Control -- it's all in the valves at Jet Research, dba Valve Research & Manufacturing. The company designs and manufactures an array of industrial precision valves, from check to solenoid, and related devices, including flow regulators, pressure reducers, and manifolds. Its lineup is one of the most frequently used types of pneumatic control in aerospace, oceanographic, and offshore oil exploration equipment. The company's solenoid valves, for example, are vital to the fuel control system on Boeing's commercial aircraft. Its hydraulic valves help drive military crawlers, and its landing gear valves, Beechcraft's turboprop-powered planes. Started in 1975, Jet Research is led by founder and president, Paul Cruz.
