Check valve with plastic closing element,1 1/2" F-F
The non-return valve with a plastic closing element is a reliable component for domestic water installations, protecting the system against unwanted backflow. Designed for standard 1 1/2" connections, it fits common pipe layouts and supports stable operation of household water supply.
The durable CW617N brass body resists corrosion in contact with water, extending the service life of the valve. A nominal pressure of 10 bar suits typical residential water systems, while the compact length of around 68–73 mm helps when space behind the installation is limited. The internal design focuses on secure one-way flow rather than full bore, which supports effective backflow prevention.
The closing element made of robust ABS works smoothly with water media and maintains tightness over time. Nickel-free internal surfaces benefit users sensitive to nickel and align with modern requirements for drinking water fittings. The nut-to-nut connection simplifies assembly and disassembly during installation or maintenance.
This non-return valve is a practical choice for installers and homeowners looking for a solid backflow prevention valve in brass, combining durability, safe materials and convenient mounting in one compact product.
