Velan B04-7034B-02TS Butt Weld Piston Check Valve

The Velan B04-7034B-02TS is a 3/4-inch, Class 900 steel butt weld piston check valve (MPN: B04-7034B-02TS) that provides automatic backflow prevention in high-pressure piping. Its forged steel body with butt weld ends and a piston-style check mechanism delivers reliable non-return performance in demanding services—especially high-pressure steam lines, hydrocarbon processing, and chemical transfer systems. This valve is commonly used in power generation facilities, oil and gas operations, refineries, and chemical processing plants, and is widely chosen by maintenance teams, OEMs, and system integrators for equipment replacement, pipeline upgrades, preventive maintenance, and new installations.
