A distinction is made between three groups of valves, according to their principle of operation:
Vacuum valves are used to control the vacuum and to improve the process safety in vacuum-gripper systems.

Solenoid valves |
 Inline valves IV
• Nominal diameter 3 mm
• Nominal flow rate 2 m³/h
• Voltage = 24V | The valve for vacuum control directly on the suction pad; Vacuum monitoring is possible directly on the valve. |
 Solenoid valves EMV
• Nominal diameters 3 to 25 mm
• Nominal flow rates 2 to 88 m³/h
• Voltages =/~ 24/230 V | The valve for direct control of vacuum and compressed air. |
 Solenoid valves EMVO
• Nominal diameters 12 to 25 mm
• Nominal flow rates 21 to 101 m³/h
• Voltages =/~ 24/230 V | The valve for high flow rates for direct control of vacuum. |
 Solenoid valves EMVP
• Nominal diameters 10 to 50 mm
• Nominal flow rates 10 to 310 m³/h
• Voltages =/~ 24/230 V | The valve with pneumatic pilot control for vacuum generation. |
Check valves |
 Check valves SVK, SVKG, SVV
• Max. blow-off flow rate 4.8 to 47.4 m³/h
• Connection threads M5 to G1/2” | Check valves close the vacuum line if the suction pad is not covered, thus maintaining the vacuum. The version SVV is adjustable. |
 Check valves SVN
• Max. blow-off flow rate 27 m³/h
• Connection threads G1/4” | The SVN extends the application range of the SKV. It is particularly suitable for dusty surroundings. |
 Flow resistors SW
• Nozzle diameters 0.25 to 2.0 mm | Throttle valves reduce the flow of air in order to prevent break down of the vacuum if some suction pads are not covered. |
Sensing valves |
 Sensing valves TV / TVN
• Flow rate 1.08 to 3.46 m³/h
• Connection threads G1/8” to G1/2” | Sensing valves sense the presence of the workpiece mechanically and then open the vacuum line. |
Non-return valves |
 Non-return valves RSV
• Nominal diameters 6 to 54 mm
• Nominal flow rates 5 to 350 m³/h
• Connection threads G1/4” to G2” | The safety valve with return spring for compressed air and vacuum. |
Manually actuated valves |
 Two-way ball valves KVZ
• Nominal diameters 8 to 50 mm
• Nominal flow rates 5 to 310 m³/h | The manual 2/2-way valve for vacuum and compressed air. |
 Three-way ball valves KVD
• Nominal diameters 6 to 25 mm
• Nominal flow rates 5 to 55 m³/h | The manual 3/2-way valve for vacuum and compressed air. |
 Manual slide valves HSV
• Nominal diameters 7 to 24 mm
• Nominal flow rates 6 to 50 m³/h | The valve for direct control of vacuum and compressed air with frequent actuation. |
 Foot-operated interrupter FU
• Nominal diameter 7.2 mm
• Nominal flow rate 6 m³/h | For foot control of vacuum and compressed air. |
