Slant check valve – reliable protection for your installation

This DN20 slant valve, type 1603, with a 3/4 inch thread, is a key element in any water installation requiring protection against backflow and contamination. Made of CW617N brass, it is characterized by high corrosion resistance and ensures long-lasting, trouble-free operation. It is a shut-off device designed to ensure the safety and hygiene of drinking water.

Design and functionality

The valve combines shut-off and non-return functions, effectively blocking flow in the unwanted direction. Equipped with a non-rising stem, it allows for convenient operation even in hard-to-reach places – the knob remains stationary regardless of the degree of opening or closing of the valve. Additionally, it has a drain hole and two inspection holes, which facilitate maintenance and monitoring of the technical condition. Water flow is fully equal to the nominal diameter, minimizing pressure loss. Pressure class PN 16 guarantees safe operation under standard installation conditions.
