Tassalini Pneumatic Butterfly Valves for Food Applications

Tassalini pneumatic butterfly valves are sanitary quarter-turn valves designed for on/off isolation and simple flow diversion in food, beverage, winery, dairy, and clean liquid processing lines. Pneumatic actuation reduces local handling and allows integration with CIP or production line automation.

Construction and Materials

Body / Flanges: AISI 304L or AISI 316L
Disc: AISI 316L
Bolts: AISI 304L
Shaft Slide Rings: PTFE
Finish: 120 grit, Ra approx. 1.01–1.14 μm max

Flanges of the same DN are interchangeable, allowing combinations of ends and different connection standards in the same diameter.

Pressure, Temperature, and Seats

Max Product Pressure: 7 bar
Recommended Operating Pressure: 6 bar
With PTFE Seals: 2 bar max
General Valve Operating Range: -10 to +95 °C

Sealing Options:

Silicone Food Grade: -50 to +200 °C
EPDM: -30 to +140 °C
FTM: -15 to +220 °C
PTFE-coated FTM: -10 to +150 °C
PTFE + Silicone: -10 to +150 °C

Pneumatic Handling

Pneumatic actuators are available in horizontal or vertical configurations, single or double acting, and in a flow control version. They can be equipped with proximity contact, electric or pneumatic microswitch, solenoid valve 24 V AC / 24 V DC / 48 V AC, and connector.

Dimensions and Connections

The pneumatic series covers DN25–DN100 and 1"–4". Available connections: weld end, threaded end, liner + nut, flange, ferrule end. Standards: DIN, SMS, RJT BS, IDF/ISS, BSP, Eno, Macon, Clamp.

FAQ

Is it suitable for throttling?
Only for simple throttling. For precise proportional control, a control valve is required.

What factors are considered in selection?
DN, connection, seat material, CIP chemicals, temperature, pressure, actuator type, and feedback requirement.

Datasheet and documents

Description

Our butterfly valves are manufactured in Aisi 304L and Aisi 316L stainless steel and are obtained from hot-pressed and solubilized parts. The shutters are made from hot-pressed and solubilised Aisi 316L stainless steel parts, mechanically machined on all surfaces and ground on the rotating parts. The standard application of two PTFE bushes on the shafts of the shutters allows to eliminate the friction in the rotations.

The gaskets are produced with compression molding and with excellent quality elastomers. The standard elastomer is food grade silicone; on request, EPDM, FTM, PTFE coated PTFE, PTFE + silicone are available.

All flanges are interchangeable and the valves can be equipped with manual or pneumatic controls.

There is a wide range of manual controls to satisfy the different system requirements; the pneumatic controls can be horizontal or vertical with single acting, double effect and flow regulation, and can be fitted with proximity contact, microswitch, solenoid valve and connector.

Valves are manufactured in the dimensions DN 25 to DN 250 and 1/2″ to 10″.

The standard finish is 120 grit (Ra 1.01-1.14 µm max).

The maximum operating pressure is 7 bars;

2 bars for PTFE seal rings.
