Butterfly Valves

Butterfly Valves
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. Ball valves can be actuated either manually or pneumatically. 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 Ra ≤ 0,8 µm.
The maximum operating pressure is 7 bars; 2 bars for PTFE seal rings.
Pneumatic Butterfly Valves
Pneumatic valves are air operated and designed for shut-off and diversion functions. The wide choice of body combinations allows them to be used as a shut-off valve with two or three ports, or as a diverting valve with three to five ports.
Features Valves series 900 are made in conformity with the 3-A standards criteria, are fully self-draining, easy to sterilize and internal components are easily accessible during CIP process.
Valves can become either normally open or normally closed by simply turning the cylinder upside down.
Valves series 800 offer a wide choice of shutters and gaskets designed for specific system requirements.
Valves are available with single and double-acting actuators, control units and a full range of electrical components.
