## Long description

SCHLOSSER check valve DN15 straight with Eurocone connection, coupling 3/4G male to 1/2G male, is designed to allow unidirectional flow and prevent backflow in water supply systems. The valve body accommodates a DN15 pipe size and standard threaded connections, making it suitable for domestic and light commercial plumbing installations where a compact inline check valve is required.
Advantages
The straight check valve features a Eurocone connection and stepped male threads enabling compatibility between 3/4G and 1/2G fittings without additional adapters. Its compact inline design minimizes pressure drop while providing reliable backflow protection. Constructed for corrosion resistance and durability in typical potable water conditions, the valve requires minimal maintenance and offers straightforward installation due to its threaded connections.

Domestic water supply lines with DN15 piping

Key specifications
Pipe size: DN15 (nominal)
Connection type: Eurocone straight coupling
Threaded ends: 3/4G male to 1/2G male

How to use
Install the SCHLOSSER DN15 straight check valve in the supply line with the arrow or indicated flow direction matching the intended water flow. Ensure thread seals or appropriate sealing tape are applied to the male threads to prevent leaks. Tighten the connections using suitable tools without over-torquing to avoid damaging the threads or Eurocone interface. Verify that the valve closes properly by testing flow and checking for any reverse flow or leakage.
Usage recommendations
Inspect the valve periodically for scale, debris, or signs of corrosion, especially in hard water conditions. If installed in a system with suspended solids or high particulate content, consider upstream filtration to prolong valve life. Follow local plumbing codes and manufacturer installation guidance for orientation, pressure limits and maintenance intervals.
