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.
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 supplier.
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.
With the market’s highest flow rate capabilities of up to 370.8 standard cubic feet per minute (10,500 liters per minute), Emerson's aluminum 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.
