## Long description

INVENA ZK-50-015 DN-15 is an angled shut-off water valve with a union nut designed for installation on supply risers and connections to plumbing fixtures. The compact right-angle design allows connection where space is limited and provides isolation of water flow for maintenance, repair, or replacement of fixtures. The valve is compatible with common residential and light commercial plumbing systems and is intended for use on toilets, sinks, radiators and similar supply lines.
Advantages
The angled construction enables installation in confined spaces and reduces stress on piping by providing a smooth change in flow direction. A union nut simplifies connection to fixtures and streamlines replacement without disassembling adjacent pipework. The valve offers reliable shut-off function for isolation during repairs and routine maintenance, and its DN-15 size matches standard small-diameter supply lines used in household and light commercial applications.
Suitable for
Isolation of cold and hot water supply lines to toilets and bidets
Supply shut-off for sinks and washbasins
Connections to radiators and small heating appliances in light commercial spaces
Retrofit and new installations where space constraints require a right-angle valve
Key specifications
Connection type: angled shut-off with union nut
Nominal size: DN-15 (suitable for ½" supply lines)
Flow control: manual on/off isolation
Application: potable water supply and heating supply lines in residential and light commercial installations
Installation orientation: right-angle (90°) inline connection
How to use
Shut off the upstream main supply before installation. Mount the valve to the supply riser and tighten the union nut to the fixture connection according to recommended torque values for the thread type and pipe material. After installation, open the upstream supply slowly and check for leaks at the union nut and connections. Operate the valve handle to verify smooth on/off movement and confirm a full shut-off. Use the valve to isolate fixtures during maintenance or replacement by turning to the closed position.
Usage recommendations
For reliable operation, inspect connections periodically and retighten the union nut if minor leaks occur. Do not use the valve for permanent throttling; it is designed for on/off isolation. If used in systems with aggressive or hard water, consider appropriate water treatment and routine inspection to avoid buildup that could affect sealing performance.
