Nickel-plated full-bore ball valve with aluminum flow control butterfly (MAl) (W-W version) ONYX 1/2 inch 1452430

Full-bore nickel-plated ball valve – reliability and precision in every connection

The ONYX ball valve is an element of water supply, heating and solar installations, designed for reliable closing and opening of flow. Made of high-quality brass, it ensures durability and corrosion resistance, and nickel plating provides additional protection against external factors. The version with a throttle and aluminum butterfly (MAl) allows for precise flow control.

This valve is perfect for both cold and hot water installations, as well as water heating systems and solar installations using glycol/water solutions. Its construction allows operation in a wide temperature range – up to 180°C – and at a maximum pressure of 4.0 MPa (40 bar). This makes it a universal solution adapted to various needs.

Construction and characteristic features

The valve has connecting threads compliant with the BSPP-G (ISO 228-1) standard – both internal (connection 1) and external (connection 2) with a diameter of 1/2 inch. Made of CuZn40Pb2 (CW617N) brass, it guarantees high material quality and resistance to mechanical damage. The PN 40 pressure class confirms its resistance to high working pressure.

It is worth paying attention to several important design features:

• Full-bore: Ensures minimal pressure drop of the flowing medium, which translates into the efficiency of the installation.
• Throttle with aluminum butterfly: Enables smooth flow regulation, which is particularly important in systems requiring precise control.
• W-W version: Indicates a nut-to-nut connection, facilitating the assembly and disassembly of the valve in the installation.
• Self-sealing stem: Ensures smooth valve operation and minimizes the risk of jamming.
• Lock on the body: Allows securing the valve against unauthorized opening or closing.

The ONYX valve is not only functionality but also ease of installation and high tightness of connections – key aspects for professional installers and users who value trouble-free operation.
