Angle check valve SCHLOSSER DN15 GZ 1/2" x GW 1/2" model 601300002

SCHLOSSER angle check valve DN15 GZ 1/2" x GW 1/2" model 601300002 is a compact non-return valve designed to allow flow in one direction and prevent backflow in piping systems. Its angled body and DN15 thread fittings make it suitable for installations where space is limited and where standard 1/2" connections are used. The valve is intended for use in water supply lines, heating circuits and similar domestic or light commercial plumbing systems that require reliable prevention of reverse flow.

Advantages

The angled design facilitates installation in confined spaces and at pipe junctions where a straight valve would be impractical. Threaded GZ 1/2" and GW 1/2" connections provide compatibility with common 1/2" plumbing fittings, enabling straightforward integration into existing systems. The non-return function protects pumps, boilers and other equipment from reverse flow and potential damage. The compact DN15 size offers a balance of flow capacity and space efficiency for typical residential and light commercial applications.

Suitable for

• Domestic cold and hot water supply lines
• Heating circuit return lines to prevent backflow
• Connections to pumps and boilers where reverse flow must be avoided
• Tight or confined installations requiring angled fittings

Key specifications

• Connection type: male to female 1/2" threaded connections
• Nominal diameter: DN15 (approximately 1/2" flow size)
• Function: angle non-return (check) valve for one-way flow
• Typical application media: potable water and heating system water
• Design form: angled body to facilitate installation in confined spaces

How to use

Install the valve in the flow direction indicated on the body, ensuring the male (GZ) and female (GW) 1/2" threads are matched to the corresponding pipe fittings. Use appropriate thread sealant or tape suitable for potable water and heating systems to ensure a leak-free joint. Tighten connections with suitable wrenches without over-torquing to avoid damage to threads or valve body. Verify correct orientation by confirming that flow through the valve is allowed in the intended direction and blocked in reverse.

Usage recommendations

Prior to installation, flush the piping to remove debris that could impair the valve seat. Regular visual inspections and periodic system maintenance are recommended to ensure continued one-way operation; replace the valve if leakage or mechanical wear is observed. Use within the pressure and temperature limits of the surrounding system and follow local plumbing codes for installation.
