High-integrity mechanical fittings optimized for Azerbaijan's HVAC and plumbing installations
Azerbaijan's modern infrastructure sector, catalyzed by the rapid residential expansion in Baku, the Karabakh rehabilitation initiative, and major chemical processing networks in Sumqayit, is witnessing an unprecedented transition from rigid, corrosion-prone metallic lines to advanced multilayer composite pipes (PEX-AL-PEX / PE-RT-AL-PE-RT). These composite structures require high-integrity joints capable of sustaining substantial thermal fluctuations and mechanical stresses.
Compression fittings stand out as the premium option for these piping networks. In contrast to press fittings, which necessitate specialized hydraulic machinery, compression adapters provide an exceptionally reliable, high-torque joint utilizing a brass compression ring (olive) and nut. This design is highly critical for remote installation sites in Azerbaijan where electrical grid availability is limited.
Our multilayer compression fittings utilize dual high-grade ethylene propylene diene monomer (EPDM) O-rings. This ensures complete gas and fluid isolation, counteracting thermal expansion cycles common in Azerbaijan's continental climate.
Integrated PTFE rings prevent direct electrochemical contact between the pipe's internal aluminum core and the brass body, completely neutralizing galvanic corrosion risks.
Forged with lead-limited brass alloys compliant with European Drinking Water Standards, assuring safe potable water distribution from regional reservoirs to municipal networks.
Established in 1996 in Yuhuan, Zhejiang—widely recognized as the valve manufacturing capital of China—Yuhuan Yongda Fluid Control Co., Ltd. has developed into a leading designer and manufacturer of brass valves, multilayer fittings, and specialized HVAC components. Our manufacturing facility spans an expansive 45,000 square meters, with an operational footprint reaching over 80,000 square meters.
Our production environment is equipped with over 600 sets of advanced manufacturing and testing devices, including 80+ specialized CNC machining centers. This robust technical foundation allows us to produce high-precision brass components that consistently satisfy international quality requirements.
Through our premium brand Cokaren, we implement a customer-focused philosophy: "keep flowing, keep warming". Cokaren is dedicated to delivering highly refined, reliable fluid control accessories that optimize the safety and comfort of heating and plumbing installations worldwide.
Integrated solutions managing heat and water routing in modern residential complexes
Serves as the primary barrier in domestic water lines. It removes up to 98% of particulates, protecting downstream multilayer piping and brass fittings from abrasive sediment damage.
Engineered with a robust spherical spool, this valve provides reliable control over high-temperature water supply and return lines in boiler systems.
Continuously vents accumulated air pockets from domestic water heaters and heating lines, ensuring stable, noise-free system operation.
Balances and mixes hot and cold water inputs to provide a stabilized output temperature, protecting pipeline networks from thermal shock.
Monitors and adjusts zone temperatures by interfacing with manifolds and mixing valves, optimizing energy efficiency in residential layouts.
Distributes flow evenly across heating loops. Built with durable brass headers, it ensures balanced heat distribution in commercial radiant floor systems.
Our company operates in strict compliance with international manufacturing guidelines, maintaining ISO 9001:2015 (Quality Management), ISO 14001:2015 (Environmental Management), and ISO 45001:2018 (Occupational Health and Safety) certifications. This comprehensive management structure guarantees that every step of the fabrication process—from selecting brass raw material to automated CNC turning and pressure testing—is tightly controlled.
Our quality standard, "Fine work, no leakage," serves as the core principle of our testing protocols. Each fitting undergoes pneumatic tests under high-pressure conditions to ensure absolute sealing performance. The robust structural design of Cokaren brass components provides excellent pressure resistance (PN25/PN16) and a wide operational temperature range, making them suitable for demanding hot water and industrial fluid projects.
Engineering installations using high-grade brass compression fittings
Baku’s modern high-rise projects require reliable HVAC lines. Our multilayer compression adapters connect PEX-AL-PEX loops to central fan-coil systems, maintaining structural integrity under high pressure and thermal cycling.
Our corrosion-resistant, CW617N brass fittings are widely used in drinking water upgrades across Ganja and Sumqayit, preventing zinc leaching and ensuring safe potable water delivery.
Designed to withstand the humid, saline environment of the Caspian coast, our nickel-plated brass fittings offer superior resistance to ambient atmospheric corrosion.
