Pneumatic operated cartridge valves Series 8
2/2-way – Normally Closed (NC)
3/2-way – Normally Closed (NC)
3/2-way – Normally Closed (NC)
Series 8 pneumatic operated valves are particularly suitable for applications requiring high flow combined wtih compact design.
The valve is pneumatic operated by electro-pilots which are dimensioned according to the size.
The cartridge design, which is ideal for manifold assembly, allows to reduce both dimensions and the number of pneumatic connections.
The valve is pneumatic operated by electro-pilots which are dimensioned according to the size.
The cartridge design, which is ideal for manifold assembly, allows to reduce both dimensions and the number of pneumatic connections.
The standard function of the valve is 2/2-way NC.
It can however fulfill the 3/2-way NC function if inserted in a proper seat.

Compact cylinders ISO 21287 Series 32
Single and double-acting, non-rotating, auto-cushioned
ø 12, 16, 20, 25, 32, 40, 50, 63, 80, 100, 125 mm
Series 32 cylinders, thanks to their compactness, are suitable for installation in confined spaces.
Being in compliance with the ISO 21287 Standard, the cylinders Series 32 can be used in conjunction with mountings/accessories suitable with ISO 15552 standard.
Cylinders Aluminium profile Series 61
Single and double-acting, magnetic, cushioned
Standard, low friction, low temperatures and tandem versions
Ø 32, 40, 50, 63, 80, 100, 125 mm
Series 61 cylinders comply with the ISO 15552 standards and can be assembled with the entire range of standard accessories.
A permanent magnet, mounted on the piston in these cylinders, enables information to be received regarding the piston position by means of proximity switches mounted in grooves along the cylinder profile.
These grooves can be covered with a slot cover profile.This cylinder series is equipped with adjustable end-stroke cushioning.
Moreover, they are equipped with a mechanical cushioning in order to reduce the impact of the piston as it reaches the end of the stroke.
Cylinders with integrated guide Series QC
Double-acting, magnetic piston, guided
ø 20, 25, 32, 40, 50, 63 mm
These actuators, suitable for use in very limited space, are available in two versions.
- QCT version: with sintered bronze bushes, suitable when the side loads applied to the cylinder are high.
- QCB version: with linear ball bearings, suitable for high precision and fast cycling applications.
Positioning Feedback Cylinders ISO 15552 Series 6PF
Double-acting low friction, magnetic
Ø 50, 63, 80, 100, 125 mm
Series 6PF pneumatic actuators are equipped with a potentiometric linear position transducer integrated inside the rod.
This type of cylinder allows, along the entire stroke, a constant control of the rod position which is read processing the change of the transducer internal resistance.
The pistons have been equipped with a permanent magnet which enables the use of external end-stroke sensors.
The dynamic seals are specific for low friction.
Thanks to the electrical connection, realized by means of an M12 male electric round connector positioned on the rear head, these cylinders fulfil the standards of IP67 protection class.
Series 6PF cylinders comply with the ISO 15552 standards and can be assembled with the entire range of standard accessories.
They are available with bores from 50mm to 125mm with standard strokes from 50mm to 1000mm with intervals of 50mm.
The sturdy design, the flexible installation and the high performance make Series 6PF suitable for use in applications with tensioning cylinders, positioning cylinders and filling, cutting and measuring systems.
Series 16, 24 and 25 Mini-Cylinders (DIN/ ISO 6432)
Series 16, 24 and 25 mini-cylinders are designed according to the European Standard Specifications CETOP RP52-P and DIN/ISO 6432.The choice of materials and other design features have provided the basis for a complete range of versatile and very reliable cylinders.The precise method of crimping the barrel at the head and cap ensures that all the parts are perfectly aligned. Since the Series 16 and 24 may operate at very high speeds, bumpers are attached to the piston as standard in order to reduce noice and wear resulting from high impact loads. Series 24 and 25 are suitable for mounting magnetic proximity switches.Series 25 has an adjustable pneumatic cushion and a magnetic piston. Various mounting accessories are available to enable the cylinders to function in a variety of applications.
