Butterfly valves, whether manually or automatically operated, can be used in most liquid product applications in the food-processing, pharmaceutical and chemical industries
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.
Disc and body halves: AISI 316L (forged) – Handle: AISI 304 / PP – Other st.st. parts: AISI 304 – Gasket: EPDM FDA .
Internal surface finish: Ra ≤ 0,8 μm – External surface finish: Machined
Valve: AISI 316L or 304L – 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).
