Product Description
The Festo GR Series is a versatile shut-off/flow control valve in a sturdy plastic or robust metal* design, combining a non-return valve and a flow control valve in a single unit for in-line installation. It allows for the separate adjustment of flow and return speeds on single or double-acting cylinders, providing precise pneumatic control by restricting flow in one direction while allowing free flow in the opposite direction.
Key Features & Advantages:
Non-Return and Flow Control Valve: Integrates flow control with built-in non-return function in one housing, allowing separate adjustment of cylinder advance and retract speeds while preventing unintended backflow.
In-Line Installation with Sturdy Construction: Designed for reliable in-line installation directly into tubing runs, featuring a heavy-duty PA-reinforced polymer design or wrought aluminum alloy construction* for durability in demanding environments.
Precise Knurled Screw Adjustment: Features a knurled screw as the adjustment element, allowing tool-free manual actuation for fine-tuning flow rates with ease and precision.
Flexible Mounting Options: Supports optional mounting methods including front panel mounting or mounting via through-holes, providing versatility for different system configurations.
ATEX Hazardous Location Certified: Select variants are ATEX certified for use in Zone 1, 2, 21, and 22 explosive atmospheres, making it suitable for hazardous area installations.
Wide Operating Temperature & Pressure Range: Operates reliably across temperatures from -20°C to 60°C and pressures from 0.2 bar to 10 bar, with some variants operating down to -20°C for cold environments.
