STAR WATER TECHNOLOGY is a recognized leader in the production of high-performance UPVC pipe fittings and valves. Our entry into the plastic injection moulding industry began in 2003. By 2005, with the critical support and expertise of our parent company, GEMAŞ GENEL MÜHENDİSLİK AŞ, we successfully launched the production of our signature UPVC (Unplasticized Polyvinyl Chloride) product line.

Our commitment to UPVC is driven by its exceptional characteristics, which perfectly meet the rigorous demands of high-pressure fluid transfer systems across various sectors:
UPVC offers high mechanical strength and robust quality, ensuring better long-term performance and reliability than many alternative plastics.
We operate within the specialized manufacturing niche of high-pressure UPVC fittings and valves, a focus that ensures deep expertise and consistent quality.
Our components are essential across high-pressure water markets, including agricultural irrigation, industrial water treatment, and general plumbing/construction.
Operating from our headquarters in Izmir, STAR WATER TECHNOLOGY proudly develops and manufactures products under our internationally registered brand, FITVALF.
FITVALF is synonymous with quality and pioneering design. We have demonstrated our commitment to excellence through innovative solutions, notably with our patented ball valves. Our entire production process is certified under the ISO 9001 Quality Management System, ensuring the highest possible standards for every component.
With an integrated facility spanning 4000 sqm and a dedicated team of over 50 employees, our brand continues to achieve increasing market share and recognition in both domestic and international markets.
