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
- إي إم سي: EV520S-02 (highly compatible mounting & port dimensions for PHS520S-02)
ملحوظة: 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.
عملية & إرشادات الصيانة
- يجب تصفية إمدادات الهواء; 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.
- التجاوز اليدوي: Standard non-locking: press to test, auto-reset upon release. L-suffix lockable version: rotate to lock spool position.
- استكشاف الأخطاء وإصلاحها: No LED light → check power supply; No shift when energized → verify supply pressure ≥0.15 MPa, inspect pilot orifice for debris blockage.

④ Port Specification (suffix after hyphen)
| لاحقة | Port Description |
| -02 | Inline threaded, Rc(حزب العمال)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%.

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.
- مستخدم / 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 أوه. Do not judge AC coil health by multimeter resistance; test by applying rated voltage.
Continuous exhaust port leakage indicates worn internal seals.
