Emerson has launched its new ASCO™ Series 641, 642, and 643 aluminum filter regulators, which maximize process efficiency and reduce unplanned downtime in a broad range of process applications. This line of durable, aluminum filter regulators can handle the highest flow rates of any regulators in their class and provides precise pressure regulation to downstream instruments.

ASCO Series

An alternative to stainless steel filter regulators, ASCO Series 641, 642, and 643 aluminum filter regulators complete Emerson’s full suite of valve piloting technologies. This allows process manufacturers to source their total valve piloting solutions, including solenoid valves, switch boxes, filter regulators and accessories, from one global technology partner. 

By using one supplier, manufacturers can simplify their supply chains, improve design accuracy, and access comprehensive engineering support. Designing a valve piloting solution that includes technologies from different suppliers splits vendor responsibility and can introduce an opportunity for error.

Designing a valve piloting solution that includes technologies from different suppliers

Sourcing valve piloting technology from multiple vendors is time-consuming and complicates supply chains, while limited options for conventional filter regulators leave some customers with unmet needs,” said Mike Howells, Marketing Manager, process applications for Europe, Middle East & Africa at Emerson.

He adds, “Our new ASCO Series 641, 642, and 643 Aluminum Filter Regulators simplify sourcing for our customers and ensures that they have industry-pioneering technology that enhances process efficiency, safety and reliability.”

robust filter regulators

With the market’s highest flow rate capabilities of up to 370.8 standard cubic feet per minute (10,500 liters per minute), the aluminum filter regulators improve process efficiency and ensure that stringent process valve opening/closing requirements like those for emergency shutdown valves are met.

Depending on the application, slow valve closures can increase safety risks

Higher flow rates provide more air to the valve actuator, which increases the opening and closing speed of process valves. Depending on the application, slow valve closures can increase safety risks.

These robust filter regulators feature rugged construction and advanced engineering that further enhance safety and maintain plant uptime, while specialized powder coating ensures reliable operation in harsh, corrosive process environments.

three-tiered regulator line

Effective moisture removal keeps media dry to protect downstream devices, and sophisticated media filtration prevents downstream process contamination.

This three-tiered regulator line provides a 0.25-inch to 1-inch coverage and is highly customizable. Process manufacturers can choose advanced features such as Quick Relief, which enhances safety and operational certainty by exhausting downstream pressure if supply air pressure is lost, as well as low-temperature and low-copper variants, manual and automatic draining, global certifications, and many other options that serve specific applications, in the chemical, oil and gas, energy and utilities, food and beverage, and water and wastewater industries.
