Types of ASCO Solenoid Valves & How to Choose in Malaysia
If you’re working with fluid automation systems in Malaysia — be it in oil & gas, water treatment, manufacturing, or chemical processing, you’ve likely come across ASCO solenoid valves. Known for their reliability and performance, ASCO valves are widely used across industrial applications.
But with so many valve types available, how do you choose the right one?
In this guide, we’ll walk you through the main types of ASCO solenoid valves, their functions, and what to consider when selecting the best fit for your operation.
What is a Solenoid Valve?
A solenoid valve is an electromechanical valve used to control the flow of liquids or gases. It uses an electric current to activate a magnetic coil (solenoid) which opens or closes the valve.
ASCO, a trusted brand under Emerson, is one of the global leaders in solenoid valve technology, and Targetec Engineering is a reliable ASCO distributor in Malaysia offering a wide range of options for industrial needs.
Common Types of ASCO Solenoid Valves
1. Direct-Acting Solenoid Valves
How it works: The solenoid directly opens or closes the valve seat.
Best for: Low flow rate or low-pressure applications.
Industries: Water filtration, food & beverage, medical devices.
Example:
- ASCO 210 Series
- ASCO 238 Series Solenoid Valves
- ASCO Micro-Miniature Solenoid Valves – Designed for compact, high-precision applications like medical equipment or lab automation.
2. Pilot-Operated Solenoid Valves
How it works: Uses line pressure and an internal pilot to control the main valve operation.
Best for: Higher flow and pressure systems.
Industries: Oil & gas, chemical plants, manufacturing automation.
Example: ASCO 8210 Series
3. Two-Way Solenoid Valves
Flow paths: One inlet and one outlet.
Function: Typically used for on/off control of flow.
Application: Water control, fuel shut-off, general-purpose media.
4. Three-Way Solenoid Valves
Flow paths: One inlet and two outlets (or vice versa).
Function: Divert flow or alternate between two circuits.
Common use: Pneumatic systems, actuator control.
5. Explosion-Proof Solenoid Valves
Designed for: Hazardous environments with flammable gases or dust.
Certifications: Often ATEX or IECEx rated.
Application: Oil rigs, chemical facilities, offshore operations.
Example:
- ASCO 327 Series Solenoid Valves – Explosion-proof and suitable for harsh, hazardous areas.
6. Dust Collector Solenoid Valves
Use case: Controls pulse-jet cleaning in baghouse dust collection systems.
Benefit: Enhances air filtration system efficiency by controlling dust release pulses.
Example:
- ASCO 353 Series Solenoid Valves – High-flow pulse valves designed for dust collectors.
How to Choose the Right ASCO Solenoid Valve in Malaysia
When selecting a solenoid valve, consider the following factors:
- Media Type
Is the fluid air, water, oil, steam, or gas? Certain ASCO valves are designed for aggressive chemicals or high-temperature steam. - Operating Pressure and Flow Rate
Ensure the valve you choose supports your system’s pressure range and flow requirements. Pilot-operated valves are better for high-pressure applications. - Voltage and Power Requirements
ASCO solenoid valves come in various voltage options: 12V, 24V, 110V, 220V AC/DC. Match it with your electrical system. - Environmental Conditions
If you’re operating in a hazardous area, choose an explosion-proof ASCO valve. For cleanrooms or pharmaceutical environments, opt for stainless-steel or corrosion-resistant materials. - Certifications & Standards
Industries like food & beverage or medical devices may require FDA, CE, or ATEX certifications. ASCO valves offer a range of compliant products.

Common FAQ About ASCO in Malaysia
What are ASCO solenoid valves used for?
ASCO solenoid valves control the flow of liquids and gases in systems across oil & gas, water treatment, chemical plants, and manufacturing automation.
What is the difference between direct-acting and pilot-operated solenoid valves?
Direct-acting valves operate using only the solenoid coil and are suitable for low-pressure systems. Pilot-operated valves use system pressure to assist operation, ideal for higher flow and pressure conditions.
Are ASCO valves safe for hazardous environments?
Yes, ASCO offers explosion-proof solenoid valves like the ASCO 327 Series, certified for use in hazardous locations (ATEX, IECEx).
How do I choose the right ASCO valve in Malaysia?
Consider your media type, system pressure, voltage, environmental condition, and certifications required. For expert advice, contact us.
How do I choose the right ASCO valve in Malaysia?
You can buy original ASCO solenoid valves from Targetec Engineering, an authorized distributor in Malaysia with product support and fast delivery.
Do ASCO valves come in different voltages?
Yes. ASCO solenoid valves are available in 12V, 24V, 110V, and 220V (AC/DC) to match various system needs.
