Especificações Técnicas Principais

Recursos do produto

1. Internal pilot design, baixo consumo de energia da bobina, 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, baixo custo de manutenção
4. Independent exhaust ports, silencers can be fitted for noise reduction
5. Certificado CE, 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: CC24V, DIN connector, sem LED

PEC5-24V-DL: CC24V, 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. ártico: 4V210-08 (PT1/4, 5/2 solenoide único, comparable flow)
2. JELPC: 4V210-08
3. EMC: EV520S-02 (highly compatible mounting & port dimensions for PHS520S-02)

Observação: 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.

Operação & Diretrizes de Manutenção

1. Air supply must be filtered; 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. Manual override: Standard non-locking: press to test, auto-reset upon release. L-suffix lockable version: rotate to lock spool position.
5. Solução de problemas: 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 (Sufixo Opcional)

No marking: Internal pilot (standard for most models)

X: External pilot, requires separate external pilot air supply, for vacuum / low-pressure applications, por exemplo. 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.

Carretel, 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: CC24V (mais comum)

Separate-order Coil Models (PEC5 Series)

Corpo da válvula fornecido sem bobina; coils must be ordered separately:

PEC5-24V-D: DC24V DIN connector, sem LED

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

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

Bobinas 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-estação), M3 (3-estação) … 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. Usado / 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

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