Overview
The Festo LR-1/8-D-7-MINI pressure regulating valve is a directly actuated diaphragm regulator engineered for demanding pneumatic applications. Part number 162582, this mini-size valve maintains constant output pressure with primary pressure compensation and secondary venting, making it ideal for systems requiring stable, repeatable pressure regulation independent of input pressure fluctuations.
Key Features
- Directly actuated diaphragm design — fast response and reliable pressure control
- Primary pressure compensation — maintains constant output pressure despite input variations
- Secondary venting function — allows exhaust of pressurized output back to atmosphere
- Dual pressure gauge connections — supports dual gauge installation options for monitoring
- Lockable rotary knob with detent — prevents unintended pressure adjustment
- Compact mini-size form factor — space-efficient installation in confined panels
