Product Description
The Festo LRL and LRLL series are differential pressure regulators featuring a piston regulator design with through pressure supply, maintaining a constant pressure differential between input and output regardless of inlet pressure fluctuations . Designed without secondary exhaust and without pressure gauge, these compact regulators can be mounted vertically or horizontally with 360° rotatable connections, making them highly versatile for precise differential pressure control in pneumatic systems .
Key Features & Advantages:
Constant Pressure Differential Between Input and Output: Maintains a manually set differential pressure (Δp) independent of fluctuating primary pressure, ensuring stable 2–6 bar pressure regulation range .
Piston Regulator with Through Pressure Supply: Robust piston design with continuous pressure supply ensures reliable operation and high flow rates up to 700 L/min (1/2 size) .
Integrated Check Valve for Exhaust Function: Built-in check valve allows pressure at the push-in connection to escape without affecting the connecting thread pressure, enabling return flow capability despite no secondary exhaust .
Flexible Connection Configurations: Available with thread/push-in connector combinations on top or side, supporting thread sizes from M5 to G1/2 and push-in sizes from QS-4 to QS-12 .
Compact 360° Rotatable Design: Very small footprint with fully rotatable connections allows flexible installation orientation and easy integration into space-constrained pneumatic systems .
