Female - female, lever handles

This category includes EVOLUTION series internal lever ball caps designed for use in heating, plumbing and irrigation systems. These ball caps feature internal female threads (FF) and a full-flow design for minimal pressure loss. They are constructed from nickel-platted brass CW617N and certified for use in potable water applications. Available in sizes from 1/4" to 6/4" and pressure ratings from PN 16 to PN 50, they are suitable for a range of residential and commercial installations.

The double-sided extended lever allows for easy operation, even in tight spaces. The operating temperature range extends from -20°C to +120°C, making these valves suitable for both cold and hot water systems. These ball caps are ideal for use in heating circuits, domestic water supply lines and filtration systems where reliable shutoff is required.

How to choose
