Direct procurement channels for certified components manufactured with aerospace-grade calibration standards.
In modern industrial operations, pressure and flow rate control are transitioning away from static mechanical spring-loaded regulators toward dynamic, digitally integrated systems. Proportional Electronic Pressure Regulators represent the pinnacle of this revolution. These devices actively measure downstream media conditions via internal piezoelectric sensor arrays, processing these telemetry signals using PID algorithms to adjust solenoid-driven control valves within milliseconds. This closed-loop configuration ensures immediate correction of system pressure fluctuations, maintaining pressure consistency even under rapidly shifting downstream volumes.
As a global leader in fluidics, Yuhuan Yongda Fluid Control Co., Ltd. (and our refined brand Cokaren) has leveraged our twenty-eight years of metal formulation and manufacturing expertise to build advanced electronic fluid regulation hardware. From our core base in Yuhuan, the valve capital of China, we provide specialized design and production capacity that connects robust brass valve design with sophisticated electronic actuators. This ensures high structural durability alongside precise pneumatic and hydronic performance.
Unlike passive diaphragm-style valves, an electronic proportional pressure regulator accepts standard analog input signals (such as 0-10 VDC, 4-20 mA) or digital protocols (RS-485 Modbus, CANbus) to dynamically scale pneumatic and hydraulic pressures. This capability is critical for automation systems where exact calibration curves, zero-leakage configurations, and dynamic setpoints are required to maximize system efficiency.
Global industrial purchasing departments must reconcile technical criteria, supply chain reliability, and localized compliance standards. When procuring electronic pressure regulators and fluid control assemblies, supply chain managers look for vendors that offer proven production capabilities, clear material trace records, and established testing procedures.
Yuhuan Yongda meets these demands through a vertically integrated design and manufacturing system. Our 45,000+ square meter factory (with a total usable layout of 80,000 square meters) houses over 600 sets of advanced testing and production equipment, including 80+ specialized machine tools. This capacity guarantees that every unit, from our heavy brass manifolds to integrated electronic control valves, conforms to exact engineering specifications before shipment.
Founded in 1996, Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) is located in Yuhuan, Zhejiang, the premier valve capital of China. As a professional fluid engineering and manufacturing enterprise, we specialize in the custom design, prototyping, testing, and volume production of high-performance brass valves, custom fittings, and integrated HVAC distribution components.
By positioning our products in mid-to-high tiers and prioritizing clean metal alloys and zero-leakage designs, we have established long-term supply agreements in North America, Western Europe, and across more than 20 countries. Under our premium brand Cokaren, we carry forward our core promise of "keep flowing, keep warming", ensuring building water systems operate with exceptional stability and minimal thermal loss.
Modern hydronic systems require integrated balancing and filtration components to ensure system longevity. To address this, Yuhuan Yongda designs and manufactures comprehensive energy distribution setups that protect building pipes and maintain uniform heat delivery.
Our modular fluid networks feature intelligent control interfaces, mechanical safety margins, and durable brass housings designed to resist cavitation and dezincification. Below are the key system elements optimized for underfloor layouts:
First line of defense, capturing 98% of particulate impurities.
Spherical spool valve regulating boiler inlet and outlet flows.
Automatic gas-release valve preventing vapor locks in pumps.
High-precision thermostatic mixing valve protecting system lines.
Integrated system controller linking sensors to valve actuators.
Multi-parameter monitor with pressure gauges and temperature ports.
Multi-zone hydronic manifold that distributes fluid flow to control room temperatures.
Our manufacturing operations are guided by the tenet: "Customer first, Quality based" and a clear quality policy: "Fine work, no leakage".
By implementing clean alloy melting, high-speed forging, and pneumatic testing systems on our assembly lines, we ensure that every valve is rated for long-term service under hot and cold water cycles. This focus on reliability helps prevent leaks, protecting building interiors and structural foundations.
In addition to product quality, we focus on developing our technical capabilities, improving workplace conditions, and aligning the company's growth with the long-term well-being of our workforce.
The future of industrial fluid dynamics lies at the intersection of material science and electronic control systems. Yuhuan Yongda is actively developing technologies across three primary areas:
