Product Description
The Festo SE and SEU series are quick exhaust valves designed as screw-in, piloted shut-off valves that enable higher piston speeds on the return stroke of single and double-acting cylinders . By allowing exhaust air to escape directly at the cylinder port, these valves significantly reduce back pressure and improve cycle times. The SEU variant includes a balanced, built-in silencer to minimize exhaust noise, ensuring efficient and quieter system operation .
Key Features & Advantages:
Piloted Shut-Off / Quick Exhaust Function: As a piloted shut-off valve, it allows compressed air to flow freely from the pilot valve to the cylinder while blocking the exhaust path. When the inlet pressure drops, the valve immediately opens a direct, high-flow path from the cylinder to the exhaust port, drastically increasing return stroke speeds .
Screw-in Design with Balanced Noise Emission: This valve is designed for direct installation into the cylinder port (G-thread or NPT). The SEU variant features a built-in silencer that reduces exhaust noise to a manageable level (approx. 85-86 dB(A)), allowing for faster cycle times without excessive noise pollution .
High Flow Rate Performance: Delivers exceptional flow rates to maximize cylinder speed. For example, the G1/4 variant offers flows up to 960 L/min, while the G1/2 variant achieves standard flows up to 4,020 L/min for unloading .
Compact & Robust Aluminium Construction: Features a robust, corrosion-resistant die-cast aluminium housing that is both compact and lightweight (some variants weigh as little as 320g). It is designed for operation in harsh industrial environments .
Wide Operating Range: Designed to perform reliably in demanding conditions, operating at temperatures from -20°C to +75°C and pressures up to 10 bar .
Flexible Port & Thread Options: Available as SE (without silencer) or SEU (with silencer). Supports a wide range of pneumatic connections including G1/8, G1/4, G1/2, and 1/4 NPT, as well as push-in QS options for specific variants .
