These small in-line filters retain impurities and very fine dust, interfering with the capacity in a negligible manner. Thanks to their reduced size, they can be directly installed onto vacuum piping, close to the services (vacuum cups, vacuum clamping systems etc.) for a fractionated filtration and a better visual control of all the plant suction points.

Plunger valves are composed of a cylindrical brass body, a steel plunger with a conical valve and a thrust spring. 
Connected to vacuum, they are normally closed. 
They activate suction, thus creating vacuum, only when the plunger is in contact with the gripping surface. 
They are available in various versions, all suitable for our vacuum cups. 

 It is made using section tubes in special copper alloy, one end is welded to the threaded pin of the vacuum-pressure gauge, thus forming a single body with it, while the other closed end is free As the vacuum or the pressure inside increases, it tends to shift from the initial position (Bourdon effect).

- Extremely reduced size and weight
- Stainless steel stem and spring
- Self-lubricating bush built in the threaded sleeve ensuring a perfect sliding of the stem and durability
- Indicated for Pick & Place units and handling machines for unloading plastic objects from a mould press
- Available in various versions with or without coupling
- Suitable for all vacuum cups with male M5 support 

These traditional cup-shaped vacuum cups are suited for gripping and handling small objects with flat, slightly concave or convex surfaces. This series of widely used cups have diameters ranging from 4 to 9 mm and are normally available in standard compounds: natural para rubber N, oil-resistant rubber A and silicon S.
