Engineered brass and copper-alloy control elements highly compliant with municipal pressure matrices in Pakistan.
As Pakistan undergoes massive infrastructure modernization—spurred by urban expansions in Punjab and Sindh, and collaborative investments under the China-Pakistan Economic Corridor (CPEC)—the demand for high-reliability fluid control components has soared. Industrial sectors, municipal water agencies (such as WASA and KWSB), and modern HVAC project designers are demanding materials capable of handling challenging local conditions, including high chemical calcification and seasonal pressure volatility.
Local contractors are shifting away from low-cost, uncertified valves to high-performance brass fittings. Using substandard valves leads to rapid wear, mineral scaling, and costly system shutdowns. High-grade brass alloys, engineered with optimal copper and zinc proportions, provide critical corrosion resistance and mechanical integrity needed in Lahore's high-temperature summers and Karachi’s coastal humidity.
Yuhuan Yongda Fluid Control Co., Ltd. fills this gap by offering reliable solutions, supplying export-grade, ISO-certified brass ball valves directly from Yuhuan, China's valve capital, tailored to Pakistani project parameters.
Founded in 1996, we combine scale, engineering expertise, and stringent quality control systems to serve markets worldwide.
Our brand promise is "keep flowing, keep warming". Through our dedicated brand Cokaren, we are implementing strategies to serve as a highly dynamic, world-class enterprise, supplying refitted manifolds, high-purity brass ball valves, and comprehensive climate control units.

Expert insights on importing, installing, and specifying brass ball valves for engineering projects in Pakistan.
CW617N is a European standard alloy (CuZn40Pb2) that offers excellent forgeability and mechanical strength. In many Pakistani municipal networks, water contains high amounts of mineral salts and contaminants. Cheaper alloys with poor composition are prone to dezincification, leading to premature brittle failure and toxic lead leaching. Our CW617N valves guarantee reliable performance and safe drinking water.
We manufacture valves with ISO 228 (BSP) parallel threads, which match the standard plumbing threads used in Pakistan. Additionally, we provide custom NPT thread configurations for specialized industrial applications. We verify thread dimensions using calibrated ring and plug gauges during production.
Typically, bulk production takes 30 to 45 days depending on the customization and order volume. Sea freight transit from Ningbo or Shanghai port to Karachi takes approximately 18 to 22 days. This ensures a total turnaround of 6 to 9 weeks from order confirmation to arrival at your local port.
We perform 100% pneumatic testing on every valve. The valves are subjected to pressurized air under water to detect even minor bubble formations. This process ensures zero leakage at high pressures, preventing costly maintenance issues for end users in Pakistan.
