Butterfly flaps (valves) can be used to cut or start material flow in industrial applications and for proportional flow control purposes. It is generally used under the silos, at the inlet and outlet points of the systems such as free flow strains, bigbag unloading systems, bag breaking systems. The inner part is sealed to ensure tightness. In the applications where the food must be compatible, the disc part is made of stainless steel gasket food compatible material.
- The butterfly flaps are manufactured as welded with carbon steel, stainless steel and high hardness.
- 95% metal metal sealing is provided.
- Depending on the use, butterfly valves are available with single and double flanges.
- Commonly used butterfly valves for fluid control consist of shaft, stem and elastomer seal. The butterfly valves are designed using the latest facilities of today’s technology.
- The valve disc opens or closes the orifice where the flow passes through the shaft.
- In addition to the fact that the butterfly valve body is more resistant to atmospheric conditions, the butterfly valve provides much more resistance to material stresses and extends the service life of the butterfly valve.
- The selection of the valve and the elastomer seal should be made according to the fluid. As the elastomer gasket, EPDM, NR, NBR, FKM, PTFE material selection may be preferred.
- The opening and closing process can be done by pneumatic actuator or manual lever.
- The maximum (maximum) working pressure is 200 mbar (0.2 bar),
- Butterfly Flaps are used in all kinds of construction material processing plants which need to keep dry materials fed by their own weight. These flaps attach to the bottom of bunkers, warehouses or silos. Due to their special designs and the material they are used, they are a very economical and efficient solution for many years.
