Ball valve type 546 PVC-U With threaded sockets Rp

  Data sheet.pdf

The Georg Fischer Type 546 PVC-U ball valve with parallel female threaded sockets Rp is an industry benchmark for isolation and flow control in demanding fluid handling applications. Engineered for rigorous industrial, chemical, and water treatment operations, this true union ball valve delivers outstanding operational reliability across working pressures up to 16 Bar (PN16) at a reference temperature of 20 degrees Celsius. Designed with parallel female threaded sockets adhering to ISO 7-1 and EN 10226-1 standards, it enables secure, direct mechanical connection to threaded metallic or plastic pipework without requiring solvent cement jointing on site.

Manufactured from premium unplasticised polyvinyl chloride (PVC-U) compound in RAL 7011 grey, the valve body and internal ball demonstrate exceptional resistance against chemical attack from inorganic acids, alkalis, mineral salts, and aggressive treatment chemicals in compliance with ISO/TR 10358 guidelines. The Type 546 operates effectively within a broad thermal window spanning from 0 degrees to +60 degrees Celsius, ensuring superior dimensional stability, low thermal conductivity, and long-term mechanical strength. The low-friction PTFE ball seating surfaces paired with high-integrity elastomeric backing seals—available in EPDM or FPM—guarantee bidirectional bubble-tight shutoff while maintaining minimal operating torque throughout extensive duty cycles.

The true union configuration incorporates robust retaining nuts and integrated backing stops, allowing quick radial installation, maintenance, or replacement directly inline without disrupting adjacent pipe segments. The ergonomic manual hand lever features an integrated tool specifically designed to adjust the ball carrier and union nuts with precision, eliminating the risk of overtightening or thread damage. As an authorised Georg Fischer distributor, BigWeld supplies industrial piping systems across Europe and fabricates thermoplastics where metal fails.
