Vacuum Check Valve SVK With Brass Ball Seat Aluminum Shell Material
1. Introduction and application
Check valves close the vacuum lines of uncovered suction cups. This maintains the system vacuum. Flow restrictors constrict the vacuum line. They are used predominantly in the handling of porous parts.
- For applications with multiple suction cups in vacuum systems,it prevents the effects of suction cups that are not in contact with the workpiece or suddenly come off the workpiece；
- The same gripping system can handle workpieces of different shapes and sizes, so that the gripping system can be repeatedly applied to different occasions；
- Check valves for handling porous workpieces；
- Ball seat valve
- Brass ball seat and aluminum shell with compact structure.
- Suitable for installation in any orientation
3. Advantages
- Closing of inapplicable vacuum suction cups to maintain the system vacuum;
- Low leakage rate which can be compensated with the aid of a bypass;
- Can be connected to all common suction cups and plates.
