4V210-08 Solenoid Valve

Overview

The 4V210-08 solenoid valve is a compact pneumatic 5/2-way valve widely used in industrial automation to control the flow of compressed air to pneumatic actuators and cylinders. In the standard 4V200 series coding, the 4V210 designation identifies a five-port, two-position, single-solenoid valve, while the -08 suffix indicates 1/4 inch porting. This example is configured with a 120 V AC coil, as stated in the original listing.

Because the 4V210-08 is built to the widely used 4V200 footprint, it suits both new machines and replacement duty in plants where standard pneumatic solenoid valves are already installed. The valve supplied is new and, per the original listing, of Chinese origin.

Engineering & Design

When the solenoid coil is energised, the magnetic force shifts the internal spool, connecting the supply port to one working port while the opposite working port is vented to exhaust. When the coil is de-energised, the spool returns to its original position, reversing the connection. This two-position operation is the standard arrangement for single-solenoid 5/2-way valves and is what allows a simple electrical signal to drive the full stroke of a pneumatic cylinder.

The valve body and spool arrangement follow the common 4V200 series layout, which makes the 4V210-08 mechanically and pneumatically interchangeable with other valves built to the same standard pattern. Maintenance is limited to keeping the air supply clean and dry and verifying the coil voltage matches the plant supply.

Key Features

• 5/2-way single-solenoid pneumatic valve in the standard 4V200 series footprint, the arrangement used by the 4V210-08 solenoid valve
• -08 porting suffix: 1/4 inch ports in the 4V200 model coding
• 120 V AC solenoid coil as per the original listing
• New, unused condition
• Country of origin: China (per original listing)
• Direct electrical control of pneumatic actuators without pilot air plumbing

Applications

• Actuation of single-acting and double-acting pneumatic cylinders
• Air control on packaging, assembly and material-handling machinery
• General machine automation and pneumatic circuits
• Replacement duty for existing 4V210-08 solenoid valves in plant equipment

Specifications

Compatibility & Integration

The 4V210-08 solenoid valve is a drop-in style replacement for other valves built to the same 4V200 standard, which is one of the most common pneumatic valve families in industrial use. The 120 V AC coil means it connects directly to a standard AC control circuit without a separate DC power supply.

Before fitting, confirm the working pressure of the machine air supply is within the rating of the valve family and that the port threads match the existing manifold or tubing fittings. Our team can confirm fit details against the application before dispatch.

Every 4V210-08 solenoid valve we supply is checked against the model number and coil voltage before dispatch, and our team confirms the valve matches your application before you order.

FAQ

Checking Compatibility Before Replacement

Many valves share the 4V200 footprint, but coil voltage and port thread must match for a direct swap. Before fitting a replacement, check the markings on the old valve and on its coil:

• The model code, confirming a single-solenoid 5/2 valve (4V210) with 1/4 inch ports (-08).
• The coil voltage: this unit has a 120 V AC coil, so it is not a direct substitute for a valve with a 24 V DC or 220 V AC coil.
• The thread type in the ports and the fittings already installed.
• Whether the valve is mounted individually or on a manifold, and whether manual override access is needed.

Installation Tips

Blow out the supply line before connecting the valve to remove debris, and use thread sealant sparingly so it does not enter the valve. Connect the supply to port 1, the working lines to ports 2 and 4, and fit silencers to the exhaust ports. Check that the air supply is filtered and within the operating pressure range stated in the specifications, then energise the coil and confirm that the cylinder moves in the correct direction.

Troubleshooting Common Faults

If the 4V210-08 solenoid valve does not shift, check the coil voltage at the connector and listen for the coil energising; if it energises but the spool does not move, suspect low supply pressure or contamination. Air leaking from the exhausts while at rest usually indicates worn spool seals. Where the valve hums loudly on AC supply, check for dirt on the armature or a supply voltage outside tolerance.

Use in Oman and the GCC

Packaging lines, water treatment skids, workshop equipment and general machinery across the region use standard 4V series valves because spares are easy to replace. Seven Star LLC supplies this valve for maintenance and project needs and can help check coil voltage and port size against your existing equipment.
