Stormwater shut-off valve PP-HT dn50 version B with rosette, for internal drainage systems, white color. ZB50-B BIAŁA

Internal drainage storm valve – reliable protection against flooding

The PP-HT dn50 storm valve in version B with a rosette is a key element protecting the drainage installation in your home. Designed for wall mounting, it acts as an effective barrier against sewage backflow, protecting rooms from the unpleasant consequences of flooding. An aesthetic masking rosette ensures discreet installation, and a solid construction guarantees long-lasting and trouble-free operation.

Construction and application

The valve in version B is mounted directly to the spigot of the fitting placed in the wall. The rosette allows stable mounting to the wall with two screws, eliminating the risk of accidental disconnection under pressure in the drainage system. This solution is ideal for connecting siphons (e.g., washbasin siphons) using a special connector with a nut. This makes the system tight and resistant to unwanted odors and sewage backflow.

Durability and safety – key product features

The valve made of high-quality PP-HT plastic is characterized by exceptional durability and resistance to high temperatures (up to 95°C). All metal elements are made of stainless steel, which ensures corrosion resistance and longevity. The valve design is designed to provide 100% unobstructed flow of sewage, eliminating the risk of blockages and slowing down drainage. In addition, the chrome-nickel coating of the flap effectively protects against rodents, protecting both the flap itself and the seal from damage. Above-standard resistance to internal pressure (up to 1.0 bar) guarantees safety and peace of mind. The lack of obstacles and steps in the flow further increases the efficiency of the device.
