2 Inch SS Ball Valve DN50 Stainless Steel For Cooling Water & Irrigation Pipeline
ss ball valve 2 inch DN50 stainless steel full port design, threaded/flanged type, manual/pneumatic for industrial water, irrigation & food pipelines.
Description
The ss ball valve 2 inch (DN50) is a versatile medium‑bore shut‑off valve widely used in water supply/drainage, circulating cooling, irrigation, food & daily chemical processing, and low‑pressure oil & gas pipelines. It is available in three mainstream configurations: two‑piece threaded, three‑piece ANSI flanged, and sanitary clamp types.
The forged 304/316L stainless steel body, combined with a full‑port design, ensures extremely low fluid resistance. A 90° quick quarter‑turn operation provides full open/close functionality, delivering both high‑capacity flow and tight sealing. The valve is compatible with major global piping standards including BS, ANSI, and GB, making it suitable for factory cooling systems, municipal water networks, agricultural irrigation, pure water production, and small‑to‑medium chemical process lines.
All body components are manufactured via forging to eliminate casting defects such as porosity or sand inclusions that can lead to leakage. The pressure rating reaches 1000WOG (PN64). The ball is CNC mirror‑polished and paired with modified PTFE seats, achieving a zero‑leakage shut‑off per ANSI Class VI—withstanding hundreds of thousands of cycles without loss of seal integrity.
Three connection options are offered: 2″ NPT (American taper), 2″ BSP (British standard), and ANSI Class 150 flanged ends. The threaded versions require no welding—simply screw into the pipe for quick installation, ideal for retrofit projects. The three‑piece flanged design features a modular construction that allows seat replacement without dismantling the entire pipeline, significantly reducing plant downtime. The sanitary clamp variant has a crevice‑free interior compatible with CIP cleaning, suited for food and pharmaceutical applications.
The ss ball valve 2 inch can be fitted with manual extended handles, pneumatic actuators, or electric drives. Manual operation is cost‑effective for routine inspection lines, while automated cooling systems and pure water plants often adopt the pneumatic 2 inch ss ball valve to interface with PLC control systems for remote monitoring.
Material options include general‑purpose 304 stainless steel and corrosion‑resistant 316L. The 304 grade offers excellent cost‑performance for tap water, circulating cooling water, and compressed air services. The 316L variant resists chloride and mild acid attack, making it suitable for pure water, seawater irrigation, and mildly corrosive chemical streams. For highly saline coastal environments, an upgrade to 2205 duplex stainless steel is available.
Compared with brass ball valves of the same size, stainless steel does not leach heavy metals into the fluid. In contrast to gate or globe valves, the full‑port ball design eliminates throttling pressure drop, reducing pump energy consumption by 15–22%. All products are tested per API 598, with each unit undergoing hydrostatic and pneumatic leakage tests prior to shipment. Material test reports and CE certification are provided, and OEM branding (logo engraving) is available upon request.

Industrial cooling main lines handle high flow rates and operate continuously, where pressure loss directly impacts plant electricity costs. European cooling stations widely adopt 2‑inch full‑port stainless steel ball valves to optimize network performance. A case in point: the Budapest Central Cooling Station (47 Industrial Boulevard, Budapest, Hungary) undertook a cooling network upgrade.
The original DN50 globe valves caused severe throttling, forcing cooling pumps to run at high loads with elevated power consumption. Frequent valve‑trim erosion led to leakage and monthly shutdowns for repairs. After replacing all units with the ss ball valve 2 inch (three‑piece flanged design), the full‑port configuration virtually eliminated pressure loss, cutting pump energy use by 17%.
The three‑piece modular body allows seal replacement by simply dismantling the middle section—reducing single maintenance time from 4 hours down to 1 hour. The 316L stainless steel body withstood disinfectant corrosion in the circulating water, showing no signs of leakage or rust after 36 months of operation, resulting in substantially lower overall maintenance costs.
While brass ball valves are prone to corrosion and medium contamination, and globe valves impose high flow resistance and energy penalties, the ss ball valve 2 inch combines a standard bore, full‑port low pressure drop, and stainless steel durability—establishing itself as the standard shut‑off valve for DN50 industrial pipelines worldwide.
