GE  1S420ESWBH3A – Compact 5‑Port Solenoid Valve for Fast, Reliable Manifold Pneumatic Control

The GE 1S420ESWBH3A sits in the popular 1S series of compact 5‑port solenoid valves, built for high‑cycle OEM machinery where space, response time, and serviceability matter. From my experience, the 1S “size‑2” footprint works well on multi‑station manifolds, keeping wiring and tubing neat while delivering consistent switching across millions of cycles. You might notice that options like LED/surge suppression and manifold bases simplify panel work and reduce downtime in many cases.

Our Order Process & Guarantees

• Delivery time: typically 1 week if in stock; no more than one month at the latest
• Payment: 50% advance payment; full payment prior to delivery
• Express delivery methods: FedEx, UPS, DHL

Key Features

• 5‑port, 2‑position architecture – A practical choice for double‑acting cylinders and pneumatic actuators, minimizing circuit complexity.
• Compact “1S” body – Typically slim and lightweight, ideal for dense manifolds or tight machine envelopes.
• LED and surge‑suppressed coil – Easier diagnostics on the line and better protection for PLC outputs and drivers.
• Manifold or single‑base mounting – Scales from one valve to multi‑station banks without redesigning your panel.
• Fast response – In many cases reduces cylinder cycle time and improves throughput on pick‑and‑place or indexing stations.
• Service‑friendly design – Coils and valve bodies are typically easy to swap, cutting mean time to repair.

Technical Specifications

Application Fields

This model is typically used in high‑cycle automation cells: packaging lines, pick‑and‑place gantries, PCB handling, machine tool auxiliary actuators, small automotive jigs, food & beverage end‑of‑line equipment, and compact assembly fixtures. One thing I appreciate is how easily it slots into manifold banks when you need to add two or three more cylinders late in a project.

Advantages & Value

• Reliability in continuous duty – Suited for 24/7 lines; reduces unplanned stops.
• Compatibility – Works with 1S series manifolds, bases, and standard pneumatic fittings, lowering integration effort.
• Lower total cost – Quick coil/valve replacement and simple wiring typically cut maintenance time.
• Support – We can assist with valve selection, coil voltage matching, and manifold sizing before you commit.

A packaging OEM told us they shaved a day off commissioning by using pre‑wired 1S manifold blocks with LED coils—fault finding was practically point‑and‑see.

Installation & Maintenance

• Environment – Mount in a clean, ventilated cabinet or protected area; avoid oil mist and dust ingress where possible.
• Pneumatic quality – Use filtered, dry air (e.g., 5 μm filtration). Drip‑leg and dryer recommended for consistent actuation.
• Wiring – Observe coil polarity for DC. LED/surge models help protect PLC transistor outputs.
• Exhaust & noise – Fit silencers/mufflers on exhaust ports to keep noise down and prevent debris ingress.
• Routine checks – Periodically inspect coils and connectors, clean or replace silencers, and cycle valves while monitoring for sluggish response.
• Spares – Keeping one spare coil and one valve body per manifold row typically prevents extended downtime.

Supporting Components

• 1S series manifold bases (multi‑station) with common supply/exhaust galleries
• Single sub‑bases for stand‑alone mounting
• LED/surge‑protected coil assemblies and pre‑wired cable sets
• Standard pneumatic fittings and silencers for body‑ported connections
• Inline flow controls for cylinder speed tuning

Quality & Certifications

• Manufactured under ISO 9001 quality systems (typical for this series)
• CE and RoHS conformity commonly available for coils and valve assemblies
• Manufacturer’s standard warranty: typically 12 months (varies by region)
• Our coverage: 365‑day warranty from delivery
