E-Drive: Electromagnetic Zero-Emission Valve Drive

This project aims to advance and commercialize an innovative electromagnetic zero-leak, hermetically sealed valve drive capable of actuating various cryogenic valves. The technology eliminates 100% of the valve stem leaks and enhances efficiency, reliability and longevity of valve systems by removing moving parts exposed to extreme, dusty or regolith environments. Additionally, it can be applied to couplings, providing a superior alternative in extreme environments. MagDrive’s patented magnetic actuation, partially funded by NASA, enables zero-emission hermetically sealed valve stems, protecting valve parts from contamination and degradation. The magnetic actuation eliminates dynamic seals, preventing leak paths at any temperature or pressure. This is critical for cryogenic fluid management in diverse environments, from space to surface applications. With E-Drive actuation energy is transmitted through a solid wall from an external electromagnet to an inner magnetic cartridge. The wall encapsulates the stem eliminating dynamic seals and the leak path. E-Drive is compatible with legacy valve systems and standard valve types and sizes used in cryogenic and other target industries. Additionally, this innovation reduces overall size requirements and weight of long stem offsets in cryogenics, addressing the industry's miniaturization focus and aerospace payload considerations. Funds will be used to: 1. Incorporate NASA’s performance requirements and produce a preliminary mechanical design. 2. Develop models to predict valve performance under different conditions. 3. Deliver a 3D CAD prototype E-Drive for virtual performance testing of CV curve, speed, and power and torque requirements. And providing the foundation for the Phase II physical prototype and testing. Target markets include NASA, the commercial cryogenic industry, and sectors requiring high-reliability cryogenic fluid management, commercial aerospace, oil and gas, petrochemical, and chemical industries.

For NASA, the incorporation of leak-free magnetically actuated valve drives with no external moving parts would be a transformative solution to many critical aerospace applications. In cryogenic environments, where the harsh extremities of cold exacerbate the likelihood of part failures and leaks, these valve drives emerge as indispensable components, offering unmatched reliability, efficiency and longevity. Particularly crucial in the storage and handling of cryogenic propellants vital to space missions, their zero emission design ensures the utmost integrity of systems, mitigating the specter of catastrophic failures that could jeopardize entire missions. Refueling stations, operating within the unforgiving vacuum of space, demand absolute containment to avert the potentially devastating consequences of leaks, making leak-free valves an imperative feature. Onboard vessels, navigating the treacherous expanse of space, confront heightened risks stemming from leaks of hazardous materials; thus, leak-free valves serve as an indispensable shield against such perilous scenarios. Pressurizing fuel tanks, operating under extreme temperatures and pressures where traditional valves often falter, benefit immeasurably from the reliability of zero-e magnetically actuated valves. Additionally, fuel lines, susceptible to catastrophic leaks that could spell disaster, find enhanced safety and security with the application of these hermetically sealed valves. Moreover, launch pads, with their environmental hazards arising from chronic leaking valves, witness profound enhancements in safety, efficiency and sustainability with the seamless integration of zero emission electromagnetic valve drives into their operational framework. Wherever leaking valves present looming risks to both mission success, safety, or environment, the application of the hermetically sealed MagDrive E-Drive, offers unparalleled critical solutions for NASA's aerospace pursuits. The integration of zero-emission magnetically actuated valves heralds a new era of safety and reliability across critical aerospace applications for organizations like Blue Origin, SpaceX, and Lockheed Martin, as well as the industrial cryogenic valve market including the emerging Hydrogen infrastructure market. In cryogenic settings, where frigid temperatures amplify the risk of leaks, there are no packing solutions that are 100% leak free. However, this innovation hermetically seals the stem incorporating automated electromagnetic actuation and shrinking the entire assembly’s footprint, weight, and number of moving parts all while eliminating the leak path to atmosphere, providing unmatched performance, reliability and resilience. The E-Drive can play a pivotal role in the storage and handling of cryogenic materials and fuel crucial for space missions, ensuring the integrity of systems. Refueling stations, located within the unforgiving vacuum of space, necessitate absolute containment to prevent potential disasters, making leak-free valves indispensable. Many valves fail due to debris gumming up actuator moving parts and stem packing. This alternative eliminates external moving parts for the actuator and hermetically seals the valve with no dependency on dynamic seals and packing. In petrochemical and other plants, most valves are replaced during turnarounds every 4 to 7 years, with chronic leakers like control valves replaced more often. Plants can have 10,000 to over 300,000 valves. Customer discovery in the oil & gas, petrochemical, refinery, and chemical sectors indicates strong interest in MagDrive’s E-Drive Zero-Emission Valve solution for cost savings on LDAR (Leak Detection and Repair), monitoring, reduced maintenance, increased safety, extended valve life, and reduced downtime. The technology eliminates packing adjustments, ensures consistent torque, and protects valve internals from over-torquing through precise calibration and infinite sheer.
