The precise flow control results in accurate outlet pressure insensitive to inlet pressure, flow rate and temperature. The Marotta 10K electronically controlled pressure regulator’s multifunctionality provides positive isolation and precise flow control and pressure regulation.

For more than 80 years, we have been a trusted supplier to clients including the U.S. Navy and NASA. Our extensive capabilities in engineering, design, analysis, manufacturing and testing ensure we always provide the best control system solutions. This is why we are the only small business to win the coveted NASA George M. Low Award for Quality and Excellence twice.

Regulating valve

The outlet pressure can be varied on command. This gives operators the flexibility they need to accommodate a wide range of applications within their systems.

Backpressure regulator

The hybrid design of the system combines mechanical and electronic pressure control. Transient stability and pressure regulation is handled by the mechanical system. Longer time frame deviations, set point, and output pressure are handled by the electronic control system. This hybrid approach enables very fast, accurate, stable, and scalable operation without large electronic power or control input. Time averaged power draw is less than 10W, and peak draw is less than 45W.

The system consists of a dome loaded regulator with two pilots that can increase or decrease dome pressure as needed during operation. The dome pilot valves are actuated by an electronic control system that constantly measures system output pressure and increases or decreases dome pressure as required to correct for output pressure error

These regulators also have the ability to act as an isolation valve, combining two functions into one device. This increases the functionality and versatility of these devices in your system.

Our rigorous approach to quality control and precision design is what makes our electronic pressure regulators stand out from the competition. With our long history of serving customers in some of the most demanding industries with the most rigid standards, we have developed a reputation for supplying products that deliver the highest levels of performance.

Butterfly valve

These electronic back pressure regulators provide accurate performance and minimal deviation in output pressure regardless of inlet conditions. This means operators can count on them to deliver consistent control and keep their systems flowing as smoothly and efficiently as possible.

Proportional control of pilots enables smoother corrections. Our electronic high-pressure regulators help ensure that your systems function as effectively as they should. This is one of the key reasons why these electronic pressure regulators and other devices are found in highly demanding situations where precision is crucial.

In the event of a regulator fault, these regulators will notify the operator. This means any issues can be dealt with quickly to prevent prolonged system outages.

Marotta’s patented electronic pressure regulator is suitable for spaceflight, defense and facility applications. Through a closed loop electronic control system controlling piezo-actuated pilot valves, the automatic pressure regulator constantly measures actual downstream outlet pressure and adjusts to changing inlet conditions.
