## Long description

INVENA ZK-32-F20 DN-20 (20 mm) is a water shut-off valve with an integrated mesh filter, designed for domestic and light commercial plumbing systems. The compact inline unit combines shut-off control and particle screening to protect downstream fixtures, appliances and pipework. It fits standard 20 mm connections and provides a simple way to isolate sections of a water supply while trapping sediment and larger debris before they enter taps, heaters or pumps.
Advantages
This INVENA valve integrates a reliable quarter-turn shut-off mechanism with a maintenance-accessible filter screen, reducing the need for separate fittings. The metal body and serviceable filter offer durability and ease of cleaning, helping to maintain water flow and prevent clogging of appliances. Its 20 mm size ensures compatibility with common domestic copper and plastic pipework and enables straightforward replacement or new installation.
