SHUANGLIN VALVE | CW617N Brass Lever Ball Valve, PN20, DN15–DN50

Some jobs call for a valve rated beyond standard residential pressure — process lines, compressed air systems, and industrial fluid handling that residential-grade fittings simply aren't built for. SHUANGLIN VALVE's CW617N lever ball valve is manufactured from forged CW617N brass and rated to PN20, giving it the material integrity and pressure headroom for more demanding applications while remaining a straightforward, general-purpose shut-off valve.

Forged Brass for Demanding Conditions

CW617N is a widely specified forged brass alloy known for its strength and machinability, commonly required in European and international valve standards for pressure-rated fittings. Manufacturing this valve from CW617N brass, rather than a lighter-duty alloy, gives it the structural integrity to handle PN30 working pressure reliably across repeated open/close cycles, and to perform consistently across a broader range of media — water, oil, and compressed air — rather than being limited to a single application type.

Straightforward, Reliable Operation

A standard red lever handle provides quarter-turn shut-off with a firm, single-hand grip, and the valve body is clearly stamped with its size and pressure rating for easy identification during installation or inspection. SHUANGLIN VALVE produces this valve across the DN15 to DN50 size range, with female threaded connections suited to a wide range of plumbing, HVAC, and industrial piping systems.

Frequently Asked Questions

What does the CW617N marking on the valve body mean? CW617N refers to the specific forged brass alloy used to manufacture the valve body, widely recognized in international valve standards for its strength and suitability in pressure-rated applications.

Is PN30 higher than what a typical residential valve needs? Yes, PN30 provides pressure headroom beyond typical residential plumbing requirements, making this valve suitable for both standard installations and higher-demand industrial or commercial applications.

Can this valve be used for compressed air as well as water? Yes, the CW617N brass construction and standard seat materials make this valve suitable for water, oil, and compressed air systems within its rated pressure and temperature range.
