Description

The Praher Plastics butterfly valve K4 is a manually operated shut-off valve for applications in swimming pool technology, water treatment, and industrial piping systems.

Thanks to its flanged connection compliant with DIN, ANSI, JIS, and BS standards, the valve can be integrated into various piping and system configurations. The combination of PVC-U, an EPDM seal, and an A4 stainless steel shaft is designed for applications in water technology.

Via the ISO 5211 interface, the butterfly valve can be equipped with electric or pneumatic actuators as needed.
