manifold.
2. 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.

Spule, 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 (am häufigsten)

110V: AC110V

220V: AC220V

⑥ Wiring Code

⑦ Manual Override (Optional trailing suffix-L)

Separate-order Coil Models (PEC5 Series)

Valve body supplied without coil; coils must be ordered separately:

PEC5-24V-D: DC24V DIN connector, keine 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

1. Do not confuse-02 inline threaded and-8 manifold-mount versions; -8 bodies cannot accept direct pipe threads.
2. Suffix-X = external pilot. Do not select-X for standard cylinder control; external pilot air supply is mandatory, otherwise valve will not shift.
3. 5/3-way valves (C/E/P) minimum working pressure 0.2 MPa, higher than 5/2-way valves at 0.15 MPa.
4. Gebraucht / 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.

PHS520S-02 vs PHS520S-8 Main Difference

PHS520S-02: Inline threaded valve, integral PT threads for direct pipe connection

PHS520S-8: Manifold-base valve, no pipe threads; must mount onto PHS520-M manifold base

Spule, flow performance and coils are fully interchangeable; only mounting configuration differs.
