3/2-way – Normally Closed (NC)
Series CFB Stainless Steel direct acting solenoid valves for general purpose, 2/2-way and 3/2-way NC, are the ideal solution for a wide range of applications whereby the environment and fluids used can be particularly aggressive and contaminating.
Special versions are available on demand.
Special versions are available on demand.
The valve function is determined by a poppet and the operation is direct.
Different versions are available according to the nominal diameter and to the threaded ports, as shown in the following tables.
They can thus satisfy various requirements in terms of flow rates and working pressures.

Anti-rotation guide units Series 45
Suitable for cylinders:
- DIN/ISO 6432 (Ø 12, 16, 20, 25 mm)
- ISO 15552, previous DIN/ISO 6431 (Ø 32, 40, 50, 63, 80, 100 mm)
Series 45 guide units can be used with all DIN/ISO 6432 cylinders of Ø 12 ÷ Ø 25 and ISO 15552, previous DIN/ISO 6431, cylinders of Ø 32 ÷ Ø 100.
They have been developed in order to prevent piston rod rotation and can support possible radial loads.
Series 45 guide units are available in three different models depending on the applicable loads.
The UT and HT guides with crawling supports are self lubricating, while HB guides have a ball bush.
To ensure the right choice of the loads in relation to the stroke, please refer to the graphs.
The shorter the stroke the higher will be the applicable loads.
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.
Hydrochecks Series 43
Bore ø 40 mm
Regulated thrust or return stroke
Skip-Stop function
Series 43 hydrocheck units are available with two different types of control: regulated outward movement and fast return; or fast outward movement and regulated return.
These hydrochecks come complete with an oil surge tank which ensures automatic equalisation.
Speed variation is obtained by means of an incorporated flow regulator designed to allow comprehensive and constant use.Upon request, they can be supplied with an incorporated stop valve or an acceleration valve or both.
To restore oil when the minimum level in the surge tank is reached, use the following oil and pump Mod. 43N-PMP:
hydraulic oil, class H, ISO symbol HG 46, viscosity 4.5 E. at 40°C.
Short-stroke cylinders Series QN
Single-acting, non magnetic
ø 8, 12, 20, 32, 50, 63 mm
Series QN single-acting short-stroke cylinders have been designed so that they can be installed in very small spaces.
Due to the compactness and sturdiness of these cylinders, they are mainly suitable for positioning and locking.The available strokes are indicated in the tables.
Stainless steel cylinders Series 97
Single- and double-acting, cushioned, magnetic.
Ø 32, 40, 50, 63 mm
Series 97 stainless steel cylinders can be used in critical applications where a high level of corrosion resistance is required (for example: off-shore, naval, food industries).
These cylinders are normally equipped with end-stroke cushioning which can be adjusted through a screw on the end block.
In order to quieten the impact of the piston on the end block, these cylinders are also equipped with mechanical cushioning.
