KRK-RH Rectangular Flap Valve

Rectangular flap valve for installation on a flat wall.

The KWT KRK-RH Rectangular Flap Valve prevents unwanted backflow of water in pipelines and waterways. Thanks to its robust construction, reliable operation, and watertight sealing, the valve provides effective protection against flooding and reverse flow.

The KRK-RH is designed for surface mounting on flat walls and offers a durable, low-maintenance solution for water management, drainage, and hydraulic engineering applications.

 

Construction Rectangular design
Control Prevents backflow
Quality High operational reliability
Maintenance Low-maintenance operation

The KWT KRK-RH HDPE Flap Valve is used to prevent unwanted backflow in pipelines, outfalls, pumping stations, sewer systems, and hydraulic structures. The valve opens automatically during discharge and closes immediately when reverse flow occurs.

Thanks to its lightweight, corrosion-resistant HDPE construction, the KRK-RH is ideally suited for applications in water management, infrastructure, industry, and wastewater treatment.
