Aluminium filter regulators enhance process efficiency

Emerson has launched its new ASCO Series 641, 642 and 643 aluminium filter regulators, which maximise process efficiency and reduce unplanned downtime in a broad range of process applications.

This line of durable, aluminium filter regulators are said to handle the highest flow rates of any regulators in their class and provide precise pressure regulation to downstream instruments.

An alternative to stainless steel filter regulators, ASCO Series 641, 642 and 643 aluminium 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.

“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 for process applications for Europe, Middle East and Africa at Emerson. “Our new ASCO Series 641, 642 and 643 aluminium filter regulators simplify sourcing for our customers and ensure that they have industry-leading technology that enhances process efficiency, safety and reliability.”

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