## Summary description

Straight check valve SCHLOSSER DN15 with male G1/2" (GZ) to female G1/2" (GW) connections, model 601300004. Designed to allow unidirectional flow and prevent backflow in DN15 piping systems. Suitable for use in residential and light commercial water installations, heating circuits, and plumbing applications where compact inline backflow prevention is required.

## Long description

Straight check valve SCHLOSSER DN15 GZ 1/2" × GW 1/2" model 601300004 is a compact inline non-return valve designed for DN15 piping systems. It permits flow in one direction while preventing backflow, making it suitable for residential and light commercial water installations as well as heating circuits. The valve's straight-body design with male G1/2" to female G1/2" thread connections enables simple inline installation where space is limited and a reliable seal is required.
Advantages
This SCHLOSSER check valve offers reliable one-way flow control with a compact straight configuration that fits standard DN15 piping. The threaded male-to-female connection simplifies replacement and integration into existing plumbing runs without the need for additional adapters. The valve construction is designed for minimal pressure drop in normal operating conditions and to reduce the risk of backflow in potable water and heating applications.
Suitable for
 Residential water supply lines and plumbing fixtures
 Heating system circuits and boiler returns
 Compact inline installation where DN15 (1/2") connections are used
 Prevention of reverse flow in light commercial water systems
Key specifications
 Nominal size: DN15 (1/2")
 Connection type: straight, male G1/2" to female G1/2" threads
 Function: check (non-return) valve for unidirectional flow
 Typical application: water and heating circuits for residential and light commercial use
 Installation orientation: inline, straight pipe configuration
How to use
Select an appropriate location in the DN15 pipeline where prevention of backflow is required and ensure the flow direction matches the valve orientation. Shut off the system supply and drain the section of pipe before removal of any fittings. Fit the male G1/2" thread into the mating female thread and engage the female thread end on the opposite side, applying suitable thread sealant or tape where required by local plumbing practice. Tighten connections to achieve a leak-free joint without over-torquing. After installation, restore supply and check the valve for proper operation and absence of leaks under normal system pressure.
Usage recommendations
For long-term performance, install the valve in a location accessible for inspection and maintenance, avoid exposure to freezing conditions, and follow local plumbing codes for thread sealing and mounting. If used in heating systems, consider periodic checks during commissioning and seasonal start-ups to ensure the non-return function remains effective.
