Product Description
The Festo GRxA and GRxZ series are one-way flow control valves that have proven themselves time and again for precise flow rate adjustment, combining a flow control valve with a piloted check valve in a single unit . The polymer-metal combination makes these valves lightweight, compact and sturdy, with availability in standard, mini, and in-line variants across polymer, metal, or stainless steel designs to suit diverse application requirements .
Key Features & Advantages:
Functional Combination of Flow Control and Piloted Check Valve: Integrates a one-way flow control valve with a piloted check valve, allowing flow restriction in one direction while providing free flow in the opposite direction with an additional pilot-operated locking function for enhanced pneumatic circuit control .
Proven Precise Flow Rate Adjustment: Tried and tested design delivers exceptional accuracy in setting cylinder speeds, enabling smooth and repeatable motion control for both advancing and retracting pneumatic actuators .
Lightweight, Compact and Sturdy Construction: The innovative combination of polymer and metal materials results in a valve that is both light and compact while maintaining robustness and durability for demanding industrial environments .
Multiple Material and Variant Options: Available in polymer, metal, or stainless steel designs with standard, mini, and in-line variants offering different flow rates, allowing selection based on environmental requirements and application needs .
Versatile Connection Configurations: Supports connections with thread at both ends, push-in connector at both ends, or thread/push-in connector combinations, providing flexible integration into existing pneumatic systems .
