Sponsored by Page 8 PNEUMATIC BOOSTERS Helpful Application Circuitry One-shot Holding Cycle Here a single tank air-to-oil booster feeds two (2) clamping cylinders. The clamp-off position of the 4-way pneumatic control releases the clamp cylinders and simultaneously opens the pilot-operated check valve allowing oil to flow back into the tank. Booster Becomes a Pump Adding a magnet piston enables position sensing. Electronic sensors can then control a 4-way solenoid valve causing the booster pistons to reciprocate and pump high pressure liquid. Exhaust liquid is returned to the tank’s top port from the driven device. Figure 8 - BA Booster one-shot holding circuit Figure 9 - BA Booster used as pump with Air-Oil tank reservoir
