Festo SEU-1/8 Quick Exhaust Valve G1/8 550L/min 10bar 4616

Overview
The Festo SEU-1/8 (part number 4616) is a high-performance quick exhaust valve from the SEU series, designed to significantly increase the piston speed of single-acting and double-acting pneumatic cylinders on the return stroke. By allowing exhaust air to be released directly to the atmosphere through a large cross-section, this valve bypasses the slower path through the control valve, enabling much faster cylinder cycling.

The valve features a compact design with G1/8 pneumatic connections on both ports 1 and 2, and a built-in silencer (muffler) on port 3 to reduce exhaust noise. The silencer lowers the sound pressure level to 85 dB(A). It is constructed from a durable die-cast zinc housing with NBR seals, offering robust protection for demanding industrial environments. The valve can be mounted in any position.

The SEU-1/8 operates over a pressure range of 0.5 to 10 bar and a temperature range of -20°C to +75°C, making it suitable for a broad range of industrial conditions. It has a nominal width of 5 mm, a standard nominal exhaust flow rate (6→5 bar) of 550 l/min, and a maximum exhaust flow rate (6→0 bar) of 1,000 l/min. It is also ATEX certified for use in potentially explosive atmospheres, and RoHS compliant, meeting environmental standards.

Key Features

• Quick Exhaust Function – Significantly increases the piston return speed of single-acting and double-acting cylinders by providing a direct, high-flow exhaust path to atmosphere.

• Built-in Silencer – Reduces exhaust noise to a sound pressure level of 85 dB(A), creating a quieter and safer working environment.

• G1/8 Pneumatic Connections – Standard threaded G1/8 ports (Port 1 and Port 2) for easy integration into existing pneumatic systems.

• High Flow Capacity – Delivers a standard nominal flow rate of 550 l/min (6→5 bar) and a maximum flow rate of 1,000 l/min (6→0 bar), ensuring rapid cylinder cycling.

• Wide Operating Range – Reliable operation with an operating pressure range of 0.5 to 10 bar and an ambient/medium temperature range of -20°C to +75°C.

• Robust Construction – Durable die-cast zinc housing and NBR seals provide excellent corrosion resistance and longevity in harsh industrial environments.

• Direct Cylinder Mounting – For optimal performance, the valve should be connected directly to the cylinder port to maximize the quick exhaust effect.

• ATEX Certified – Approved for use in potentially explosive atmospheres, increasing application versatility.

• Original Brand New, Within Warranty Period – Genuine Festo product, brand new in sealed packaging, covered by manufacturer's warranty.

• 100% Satisfaction Guarantee – Your purchase is protected by our satisfaction guarantee; return or exchange if not completely satisfied.
