NYSE-listed technology and engineering company Emerson has launched its new ASCO Series 641, 642 and 643 aluminum filter regulators, which maximise process efficiency and reduce unplanned downtime in a broad range of process applications.

This line of durable, aluminum filter regulators can handle the highest flowrates of any regulators in their class and provides precise pressure regulation to downstream instruments, the company says.

An alternative to stainless steel filter regulators, the ASCO Series of aluminum filter regulators complete Emerson’s full suite of valve piloting technologies, which the company says 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.

“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,” Emerson Europe, Middle East & Africa marketing manager Mike Howells says.

He adds that the new ASCO Series simplifies sourcing for customers and ensures that they have “industry-leading technology that enhances process efficiency, safety and reliability”.

With the market’s highest flowrate capabilities up to 370.8 ft³/m, the aluminum filter regulators improve process efficiency and ensure that stringent process valve opening/closing requirements like those for emergency shutdown valves are met.

Higher flowrates 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 specialised powder coating ensures reliable operation in harsh, corrosive process environments.

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 customisable, Emerson adds, noting that 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.
