Engineered for maximum reliability, safety, and precise pressure management under demanding operational conditions in Turkey.
As a critical bridge between Europe, Asia, and the Middle East, Turkey has rapidly expanded its industrial footprint. Major hubs such as the Gebze Organized Industrial Zone (GOSB), Aliağa's petrochemical clusters, and the intensive manufacturing corridors of Bursa and Konya demand high-integrity safety systems. In these high-pressure environments, the role of a reliable Pressure Relief Valve (PRV) is paramount to preventing catastrophic system failures.
With massive investments in natural gas transit pipelines (such as TANAP and TurkStream), municipal water infrastructure upgrades overseen by the State Hydraulic Works (DSİ), and the expansion of geothermal power plants in the Aegean region, Turkey's engineering standards have aligned strictly with European CE norms, EN ISO 4126, and ASME codes. Zhejiang Maria Valve Co., Ltd. delivers custom-engineered pressure relief solutions that perfectly comply with these local regulatory frameworks and demanding operating environments.
Our valves undergo rigorous testing to ensure full compliance with Turkish Standards Institution (TSE) requirements and European Pressure Equipment Directives (PED).
Specially formulated alloy valves designed to withstand high-temperature steam and corrosive brine typical of Turkey's geothermal fields.
How Zhejiang Maria Valve is leading the transition toward smart, sustainable, and high-performance flow control technologies.
Integration of wireless acoustic sensors and digital positioners on safety relief valves to monitor real-time leakage, pressure spikes, and seat integrity, enabling predictive maintenance before critical failures occur.
Adhering to strict fugitive emission standards (ISO 15848-1). Our bellows-sealed pressure relief valves prevent hazardous gas leaks, supporting Turkey's net-zero carbon goals and green industrial transition.
Utilizing high-grade materials such as Duplex Stainless Steel, Super Duplex, Hastelloy, and Monel to combat aggressive media in chemical processing plants and offshore installations.
