What does a quick exhaust valve do in a pneumatic system?
A quick exhaust valve speeds up actuator motion by venting air directly to atmosphere near the cylinder, instead of sending it back through the control valve and tubing. This reduces backpressure and improves cycle times.
Where is this valve typically installed?
It is commonly fitted close to the actuator port (for example, on a pneumatic cylinder) so the exhaust air has the shortest possible path to vent, maximizing the quick-exhaust effect.
What pneumatic connections does it use?
This version uses G1/8 threaded pneumatic connections on port 1 and port 2, designed for screw-in installation.
Does it include exhaust noise reduction?
Yes. The SEU series unit is supplied with an integrated silencer (muffler) to help reduce exhaust noise during venting.
What is the operating pressure range?
The operating pressure range is 0.5 to 10 bar.
What temperature range can it operate in?
Ambient and operating medium temperature range is -20°C to +75°C.
What compressed air quality is recommended?
It is intended for compressed air in accordance with ISO 8573-1:2010 class [7:4:4]. Using appropriately prepared air helps maintain consistent performance.
Is lubricated operation permitted?
Yes. Lubricated operation is possible; however, if lubrication is used, it should be maintained continuously, as the valve is intended to keep running with lubrication once introduced.
What flow rates can be expected?
Typical standard nominal flow figures are approximately 550 l/min for exhaust (6 to 5 bar), up to 1000 l/min for exhaust (6 to 0 bar), and about 300 l/min for pressurization (6 to 5 bar). Actual performance depends on installation and system conditions.
Can it be mounted in any orientation?
Yes. The mounting position is optional, allowing installation in the orientation that best suits the machine layout.
What materials are used for the body and seals?
The housing is die-cast zinc and the seals are NBR.
Is the valve suitable for PWIS/LABS-sensitive applications?
It is specified as LABS (PWIS) conforming to VDMA 24364-B1/B2-L.
