JIS 5K Cast Bronze 2 - way Ball Valve
Our JIS 5K cast bronze 2-way ball valve is engineered to Japanese Industrial Standards with a robust cast bronze body and full-port design, featuring a precision-machined bronze ball that provides bubble-tight sealing and minimal flow resistance with just a 90-degree rotation for quick on-off control. Built with cast bronze construction for enhanced strength and corrosion resistance, this valve delivers smooth operation, low operating torque and long service life, making it ideal for seawater and corrosive fluid applications requiring reliable shut-off performance.
Overview
Application: Widely used on ships, offshore platforms, coastal facilities and desalination plants for on-off control of seawater, freshwater, fuel oil and mildly corrosive fluids in low-pressure pipeline systems where excellent corrosion resistance and quick operation are essential. Also commonly specified in shipbuilding projects, chemical processing, HVAC systems and Japanese-standard marine engineering projects throughout Southeast Asia, particularly for applications requiring frequent operation, tight sealing and minimal pressure drop in corrosive environments.
