BUTTERFLY VALVES

Butterfly valves, whether manually or automatically actuated, can be used in most liquid product applications in the food-processing, pharmaceutical and chemical industries.

Operating principle :

– The butterfly valve can be operated automatically through an actuator or manually with a handle. 
– The handle blocks the valve in the “open” or “closed” position, although there are also other models with intermediate positions.
– The actuator transforms the axial movement of the piston into a 90º rotary movement which it transmits to the disc.

Design and features :

– Compact and robust design.
– Multi-position handle as standard feature for valves up to DN-100/4″.
– Two-position handle as standard feature for valves starting from DN-100/4″.
– Several models of easily interchangeable manual handles and pneumatic or electric actuators.
– Low pressure losses.
– Body halves interchangeable with any connection type.
– Connections: DIN 11850.
– Traceability of components.

Materials:

– Disc and body halves: AISI 316L (forged)
– Handle: AISI 304 / PP
– Other st.st. parts: AISI 304
– Gasket: EPDM according to FDA 177.2600 
– Internal surface finish: Ra ≤ 0,8 µm
– External surface finish: Machined

Options :

– Valve in AISI 304.
– Gaskets: NBR, VMQ or FPM. 
– Connections: Clamp, SMS, RJT, FIL-IDF, etc.
– Two sizes for multi-position handle.
– Handles: two-position, lever, micrometric, with safety lock, etc.
– Electric actuator or single- or double-acting actuator, the size is determined by the operating torque of the valve.
– Electro-pneumatic positioner. 
– Inductive position sensors.
– C-TOP control unit (inductive position sensors or microswitches).
– ATEX version available.
