JANATICS GV21M and GV21 Series Pilot Operated Non-Return Valves are designed to lock pneumatic cylinders in position and prevent reverse airflow when the pilot signal is removed. These valves allow free airflow in both directions while pilot pressure is applied and automatically function as a check valve when the pilot signal is absent, ensuring safe and reliable cylinder holding. They are widely used in pneumatic automation systems for load holding, safety circuits, and intermediate cylinder positioning
