1. Introduction to ASCO Solenoid Valves

ASCO solenoid valves are a world-renowned brand in the field of flow control equipment. With over 100 years of experience, ASCO (a member of Emerson – USA) specializes in manufacturing high-quality solenoid valves widely used in various industries such as oil & gas, chemicals, food & beverage, water treatment, HVAC, and environmental applications.

ASCO valves stand out for their durability, stable operation, and compliance with strict international safety and energy-saving standards.

2. Structure and Working Principle

• Structure: Includes valve body (steel, brass, stainless steel), solenoid coil, ferromagnetic plunger, and return spring.

• Working principle: When an electric current flows through the solenoid coil, the magnetic field pulls the plunger to open the valve, allowing liquid/gas to pass. When the power is off, the spring pushes the plunger back to its original position, closing the valve and stopping the flow.

3. Key Advantages of ASCO Solenoid Valves

• Compact design, easy installation.

• High durability and long service life.

• Fast response and precise flow control.

• Available in a wide range of materials (brass, stainless steel, engineered plastics).

• International certifications: ISO, CE, ATEX.

• Various models: normally closed (NC), normally open (NO), explosion-proof solenoid valves.

4. Applications of ASCO Solenoid Valves

ASCO valves are widely used in multiple industries:

• Pneumatic and hydraulic systems.
