The DN50 2' BSP Female Thread Inline Spring Valve Non One Way Valve 229 PSI is a robust inline check valve designed to prevent backflow in piping systems. Made from 304 stainless steel, it combines corrosion resistance with durable performance in demanding environments. With a DN50 (50 mm) size and a 2 inch BSP female thread connection, this valve is built for reliable inline installation. The valve features a spring loaded mechanism and a 229 psi maximum pressure rating, delivering dependable one way flow control for a range of applications. Key Benefits Prevents backflow to protect pumps, meters, and downstream equipment, reducing the risk of contamination and damage. Inline, compact design enables easy installation without complex fittings or additional components. Durable 304 stainless steel construction provides corrosion resistance and long service life in demanding piping systems. pressure rating (229 psi) supports reliable performance in a variety of fluid systems. Simple operation as a one way, non valve with a spring mechanism for quick response to flow changes. Key Attributes Functionality: Inline spring check valve, non, one way flow Compatibility: DN50 (50 mm) pipe size with 2' BSP female thread connection Material: 304 stainless steel Size: DN50 / 2' BSP female thread Connection Type: BSP female thread Flow Direction: Oneway flow in the direction of normal system operation Pressure Rating: 229 psi maximum Design: Inline valve with builtin spring for rapid closure Specifications Model: DN50 2' BSP Female Thread Inline Spring Valve Non One Way Valve Material: 304 Stainless Steel Connection: BSP Female Thread, DN50 / 2' Type: Inline Spring Check Valve (Non) Maximum Pressure: 229 psi Flow: OneWay Applications and Use Cases Pump discharge protection: Install in industrial pump discharge lines to prevent reverse flow after shutdown, safeguarding pumps and downstream equipment. Water supply lines: Use in building or irrigation supply lines to eliminate backflow and maintain consistent downstream flow. Process piping with stainless steel requirements: Suitable for use in stainless steel piping systems where backflow prevention and corrosion resistance are needed. Installation and Maintenance Tips Ensure compatible BSP female threads and clean mating surfaces before installation. Install in the correct flow direction as indicated on the valve to ensure proper oneway operation. Use appropriate thread sealing methods compatible with BSP threads and the conveyed fluid. Inspect periodically for signs of wear or leakage and if needed to maintain backflow protection.
