I. Features
The TMR7-L6 control air valve is a series of pneumatic pressure‑regulating, directional valves. Operated manually, by foot pedal, or mechanically, these valves can regulate both air pressure and flow. These functions can be controlled within a single air circuit.
The TMR7-L6 control air valve is a pedal‑actuated three‑way pressure‑regulating valve, designed for installations where the operator stands or where the valve cannot be mounted below ground level. Pressing the pedal increases the outlet pressure, while releasing it decreases the outlet pressure. The pedal returns to its default position automatically.
The TMR7-L6 control air valve is suitable for industrial control applications and any situation requiring foot‑pedal‑based pressure regulation. The P port serves as the input, while the A port functions as the output, delivering stepped pressure that is proportional to the pedal’s downward travel.
