For modern engineering projects, procurement executives searching for a cheap piping gate manufacturer face the complex challenge of balancing upfront CapEx with long-term operational integrity. In industrial fluid networks, choosing sub-standard components can lead to costly valve failure, micro-leakages, and catastrophic pressure drops.
As a leading supplier based in Yuhuan, China's valve capital, we bridge this gap. Our state-of-the-art forging processes and smart material allocations allow us to supply high-durability brass gates and valve fittings that optimize cost structures without sacrificing mechanical resilience, complying with strict international regulations.
Our Legacy of Manufacturing Innovation Since 1996
Founded in 1996 in Yuhuan, Zhejiang—celebrated globally as the "China Valve Capital"—Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) has evolved into an industry-leading plumbing valve enterprise. We unify product design, advanced R&D, structural testing, and high-volume sales under one roof.
Our specialized product catalog is divided into three core categories: brass valves, pipe fittings, and HVAC distribution components. Engineered primarily for the medium and high-end markets, our products highlight the advantages of environmental sustainability and robust service life, making us a preferred choice across North America, Europe, and Asia.
Under our premium brand, Cokaren, and its foundational brand promise "keep flowing, keep warming," we design refined, long-lasting hydronic accessories that deliver safety and comfort to homes and industries worldwide.
Human-Centric Management Combined with Strict Manufacturing Compliance
Our company culture is built upon four pillars: Struggle, Enterprising, Pragmatic, and Innovative. Guided by our core tenet of "Customer First, Quality Based," we align business growth with our employees' development, cultivating a dedicated workforce that maintains the highest levels of workmanship.
Our quality policy, "Fine work, no leakage," is enforced across every production cell. From initial forging and sand-blasting to precision thread cutting and multi-stage testing, our automated workflows minimize human error, ensuring every gate valve and fitting leaves our facility with high performance certifications.
Eco-Friendly Manufacturing Backed by Verified Certifications
To support global supply chains, we maintain rigorous factory audits and hold multiple international safety and environmental certifications:
Our focus on lead-free and low-lead brass compositions meets European and North American environmental directives (such as RoHS and NSF/ANSI compliance), positioning us as a reliable partner for green initiatives.

Technical SpecsProviding information depth on how modernized valve design supports green building mandates.
Modern commercial infrastructure demands Dezincification Resistant (DZR) brass alloys. As a forward-thinking piping gate company, we incorporate optimized trace elements like arsenic to prevent selective zinc leaching, maintaining structural integrity when exposed to aggressive hot-water cycles.
Hydronic space heating is shifting toward smart balancing. Integrating mechanical thermal actuators with centralized room thermostats allows municipal district heating nodes to match user demands in real time. Our product designs reflect this, offering smart thermostats engineered to interface with brass manifolds.
Our "Fine work, no leakage" policy directly supports ESG goals. Even minor liquid loss in high-pressure networks leads to significant power waste in circulation pumps. Precision CNC threading (BSP/NPT) ensures robust, tight connections that limit carbon footprint and water waste.
Technical guidance and sourcing support for international plumbing components buyers.
We leverage our 45,000+ sqm factory layout in Yuhuan—China's valve capital. By using automated forging presses, centralized raw material sourcing, and specialized multi-axis CNC machine tools, we minimize material scrap and optimize output speed, passing the savings directly to our buyers without compromising mechanical tolerances.
We work with European standard CW617N, CW614N, and lead-free alloys like HPb59-1 or DZR brass depending on target market regulations. Every batch of raw brass is validated using optical emission spectrometers before thermal forging begins.
Generally, first-run OEM orders take 30 to 45 days. This includes drawing approval, customized forging mold development, CNC sample verification, mass production, and 100% pneumatic/hydraulic leak testing. Recurring orders are shipped faster, utilizing our pre-planned stock-casting program.
Yes. Our brass manifolds and temperature-controlled water dividers are CE certified. They are built to withstand working pressures up to PN10/PN16 and continuous high-temperature exposures, making them fully compliant with European HVAC requirements.
Following our "Fine work, no leakage" quality framework, we subject all brass valves to 100% pneumatic testing under water. Additionally, high-stress components undergo cyclic pressure fatigue testing and chemical composition validation to prevent Dezincification in hard-water zones.
Yes. With our selection of over 80 special machine tools and high-precision CNC stations, we manufacture NPT threads for North America, BSPP/BSPT for Europe and Asia, and custom compression inlets for PE-PEX composite pipes.

With drinking water safety regulations tightening worldwide, we have adopted advanced smelting procedures to decrease lead content in brass. Our manufacturing plant utilizes low-lead (≤0.25% Pb) and bismuth-doped lead-free brass formulations to meet strict environmental and public health standards.
These modifications enhance corrosion resistance, prevent zinc leaching, and protect domestic plumbing networks from lead contamination, qualifying our components for use in green building projects.
Many low-cost producers resort to sand casting, which frequently results in micro-porosities, casting defects, and structurally weak walls. Our products are manufactured using thermal forging processes:
