## Long description

Angle ball valve UN ZK-54-015-W 1/2" Heavy Type with Half-Screw and Butterfly Handle is a compact angled shut-off valve intended for use in plumbing and heating systems. It features a 90° turn ball mechanism for straightforward on/off control of water and compatible media. The valve's angled body and half-screw connection enable installation in confined spaces and at pipe junctions where a change of flow direction is required.
Advantages
The heavy-type construction provides increased durability and mechanical strength compared with standard valves, while the half-screw connection simplifies installation and ensures a stable connection to compatible fittings. The butterfly (wing) handle offers clear tactile feedback and quick manual operation. The angled design reduces the need for additional elbow fittings and helps maintain compact piping layouts.

How to use
Install the angle ball valve inline with the pipeline so the flow direction matches the valve orientation. Tighten the half-screw connection to appropriate torque using compatible tools and fittings to avoid leaks. Operate the valve by turning the butterfly handle a quarter turn (90°) to open or close the flow. Verify sealing after installation and perform a pressure test according to local plumbing standards.
Usage recommendations
For long service life, avoid exposing the valve to corrosive chemicals and ensure water is free of large abrasive particles. Periodically cycle the valve and inspect the seals for wear when used in heating systems. Follow local codes for installation and test the connection after assembly to confirm leak-free operation.
