Up to 10,000 psi
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.
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.

Electronically Controlled, Piezo-Actuated Regulator
The MFV400 electronic pressure regulator is a hybrid mechanical-electronic system that provides flexible, accurate, and stable pressure regulation across a large pressure ratio.
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

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.
Technical Specifications
Our electronic regulators are built to deliver exceptional control and dependability no matter the application:
- Constructed of titanium, they are capable of functioning under pressures between 0 and 10,000 psi.
- Can handle fluids with a temperature of up to 157 degrees Celsius.
- Response time of less than 250 milliseconds.
Design Features
Output Pressure Error Correction:
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.
Flexible Set Point:
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.
Output of System Status:
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.
Redundancy:
The failure of one transducer will not result in failure of the system. It isn’t until there is a failure of two or more transducers before the regulator is closed.
Normally Closed
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.
Fluid Compatibility:
Compatible with earth-storable propellants N2O4 and MMH and less-aggressive fluids, our components are capable of handling a wide range of applications. Reach out to one of our representatives to learn more about what they can do for you.
Piezo Actuated Pilots:
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.
