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.
