The DN50 2' BSP Female Thread Inline Spring Valve is a stainless steel check valve designed for inline installation. Constructed from 304 stainless steel, it provides durable, corrosion resistant performance for water and other non corrosive fluids. The spring loaded mechanism ensures reliable non and one way flow, closing promptly when flow reverses. With a BSP female thread and a nominal size of DN50 (2 inches), this valve offers straightforward integration into compatible piping systems. It is rated to 229 PSI, making it suitable for light to medium duty applications where backflow prevention is required. Key attributes Size and connections: DN50 (2 inch) inline valve with BSP female thread Material: 304 stainless steel Function: inline spring check valve, non, one way flow Pressure rating: 229 PSI Flow direction: install in the flow direction (inlet to outlet) as indicated by the valve Compatibility: suitable for fluids compatible with 304 stainless steel; appropriate for water and other non corrosive fluids Installation: designed for straightforward inline installation Applications: ideal for protecting upstream sources and downstream equipment in water supply lines, irrigation systems, pump discharge lines, and filtration or processing lines Use cases In a residential or commercial water supply line to prevent backflow when a pump or valve is shut off In irrigation or sprinkler systems to stop dirty or returning water from flowing back into the main line In filtration or processing lines handling water, oils, or other non corrosive fluids where maintaining unidirectional flow is important Notes Ensure correct orientation and flow direction during installation Suitable for fluids compatible with 304 stainless steel; avoid exposure to aggressive chemicals unless compatibility is confirmed
