## Long description

UN angle stop valve model ZC23 is a frost-resistant shut-off valve with a 1/2" inlet and 3/4" outlet supplied as a single unit. The valve is intended for isolating sections of water supply systems where protection against freezing is required. Its compact angled body facilitates installation in tight spaces such as under sinks, inside service cabinets or along exterior walls, and it is suitable for both residential and light commercial plumbing applications.
Advantages
The frost-resistant design reduces the risk of damage from low temperatures by preventing water retention in the valve body after shut-off. The angled configuration provides straightforward control of flow direction and easier access for manual operation in confined installations. Durable materials and a simple shut-off mechanism ensure reliable isolation of water lines during maintenance or winterization procedures.
Suitable for
 Isolating domestic cold and hot water lines in bathrooms and kitchens
 Plumbing installations in unheated or partially heated spaces
 Repair and replacement tasks where a compact, angled shut-off is needed
 Systems requiring winterization or freeze protection
Key specifications
 Valve type: angled stop/shut-off valve
 Inlet connection size: 1/2"
 Outlet connection size: 3/4"
 Supply format: single piece
 Frost-resistant construction for reduced freeze risk
 Typical installation orientation: angled (90°)
How to use
Install the valve in the water line at the desired isolation point, ensuring that inlet and outlet orientations match the piping layout. Use appropriate fittings and thread sealant or tape on the threaded connections as required by local plumbing practice. Operate the manual control to open or close the flow; after shutting off, verify downstream fixtures are isolated and drain any remaining water from the section if winter protection is required. Follow local codes and, if unsure, consult a qualified plumber for installation and pressure testing.
Usage recommendations
For reliable freeze protection, install the valve where it will not trap water in the body after shut-off and provide insulation or heat tracing for exposed sections of pipe. Regularly operate the valve during seasonal maintenance to confirm smooth function and check for leaks at connections.
