Nickel-plated full-bore ball valve with throttle and steel lever (DSt) (W-W version) ONYX 1 inch 1454470

Nickel-plated ball valve – reliability and precision in every system

A full-bore ball valve with a throttle and steel lever, in a W-W version, is an essential element in water supply, heating and solar installations. Designed for shutting off and opening flow, it combines durability, ease of installation and high performance parameters. Made of brass CW617N, it provides corrosion resistance and long-term reliability.

Construction and application

This valve, with a nominal diameter of 1 inch (25), has external gas tapered (BSPP) threaded connections, which facilitates integration with existing installations. Its full-bore design minimizes flow resistance, and the presence of a throttle allows for precise flow rate control. It can be used in both cold and hot water installations, as well as in water heating and solar systems with glycol/water solution. It withstands pressure up to 4.0 MPa and temperature up to 180°C – this guarantees safety and efficiency even in demanding conditions.

Advantages for professionals and users

• Strength and durability: The body made of brass CW617N provides corrosion resistance and long valve life.
• Wide range of applications: Ideal for water supply, heating and solar installations.
• Precise regulation: The throttle allows for accurate control of the medium flow.
• Easy installation: BSPP threaded connections facilitate quick and trouble-free installation.
• High performance parameters: Withstands pressure up to 4.0 MPa and temperature up to 180°C.
• Self-cleaning stem: Ensures smooth valve operation and minimizes the risk of failure.
• Lock on the body: Additional protection against loosening of the valve during operation.
• Resistance to high temperatures: Possibility of use in water heating systems with high temperature.
• Pressure class PN 25: Guarantee of safety when used in systems with increased working pressure.

This valve is not just a pipe connecting element – it is an investment in the reliable operation of the entire heating or water supply system. Its solid construction and precise workmanship translate into peace of mind for the user and the efficiency of the installer's work.
