Nickel-plated ball valve with aluminum butterfly throttle (MAl) (N-N version) ONYX 3/4 inch 1453400

Ball valve with nickel-plated ONYX with a throttle and aluminum butterfly is a reliable solution for water installations, designed for both domestic and professional applications. Made of brass (CuZn40Pb2 – CW617N) ensures durability and corrosion resistance. Nickel plating additionally protects the valve against external factors.

Construction and application

This valve, with a nominal diameter of 3/4 inch (DN20), has internal BSPP-G (ISO 228-1) threaded connections, which facilitates installation in existing systems. Version N-N means that both ends of the valve have an internal thread. The throttle with an aluminum butterfly allows for precise flow control, which is particularly useful in systems requiring controlled pressure. Pressure class PN 40 guarantees safe operation even in installations with increased working pressure – up to 40 bar.

The valve finds application in:

• water supply installations in residential buildings,
• heating systems (depending on the specifications of the working fluid),
• industrial installations,
• irrigation systems.
