The BA 730 301 is a manually operated pneumatic valve, 7/3 configuration, designed for front panel installation with a Ø22 mm mounting hole. Hafner technical documentation refers to this as a double 5/2-way valve, meaning it can control two double-acting cylinders from a single rotary actuator.
The BA 730 301 is used where simultaneous or combined control of two double-acting actuators is required from a single panel location. The BA 334 01 lever provides three fixed positions. Although the valve body includes an internal mechanical spring, the actuator uses a detent mechanism, so the selected position is mechanically held until manually changed.
A 7/3 valve is selected when a standard 5/2 valve is insufficient, typically when two independent double-acting outputs are needed from a common actuator. Key parameters include the 280 l/min flow rate, actuator volume, operating pressure, three-position logic, and available space behind the panel.
Typical uses include pneumatic control panels, manual sequencing of two cylinders, service stations, packaging machinery, clamping systems, and applications requiring operator control of two double-acting motions from a single rotary selector.
Routine checks include monitoring for port leakage, compressed air cleanliness, secure panel mounting, correct detent operation, lever wear, and full switching in all positions.
