Sewer valve PP-HT dn50 version A, sanitary for internal drainage, ash color ZB50-A POPIEL

Protection against flooding and more – Karmat check valve

The PP-HT dn50 check valve, version A, is a reliable solution for protecting sewer systems in residential and commercial buildings. Designed for installation in horizontal sections of drainpipes with a diameter of 50 mm, it effectively protects against the effects of sewage backflow, minimizing the risk of flooding. Its construction allows securing several devices simultaneously connected to the same installation, making it a practical choice for both installers and end-users.

Construction and application – solidity and functionality

The valve is designed for easy installation and long-term operation. Version A is particularly recommended in situations where access to the installation is difficult, e.g. with bathtub or shower tray traps. Made of high-quality PP-HT material, it is resistant to temperatures up to 95°C, which guarantees its durability even when draining hot wastewater. All metal elements are made of stainless steel, ensuring corrosion resistance and long device life.

Key features and benefits

• Full flow: The valve design has no obstacles or steps, ensuring 100% undisturbed wastewater flow – no hydraulic restrictions guarantee installation efficiency.
• Rodent protection: The chrome-nickel plated flap protects not only the flap itself but also the seal against damage caused by rodents and prevents it from slipping during wastewater flow.
• Pressure resistance: The valve is characterized by above-standard resistance to internal pressure up to 1.0 bar – this ensures stable operation even under conditions of increased pressure in the installation.
• Durable materials: The use of the highest quality PP-HT material and stainless steel guarantees long-lasting and durable operation of the device.
• Easy installation: The valve is designed for horizontal mounting, making it easy to install in standard sewer systems.
• Manual closing: Allows additional protection against unpleasant odors during prolonged non-use of the sewer system.

The Karmat check valve is an investment in the safety and comfort of using the building. Its solid construction and functionality make it a reliable element of every modern sewer installation.
