HoKa control flap / control butterfly valve with socket or flange, plastic molded part round with internal stop for connecting pipes in an exhaust air system using a welding process. As a control flap for adjusting the volume flow, internal diameter of the socket based on DIN 8062. Manufacturing process: made from semi-finished products. Possible negative overpressure on request after mechanical, chemical and thermal stress.
The use of thermoplastic polymers in ventilation systems has a long tradition. The application fields continued to expand for many decades, especially due to the positive experiences in terms of workability, chemical resistance and operating efficiency. Because of the outstanding properties of the individual plastic materials, ventilation systems made of synthetic materials can be used almost everywhere.
Classical application fields are:
- Chemical industry
- Clean room industry
- Surface fi nishing (caustic, electroplating)
- Chlorine industry
Nowadays, these fi elds can be easily equipped with plastic pipes
