Up to 10,000 psi
Marotta’s patented electronic pressure regulator is suitable for spaceflight, defense and facility applications. Through a closed-loop electronic pressure control system controlling piezo-actuated pilot valves, the automatic pressure regulator constantly measures actual downstream outlet pressure and adjusts to varying inlet conditions.
Operating across a range of 0 to 10,000 psi, the MFV400 uses a hybrid mechanical-electronic architecture. The mechanical aspect of the regulator handles fast transient responses, whereas the longer-term pressure correction is provided by the electronic controls. With closed-loop pressure sensing continually measuring downstream pressure, it adjusts dome pressure using piezo-actuated pilot valves to correct errors rather than relying on fixed spring or diaphragm behavior.
The precise flow control results in accurate outlet pressure insensitive to inlet pressure, flow rate and temperature, which is critical in systems that have fluctuating supply conditions. The electronic setpoint control allows for integration into digitally controlled systems, as well. The Marotta 10K electronically controlled pressure regulator’s multifunctionality provides positive isolation and precise flow control and closed-loop pressure regulation. This reduces component count while maintaining control authority without increasing system complexity.

Electronically Controlled, Piezo-Actuated Regulator
The MFV400 high-pressure electronic regulator is a hybrid mechanical-electronic system that provides flexible, accurate, and stable high-pressure fluid regulation across a large pressure ratio.
The hybrid design of this digitally controlled pressure regulator system combines mechanical and electronic pressure control for propulsion systems. Transient stability and pressure regulation are handled by the mechanical system. Longer time frame deviations, set point, and output pressure are handled by the electronic control system. Longer time-frame deviations, set-point adjustments, and output pressure control are handled by the electronic control system. This hybrid approach enables very fast, accurate, stable, and scalable operation without large amounts of electronic power or control input. Time averaged power draw is less than 10W, and peak draw is less than 45W.
The piezo-actuated pressure regulator 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 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.
Technical Specifications
Our electronically controlled valve regulators are built to deliver exceptional control and dependability no matter the application:

- 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 safety-critical pressure regulation 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.
Electronic Pressure Regulator Applications
These regulators are often used in propellant feed systems where precise downstream pressure control is required despite changing upstream pressures. MFV400 allows for continuously variable setpoint control enabling deep throttle control fo spacecraft landing and high Delta-V spacecraft activity. The normally closed design eliminates overtshoot risk typically associated with mechanical regulators and can serve as both isolation and regulation in one package. tank pressures over time, including monopropellant and bipropellant architectures.
These high-pressure control valve assembly solutions also are suitable for test and ground support environments that call for repeatable pressure profiles, electronic setpoint adjustment, and system status output without manual intervention. For aerospace, spaceflight, and defense systems, these regulators provide versatility due to their low average power consumption, onboard control logice and redundant sensing.
