This company’s CV Series valves are capable of continuous operation at pressures up to 20,000 psi. The valve is available as either an on-off position model or a three-way, four-position model. In addition to high pressures, the patented valve design can be used in high-temperature applications and with corrosive fluids. The CV Series valves are pneumatically operated via a set of small, low-voltage pilot valves. The CV valves maintain a constant internal fluid volume and do not trap any fluid within the valve body when switched, the company says. — Vindum Engineering Inc., San Ramon, Calif.
