New York's commercial real estate and industrial spaces operate under some of the most complex architectural demands globally. From the massive district-wide high-pressure heating operations down to high-density multi-family skyscrapers in Manhattan and Brooklyn, water distribution and HVAC systems must withstand continuous thermal stress, chemical additives, and pressure fluctuations.
As a veteran designer and exporter of flow control solutions, we align our engineering designs with the stringent requirements of the local market. This includes building code guidelines from the NYC Department of Buildings (DOB), Lead-Free compliance regulations, and standard certification bodies such as ASTM, ASME, NSF/ANSI 61, and NSF/ANSI 372. Our specialized brass alloys, high-performance press fittings, and smart radiant heat mixing components are manufactured to maintain hydraulic integrity for decades.

View Technical SpecificationsFounded in the valve capital of China, Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) has grown into a world-class manufacturing hub providing engineered solutions for global distributors.
Yuhuan Yongda Fluid Control Co., Ltd. features an extensive production layout with a factory floor exceeding 45,000 square meters, translating to a total actual usable floor area of 80,000 square meters. The plant integrates over 600 sets of advanced manufacturing and testing devices, including more than 80 specialized multi-axis CNC machine tools, automated hot forging machines, and high-precision leakage test benches. This hardware allows us to implement a quality policy of "fine work, no leakage," assuring that every custom brass valve, fitting, or manifold meets international quality expectations.
Our products are engineered around safety, ecological balance, and longevity. The organization has successfully attained ISO9001:2015 Quality Management System Certification, ISO14001:2015 Environmental Management System Certification, and ISO45001:2018 Occupational Health and Safety Management System Certification.
High-rise housing structures throughout Manhattan and Brooklyn demand heavy-duty brass tubing adapters and OEM Sylphon Bellows to manage system thermal movement, expansion, and pressure drops, keeping the municipal water supply flowing reliably across dozens of stories without structural leakage.
Modern developments and luxury renovations utilize floor heating manifolds and water mixing shunt systems to deliver efficient radiant heat. Our smart thermostat controllers and localized brass distribution manifolds stabilize water flow to provide comfortable ambient indoor temperatures.
To safeguard central commercial boiler systems from extreme thermal spikes, New York engineering specs demand robust safety relief groups, check valves, and magnetic dirt separators. Our brass mixing valves and automatic air vents reduce system wear and overall energy loss.
Leveraging our advanced manufacturing facility based in Yuhuan, the premier cluster of China's plumbing valves and fluid control industry, we secure competitive pricing on raw brass materials (DZR, lead-free C46400, CW617N, and CW602N). By managing chemical metallurgy, hot forging, mechanical precision CNC tooling, and testing completely under one roof, we lower development costs while upholding tight dimensional tolerances for our clients.
We maintain streamlined logistics channels with main shipping lines to provide seamless shipping services directly to the Port of New York and New Jersey. From handling custom export clearance to arranging LCL or FCL shipments, we facilitate cost-effective transport, ensuring consistent inventory replenishment for HVAC distributors, pipe series wholesalers, and commercial mechanical contractors across the Tri-State area.

View Technical SpecificationsIn addition to our traditional OEM fluid control services, Yuhuan Yongda proudly presents Cokaren—our brand focused on design innovation and premium workmanship. Designed for contemporary municipal projects, Cokaren products feature polished aesthetics, improved structural performance, and ergonomic operation.
Under the core promise of "keep flowing, keep warming," Cokaren products balance aesthetic refinement with engineering integrity. We are implementing a comprehensive brand strategy focused on dynamic growth, continuous improvement, and the path to becoming a world-class reference name for water system controls.
In compliance with the Safe Drinking Water Act (SDWA) and the strict plumbing regulations of New York State, all potable water distribution components must adhere to the Lead-Free definition. This mandates that the wetted surface area of pipes, fittings, and valves contain less than 0.25% lead by weighted average. Our production line utilizes specialized low-lead brass alloys (such as C46400 and bismuth-modified brass), ensuring full compliance with NSF/ANSI 61 and NSF/ANSI 372 standards. This ensures municipal water quality safety from the service entry to the tap.
The New York City Department of Environmental Protection (DEP) and the Department of Buildings (DOB) establish rigorous guidelines regarding backflow prevention, water pressure management, and system safety. For instance, high-pressure building configurations require double check valve assemblies to protect municipal water lines from potential cross-contamination. Additionally, hydronic and radiant systems must employ dedicated expansion devices and mixing setups to prevent pipe strain caused by thermal variation. Our manufactured manifolds, check valves, and air vents are engineered to meet these strict NYC guidelines, reducing municipal compliance risk for plumbing contractors.
In the commercial piping sector, physical durability is a primary requirement. Fittings and adapters must conform to exact chemical and physical requirements defined by the American Society for Testing and Materials (ASTM) and the American Society of Mechanical Engineers (ASME). Our brass adapters are manufactured in accordance with ASTM B62 / B584 standards to ensure structural strength and dezincification resistance (DZR). Thread designs follow ASME B1.20.1 NPT specifications, guaranteeing secure, leak-free seals with standard local pipe structures.
Yes. All of our brass fittings and valves destined for potable water systems are manufactured using specialized Lead-Free copper alloys. These products comply with NSF/ANSI 61 and NSF/ANSI 372 standards, maintaining a weighted lead content of less than 0.25% to satisfy local New York State plumbing regulations.
In multi-story structures, high-temperature water supply pipes expand and contract during system start-up and shut-down. Our OEM Sylphon Bellows act as elastic joints, absorbing axial expansion and vibrations. This helps protect the piping network from structural fatigue, preventing joints from cracking and causing leaks.
We offer a variety of standard brass alloys depending on application requirements: C37710/CW617N for standard gas and non-potable water control, CW602N (Dezincification Resistant - DZR) for aggressive water chemistry, and C46400/Lead-Free brass for US potable water distribution.
True to our quality policy of "fine work, no leakage," every valve and manifold is subjected to pneumatic or hydrostatic pressure tests prior to packaging. We also perform material analysis via spectrometry to confirm alloy compliance, and dimensional audits to ensure thread compatibility.
Typical production lead time ranges from 30 to 45 days, depending on order size. Transit time via ocean shipping from Ningbo/Shanghai ports to the Port of New York and New Jersey averages 30 to 35 days, resulting in a total lead time of approximately 65 to 80 days from order placement to port delivery.
