Asco HVAC Control Valves & Actuators

Asco HVAC Control Valves & Actuators: Precision Engineered for Demanding Systems

When it comes to managing the flow of air, steam, water, and other media through commercial and industrial HVAC systems, few names carry the weight of Asco. Since 1910, Asco Valve has been the primary choice of engineers, contractors, and OEMs worldwide, and that century-plus track record is especially meaningful in the exacting world of HVAC control.

Asco, a division of Emerson Electric Co., is a well-known manufacturer of fluid automation and control solutions. Within the HVAC Control Valves & Actuators category, that translates into products engineered to regulate heating and cooling media with tight tolerances — exactly what building systems and process environments demand.

What Sets Asco Apart in HVAC Valve & Actuator Applications

Asco is the worldwide leader in the design and manufacture of quality solenoid valves, and their products are designed to control the flow of air, gas, water, oil, and steam — the very media that circulate through boilers, chillers, air handlers, and hydronic systems. This breadth of media compatibility makes Asco valves a natural fit for the diverse requirements of modern HVAC installations.

This Emerson powerhouse pioneers high-performance flow control solutions, ranging from hazardous-area RedHat series to ultra-efficient low-power operators. In HVAC contexts, the Red Hat line's robust solenoid construction is particularly valued for reliable open/close actuation in steam heating coils, chilled water circuits, and ventilation damper controls.

Asco's heritage of innovation has resulted in an extensive line of products that range from two-position on/off valves to entire flow control solutions designed to meet the requirements of thousands of customers. For HVAC engineers, this range means the right valve configuration is available whether the application calls for a simple normally-closed shutoff on a steam line or a more complex multi-way arrangement in a variable air volume system.

Engineering Confidence in Every Installation

Asco's commitment to quality and unmatched technical expertise have made them the preferred manufacturer of solenoid valves for many industries. In HVAC specifically, that commitment shows up in consistent coil performance across voltage options — including 24V AC/DC and 120V AC variants — enabling straightforward integration with both low-voltage building automation systems and line-voltage control circuits.

With a massive portfolio of 50,000 variations, Asco provides the critical, SIL-rated precision required for the world's most demanding environments. For facility managers and HVAC contractors, this depth of selection means sourcing a drop-in replacement or specifying a new installation is rarely a compromise — Asco almost certainly has the body material, port size, pressure rating, and electrical configuration needed.

• Media versatility: Rated for steam, hot and chilled water, air, and inert gases — covering nearly every HVAC circuit type
• Voltage flexibility: Available in 24V and 120V configurations to match BAS and line-voltage control systems
• Red Hat series: Industry-recognized solenoid design offering 2-way, 3-way, and 4-way configurations for diverse valve actuation needs
