Check valve with plastic closing element, 1 1/4", FF
The non-return valve with plastic closing elements, 1 1/4", nut–nut connection is a reliable component for domestic water installations. It protects the system against backflow and supports stable operation of pumps, heating circuits, and other hydraulic devices.
Designed for media such as water and mixtures with up to 50% glycol, the valve works safely at pressures up to 16 bar and a maximum temperature of 70°C. The DN 32 connection and G 1 1/4 thread fit common installation standards, so the product integrates easily into typical plumbing or heating lines.
The body made of CW617N brass in 4MS quality offers high resistance to corrosion, while the ABS closing element ensures light operation of the mechanism. The nickel-free design benefits users sensitive to contact with nickel. The nut–nut connection shortens installation time and supports convenient disassembly during service work.
This non-return valve is a solid choice for professional installers and demanding homeowners who expect durable materials, dependable backflow protection, and compatibility with modern water and heating systems.
