Angle shut-off valve GEBO DV25 PN16 (DN25) for water installations

Angle shut-off valve GEBO DV25 PN16 (DN25) for water installations is a DN25 (1") angled stop valve designed for control and isolation of water flow in plumbing and heating systems. Built for nominal pressure PN16, this valve provides a compact solution for angular connections where shut-off, service isolation and simple flow control are required. The body and mechanism are designed for use in residential and light commercial water installations and integrate with standard DN25 pipework.

Advantages

The angle configuration allows installation where space is limited or where a change of flow direction is necessary. Rated to PN16, the valve is suitable for typical cold and hot water distribution and heating circuits within its pressure class. Its shut-off design enables straightforward maintenance and replacement of downstream components without draining large sections of the system. The construction focuses on reliability, easy operation and a compact footprint for tight installation points.

Suitable for

• Residential water supply and heating systems
• Light commercial plumbing and heating installations
• Service isolation of radiators, boilers and branch lines
• Retrofit or new-build installations with DN25 piping

Key specifications

• Nominal diameter: DN25 (approx. 1")
• Pressure rating: PN16 (suitable for systems up to 16 bar)
• Connection type: angled/90° orientation for line change and compact mounting
• Medium: water (cold and hot potable water, heating circuits within PN16)
• Typical application temperature range: compatible with standard domestic hot water and heating temperatures (within PN16 limits)

How to use

Install the angle shut-off valve in-line with DN25 piping, matching the valve orientation to the required change of flow direction. Use appropriate thread sealing or jointing method compatible with the pipe system being used and tighten to recommended torque for DN25 fittings. Operate the valve handle to open or close the flow as needed for system operation or maintenance. Before servicing downstream equipment, fully close the valve and verify isolation; depressurize and drain the local section if necessary following applicable safety practices.

Usage recommendations

Use the valve within the PN16 pressure class and within normal domestic or light commercial temperature ranges. For potable water applications, ensure compatibility of sealing materials with drinking water standards if required. Periodically operate the valve to prevent seizing in long-term installations and inspect joints for tightness after initial commissioning and during routine maintenance.
