Direct acting solenoid valves Series PD
2/2-way – Normally Closed (NC)
The Series PD directly operated solenoid valves are available in the 2/2-way normally closed (NC) version. Pneumatic interfaces allow installation on manifolds in horizontal or vertical position. Also available with threaded connections.
Please note that all Series PD solenoid valves are supplied with direct current (DC).
To operate in alternating current (AC), it is necessary to use the connector with bridge rectifier Mod. 125-900.

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.
Compact cylinders Tandem and Multi-position versions Series 32
Double-acting, magnetic
ø 25, 40, 63, 100 mm
Thanks to their great compactness Series 32 cylinders, Tandem and Multi-position, are suitable to be installed within confined spaces and can be used with the same mounting elements of other standard cylinders ISO15552.
The Tandem version enables to obtain up to 2 times the thrust force of a normal cylinder (standard traction force), while the Multi-position version can obtain up to three positions with one cylinder only.
Cylinders with integrated guide Series QCTF – QCBF
Double-acting, magnetic, with double bearings and flanges
Ø 20, 25, 32, 40 mm
These cylinders have been designed to be used in applications where space is limited.
Regarding the bearings, the Slide Units are available in two versions, one with double sintered bronze bushes (Mod. QCTF) and the other with double linear ball bearings (Mod. QCBF).
The QCTF version would normally be selected when the side loads applied to the slide unit are high. Mod. QCBF is suitable for fast cycles (less side load) and higher precision.
The end cushioning is available in three different variants:
- Fixed mechanical cushion (standard);
- With two shock absorbers located on the body;
- With one shock absorber located central on the rear flange.
Series 16, 23, 24 and 25
Series 16: Ø 8, 10, 12 mm - non-magnetic
Series 23: Ø 16, 20, 25 mm - magnetic, auto-cushioned
Series 24: Ø 10, 12, 16, 20, 25, 32 mm - magnetic
Series 25: Ø 16, 20, 25, 32 mm - magnetic, cushioned
Series 16, 23, 24 and 25 mini-cylinders are designed according to ISO 6432. It is possible to choose from three different types of cushioning: mechanical (standard bumper on Series 16 and 24), adjustable pneumatic cushioning (Series 25) and pneumatic auto-cushioning (Series 23).
This last version, thanks to a patented system, automatically adjusts the cushioning in order to provide optimal deceleration during the entire cushioning phase.
The cylinder enjoys smooth, jolt-free movement, reducing vibrations and noise, while also guaranteeing high reliability and constant performance over time.
The adopted technical solutions and the choice of materials have provided the basis for a complete range of versatile and very reliable mini-cylinders.
They are suitable to be used in a multitude of industrial applications, especially where operating conditions undergo changes over time like for example wear of machine components.
Various mounting accessories are available to fix the cylinders in different ways.
