ValveFlow is a company based out of central England, currently involved in contractual manufacturing for a couple paintball companies in addition to other companies.. This company is ran by some former members of Evolve UK from the years of 2002-2006, although the machine shop is relatively new to the design company. At the time of this writing, ValveFlow manufacturers parts for the Vanguard Demon and J4 Torque markers in addition to the other work they perform.
