Request Spec SheetUnder the ambitious Saudi Vision 2030 framework, the Kingdom of Saudi Arabia is undergoing unprecedented civil and industrial transformation. Mega-developments like NEOM, Qiddiya, Red Sea Global, and the rapid expansion of metropolitan Riyadh demand ultra-reliable infrastructure components. Fluid control systems, particularly brass gate valves, stop valves, and manifolds, form the quiet backbone of this massive structural boom.
The geographical conditions of Saudi Arabia present extreme challenges for standard mechanical equipment. Temperatures routinely rise past 50°C in summer months, causing significant thermal expansion. Groundwater extraction and desalination networks involve highly mineralized, high-salinity water, causing aggressive galvanic corrosion in sub-standard alloy valves. Choosing industrial-grade brass valves designed with dezincification-resistant (DZR) materials is vital to ensuring low-maintenance municipal operations and avoiding catastrophic downtime.
As water security is declared a national priority, municipal planning agencies demand flow equipment that strictly eliminates leakages. Standardized certifications (ISO 9001, ISO 14001, OHSAS) are no longer optional—they are prerequisite credentials for suppliers wishing to integrate with national procurement grids like Aramco, SABIC, or the National Water Company (NWC).
Pioneering precision fluid control products since 1996, serving global markets under strict quality guidelines.
Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) was established in 1996 in the world-renowned "Valve Capital of China" — Yuhuan, Zhejiang Province. Over nearly three decades of targeted focus, the enterprise has grown to become a comprehensive manufacturer specializing in the research, design, production, and exporting of mid-to-high-grade brass valves, hose fittings, and HVAC distribution components.
Our infrastructure covers a vast factory area of 45,000 square meters, with a total usable production footprint reaching 80,000 square meters. Guided by an experienced engineering staff, we operate over 600 sets of advanced manufacturing and inspection systems. This includes 80 units of dedicated high-precision CNC machine tools. Our brand, Cokaren, operates under the core philosophy: "keep flowing, keep warming", exporting high-performance water systems to over 20 countries globally.
How we customize stop valves and manifolds to survive and excel in the Middle East climate.
For coastal Saudi zones like Dammam and Jeddah, groundwater possesses heavy mineral profiles. Standard brass leaks zinc into the medium, leading to structural failures. Yongda utilizes premium DZR brass formulations, keeping pipeline systems strong for decades.
With HVAC operations working continuously to offset intense heat, our automatic air vents, manifolds, and balance valves ensure continuous air removal. This stabilizes flow rates, maximizes cooling efficiency, and reduces utility electrical consumption.
Atmospheric sand in the Gulf region inevitably infiltrates municipal plumbing. Our integrated strainers and Y-pattern filters intercept 98% of line particulate matter, shielding vulnerable stop valve seals from abrasion-induced wear.
A unified lineup of premium, nickel-plated control mechanisms engineered for seamless integration into structural heating, cooling, and water delivery manifolds.
The primary barrier in commercial water sanitation lines, certified to catch 98% of sand and rust scale within the piping.
Features a heavy spherical brass spool designed to securely govern the temperature-critical cold and hot water intakes.
Engineered to constantly evacuate air pockets, safeguarding water heater pumps and preventing local dry-firing issues.
Integrates hot and cold bypass loops to stabilize pipeline temperatures, protecting downstream system seals.
Centralized digital hub designed to sync with automated brass manifolds to dynamically adjust zones.
A dual-purpose valve combining high-efficiency filtration, air venting, and local temperature gauges in one module.
Yuhuan represents the world's most concentrated brass valve manufacturing cluster, supplying over 50% of the world's brass plumbing devices. By maintaining our principal factory within this dense ecosystem, Yongda leverages complete upstream and downstream integration. From local high-precision brass extrusion plants to localized mold makers and chemical testing labs, our raw material sourcing takes hours rather than weeks.
This structural proximity translates directly into lead-time savings for Saudi buyers. Whether a project in NEOM or Dammam requires swift changes to thread specifications (BSP, NPT) or custom branding, our tooling workflow executes configurations in half the time of Western producers. Additionally, our automated forging line reduces waste, maintaining cost efficiency while keeping our quality policy absolute: "Fine work, no leakage."
Our modern quality department conducts 100% pneumatic sealing tests on every production run, ensuring zero out-of-box defects before dispatch. Operating in accordance with ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 guidelines guarantees that our manufacturing output aligns with strict global compliance protocols.

Request Spec SheetHow modern supply systems are changing, and what professional procurement officers expect from reliable partners.
Global procurement teams, especially those managing projects for Saudi Aramco or municipal utility groups, require transparent verification documents. The risk of using unregulated alloy compounds includes lead leaching or early structural failure. Our laboratory supplies complete metallurgical test sheets (Spectrographic Alloy Verification) with every bulk shipment to confirm zinc, lead, and copper contents adhere strictly to international sanitization criteria.
Modern commercial properties are moving away from entirely manual plumbing components. By pairing traditional stop valves with electric actuators or mixing shunts like our Y5020 and Y9031, builders achieve automated zoning. Automated valves regulate flow based on real-time temperature fluctuations, ensuring maximum cooling efficiency in arid conditions while cutting pipeline wear.
For large construction sites in Saudi Arabia, shipping delays can cause costly project holdups. Our factory is located near the Ningbo and Shanghai shipping ports, ensuring quick transit routing. We offer tailored packaging solutions, such as high-density moisture barrier packaging, to protect internal seals from dry, salt-laden sea air during maritime shipping across the Indian Ocean to Jeddah or Dammam port terminals.
Expert engineering answers for procurement managers and mechanical planners in the Gulf.
For coastal areas like Jeddah and Dammam, we recommend using CW602N (Dezincification Resistant - DZR) or low-lead C37700 brass. Standard brass alloys can experience zinc leaching when exposed to mineralized or brackish water, causing mechanical weak points. DZR brass ensures long-term structural integrity and prevents pipeline leakages.
Our quality control policy is "Fine work, no leakage." Every valve undergoes 100% pneumatic pressure testing at 0.6 MPa to 1.6 MPa (depending on the valve class) before packaging. We also conduct random destructive hydrostatic pressure tests and dimensional inspections using advanced optical measuring machines to verify thread alignment.
High ambient heat causes significant expansion in polymer seats. We utilize pure PTFE or high-grade EPDM for our internal seal structures, which are rated to function continuously at temperatures up to 120°C without deformation or chemical degradation. This is essential for both municipal water lines and commercial HVAC cooling loops.
For standard brass fittings and stock valve sizes, production is completed within 30-35 days from deposit confirmation. Custom OEM/ODM requests involving specialized thread configurations or unique body designs require approximately 45 days, which includes mold customization and initial casting sample verification.
