VOST Flow-Control Valve, Phase II

Completed Technology Project

Project Introduction

VOST Flow-Control Valve, Phase II
Two cryogenic flow-control valves of diameters 1/2" and 2" will be built and tested. Based on cryogenically-proven Venturi Off-Set Technology (VOST) they have no stem-actuator, few moving parts, and an overall cylindrical shape. Intended to demonstrate a breakthrough in cryogenic flow control, VOST provides precise linear flow control across its entire dynamic range, holds position without power and requires low actuation energy.
