Description
The Praher Plastics butterfly valve K4, made of PVC-U, is a robust shut-off valve for swimming pool systems, water treatment, and industrial piping systems. Thanks to its flanged connection compatible with DIN, ANSI, JIS, and BS standards, it can be flexibly integrated into a wide variety of system configurations. The combination of PVC-U, an EPDM seal, and an A4 stainless steel shaft offers high corrosion resistance and is suitable for numerous applications in water technology.
The valve is rated for a pressure class of PN10 and can be automated using electric or pneumatic actuators via the ISO 5211 interface.
