Butterfly valve 4900

manualfor the chemical industryfor the food industry

Sandwich butterfly valves, whether manually or automatically operated, can be used in most liquid product applications in the food-processing, pharmaceutical and chemical industries. The design allows to easily instal or remove the valve without separating the pipes. The butterfly valve can be operated automatically through an actuator or manuallywith a handle. The handle blocks the valve in the "open" or "closed" position, although there are alsoother models with intermediate positions.The actuator transforms the axial movement of the piston into a 90º rotary movementwhich it transmits to the disc. Design: "between flanges". 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". Low pressure losses. Bodyhalves 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 according to FDA 177.2600 Internal surface finish: Ra ≤ 0,8 μm External surface finish: Machined, Ra ≤ 1,2 μm AISI 304L valve. Gaskets: NBR, VMQ or FPM. Two sizes for two-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).
