This makes it suitable for single-acting cylinders and pneumatic pilot signals. The pedal operator allows hands-free control, leaving both hands available for handling workpieces or carrying out machine operations.
Typical applications include workstations requiring hands-free pneumatic control, single-acting cylinders, pilot signals, manual override functions and machine setup operations. The Series 551 range uses G 1/4 connections and is available with different operators and valve functions for different manual-control requirements.
