Product Description
The Festo GRU and GRE are screw-in exhaust air flow control valves that combine flow control and silencer functions in a single compact unit, designed to be mounted directly onto the exhaust ports of pneumatic directional control valves . By controlling the exhaust flow rate, these valves enable precise adjustment of piston speed, with the GRE version utilizing a sintered metal muffler and the GRU version employing a polymer design .
Key Features & Advantages:
Integrated Exhaust Silencer Function: Both series incorporate a built-in muffler that dampens exhaust noise while simultaneously providing flow control, eliminating the need for separate components and reducing installation complexity .
GRU Flow Control/Silencer – Polymer Design: Features a lightweight polymer muffler construction, delivering high flow rates up to 8,000 L/min (G3/4 version) with a PA adjusting screw and die-cast aluminium housing .
GRE Exhaust Air Flow Control – Sintered Metal: Utilizes a durable sintered metal silencer element, providing robust performance for demanding industrial environments with a brass adjusting screw and wrought aluminium alloy threaded plug .
Precise Slotted Head Screw Adjustment: Both series feature a slotted head screw as the adjustment component, allowing tool-based fine-tuning of the exhaust flow rate to precisely control cylinder piston speed .
Wide Operating Range & Corrosion Resistance: Operates across an ambient and medium temperature range of -10°C to +70°C with an operating pressure up to 10 bar . NBR seals and RoHS-compliant materials ensure reliable long-term performance in various industrial environments .
