What Is the Shako BM520-02-S Solenoid Valve DC24V?

The Shako BM520-02-S is an electrically operated solenoid valve with a 24V DC coil, designed to control the flow of compressed air or compatible gases in pneumatic automation systems. It functions as a two-position directional control valve: when the coil is energized, the internal spool or poppet shifts to direct airflow from the supply port to the working port; when de-energized, a spring returns the valve to its rest position. This valve is widely used in factory automation for controlling pneumatic cylinders, air-powered grippers, blow-off nozzles, and vacuum generators where clean, fast, and repeatable air control is required.

In short: If your pneumatic system needs a reliable 24V DC solenoid valve to control airflow to an actuator or tool, the Shako BM520-02-S is an excellent choice, in stock at koeed.com.

Key Features

1. 24V DC Coil - Safe and PLC-Compatible

What it means: The solenoid operates on 24V DC, the standard control voltage in industrial automation panels worldwide.
Why it matters: 24V DC can be switched directly by PLC transistor outputs, relay outputs, or simple push-button circuits without additional interposing relays. It is also inherently safer than 110V or 220V AC coils in wet or accessible locations.
Result: Simple integration with any automation controller and reduced electrical safety concerns compared to line-voltage coils.

2. Fast Response for High-Cycle Applications

What it means: The Shako BM520 series is engineered for millions of cycles with consistent shift times, making it suitable for indexing and sorting applications where the valve cycles multiple times per second.
Why it matters: Sluggish valve response causes timing drift in high-speed automation, leading to misaligned product placement, missed actuations, and jammed conveyors.
Result: Precise, repeatable pneumatic control even in demanding high-cycle production environments.

3. Compact Body with Standard Port Threads

What it means: The BM520-02-S has a compact footprint with industry-standard port sizes (confirm thread type from label: typically Rc or NPT), allowing direct mounting on manifolds, sub-bases, or individual mounting brackets.
Why it matters: Standard port threads mean you can use off-the-shelf pneumatic fittings and tubing without special adapters, and the compact size fits in crowded machine enclosures where larger ISO valves would not.
Result: Quick installation, easy replacement, and compatibility with common pneumatic fittings from any brand.

Frequently Asked Questions

How do I confirm this valve is compatible with my existing pneumatic circuit?

Check four things on your existing valve: (1) the coil voltage - must be 24V DC, (2) the port configuration - how many ports and what is the flow path symbol on the valve body, (3) the port thread size - the 02 in BM520-02-S typically indicates 1/4 inch ports, and (4) the operating pressure range. If your old valve is also a Shako BM520-02-S, it is a direct replacement. Send us photos of your existing valve showing its markings and we will confirm compatibility.

The valve coil gets warm during operation - is this normal?

Yes. DC solenoid coils naturally generate heat during continuous energization - it is a normal characteristic, not a defect. The coil temperature will stabilize at a level that is warm to the touch but should not be too hot to hold. If the coil becomes extremely hot, scorching, or emitting a burning smell, check: (1) the supply voltage is actually 24V DC and not higher, (2) the valve spool is not mechanically stuck (a stuck spool prevents the armature from fully seating, increasing coil current), and (3) the ambient temperature around the valve is within the rated range.

Can I use this valve with lubricated compressed air?

The BM520 series is typically designed for use with clean, dry, filtered compressed air. If your system uses an air line lubricator (oil mist), check the valve's material compatibility - some internal seals and poppets are compatible with oil mist, while others may swell or degrade. As a general practice, if your system has been running lubricated air, continue with lubricated air; if it has been running dry, do not introduce oil. Switching between lubricated and non-lubricated air on the same valve can cause reliability issues.

What causes a solenoid valve to buzz or chatter?

Buzzing or chattering in a DC solenoid valve is often caused by: (1) insufficient voltage at the coil - check for voltage drop in long cable runs or corroded connectors, (2) contamination inside the valve preventing the armature from fully seating, (3) a damaged return spring that no longer holds the spool in its de-energized position, or (4) operating the valve outside its rated pressure range where differential pressure forces fight the solenoid. Clean or replace the valve if debris contamination is the cause; check the electrical supply if voltage is low.

Do you stock matching connectors and manifolds for this valve?

Contact our team with your requirements - we can supply compatible DIN connectors with LED indicators, sub-base manifolds for mounting multiple valves, and pneumatic fittings that match the BM520 port threads. Browse our pneumatic and fluid control components for related products.
