In modern piping infrastructure and HVAC systems, preventing backflow while maintaining system pressure is crucial. The Disk Check Valve represents a pinnacle of compact, spring-assisted, unidirectional fluid control. Also known as a disc check valve or non-return valve, it features a disc that moves along the fluid flow axis. The integration of precision spring loading ensures fast closure response, minimizing hydraulic shocks, also known as water hammer.
For global EPC (Engineering, Procurement, and Construction) companies and HVAC system integrators, obtaining a CE Certified Disk Check Valve is not just a regulatory checkmark. It is a critical assurance that the valves meet the European Union's strict Pressure Equipment Directive (PED 2014/68/EU). CE marking guarantees that the mechanical design, material thickness, pressure boundaries, and sealing integrity have undergone strict testing.
Compared to traditional swing check valves, disk check valves offer significant benefits:
Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) was founded in 1996 and is located in the famous "China Valve Capital" – Yuhuan, Zhejiang. As a premier plumbing valve enterprise, we focus on engineering design, product development, production, and sales.
Our portfolio focuses on middle and high-grade products across three main categories: brass valves, fittings, and HVAC system accessories. Emphasizing environmental safety, Lead-Free brass formulation, and dezincification resistance (DZR), our products are highly favored by consumers and contractors in North America, Europe, and domestic markets.
To serve our customers, we introduced our premium brand Cokaren. With the brand promise "Keep Flowing, Keep Warming", Cokaren develops water system accessories that bring refined aesthetics, robust durability, and reliable heating to homes worldwide.
As global energy efficiency directives tighten, the design of check valves is shifting. Modern HVAC and industrial networks require minimal head loss to reduce system pumping power. Key industry trends include:
Industrial buyers and purchasing managers face challenging decisions in maintaining components for district heating systems, gas distributions, and manufacturing plants. Professional procurement processes must audit:
