PROGEF Standard Ball Valve type 546 Pro
The PROGEF Standard Ball Valve type 546 Pro is engineered from isotactic Polypropylene Homopolymeride ß-PP-H, ensuring a 25-year operational life in water at 20°C and enhanced chemical resistance. Its true double union design facilitates swift installation and maintenance. PTFE ball seats, paired with EPDM or FKM backing rings, provide self-adjusting seals and consistent operating torque. A safety stem with a predetermined breaking point prevents media leakage, while buttress type union nut threads enable secure, radial mounting/dismounting. Manufactured to EN ISO 16135 and tested to EN 12266 (leak rate A). Ideal for water, wastewater, effluent, and industrial chemical applications.
