List of products by brand Asco

Brand background and product focus

ASCO is part of a long tradition in fluid automation and valve technology, with roots that include well‑known brands such as Sirai, which specialized in solenoid valves before being acquired into the ASCO portfolio. This history means the range combines decades of expertise in solenoid and pneumatic control with modern design and production.

The ASCO product lineup includes thousands of variations of solenoid valves — from compact general service valves to high‑flow and multi‑way control valves — used for fluids such as air, water, inert gases, steam, oil and other media in industrial and machine automation environments.

Typical applications and where the parts are used

ASCO solenoid valves and fluid automation products are found in:

• industrial automation and manufacturing flow systems

• commercial and process equipment requiring precise fluid control

• air and gas control circuits

• water, steam and heating systems
  These solutions also support automation tasks such as pilot valve control, multi‑way switching, and high‑flow shut‑off — useful in both OEM equipment and service/repair scenarios where reliable valve operation is critical.

Why ASCO parts matter

Using compatible ASCO parts helps maintain:

• precise fluid control and repeatable switching action

• stable flow regulation under varied operating conditions

• minimal downtime through engineered part reliability

• broad application support with many series and configurations

This makes ASCO solenoid valves and components essential in professional fluid control systems, from manufacturing lines and HVAC systems to machine water or steam control loops.
