Festo MS6-LRB-1/2-D6-AS Pressure Regulator

Technical Overview

The Festo MS6-LRB-1/2-D6-AS (Part No. 530328) is a highly reliable directly controlled diaphragm pressure regulator specifically designed for manifold assemblies. It features a G1/2 pneumatic connection, delivering a high standard nominal flow rate of 6,300 l/min. The pressure regulation range covers 0.3 to 7 bar with a maximum pressure hysteresis of just 0.25 bar, ensuring precision control. Engineered with a durable aluminum die-cast housing and an NBR diaphragm, it withstands demanding industrial conditions. The unit includes a lockable rotary knob, an integrated pressure gauge, and primary pressure compensation to maintain constant outlet pressure. With a compact 62mm grid dimension, it perfectly integrates into advanced pneumatic air preparation systems.
