Two in-line single manifolds have been added to the EV/ET valve line from Clippard Instrument Laboratory Inc., Cincinnati. The manifolds mount to 18-NPT ports and couple with EVB-3 boosters to provide increased flow. The 15490-20 Valve Pilot Adapter may be installed in a cylinder port for efficient interface with electronic circuits. EC, EV, or ET valves, controlled by an electronic signal, can be used with the adapter to pilot larger air-piloted valves through 18-NPT outlets. The 15490-10 in-line valve manifold can be installed in 18-NPT supply ports and provide rigid mounting for EC, EV, or ET valves with 10-32 threaded outlet ports.
