FESTO LR-1/2-D-MAXI (186455) High-Flow Pressure Regulator
The FESTO LR-1/2-D-MAXI is a heavy-duty, pilot-controlled piston pressure regulator designed for large-scale pneumatic systems requiring exceptionally high flow rates. As part of the premium D-Series Maxi range, it provides a stable outlet pressure regardless of supply fluctuations, ensuring consistent performance for high-demand actuators and tools.
This regulator features a secondary exhausting (relieving) function, allowing for the rapid venting of downstream pressure when the setpoint is adjusted downward. Its rugged die-cast zinc housing and lockable rotary knob make it an industry standard for safety and durability in harsh manufacturing environments.
