## Long description

The UN H/ZK-72-015 straight ball valve with a 1/2" connection is a normally closed (N/C) heavy type valve designed for manual on/off control of fluid flow. This compact quarter-turn valve features a butterfly lever for easy operation and a robust construction intended for residential and light industrial piping systems. It provides straightforward shutoff performance where a reliable, space-efficient ball valve is required.
Advantages
The heavy-type body and ball design ensure mechanical durability and resistance to wear in frequent on/off cycles. The butterfly lever offers quick quarter-turn operation and clear visual indication of the valve position. The straight configuration maintains a compact inline profile that simplifies installation in tight spaces. The normally closed arrangement gives predictable default behavior when the actuator is not engaged.
Suitable for
Domestic water supply shutoff and isolation
Heating and radiator circuits in residential buildings
Light industrial fluid lines requiring manual isolation
Plumbing repairs and retrofit work in confined installations
Key specifications
Connection size: 1/2" (straight inline)
Valve type: ball valve, quarter-turn
Operation: manual, butterfly lever handle
Default state: normally closed (N/C)
Design style: heavy type for enhanced durability
Mounting orientation: inline, suitable for compact pipe runs
How to use
Install the valve in-line with the pipework ensuring correct orientation and secure threaded or fitted connections according to piping standards. To open the valve, rotate the butterfly lever a quarter turn until the lever aligns with the pipe axis; to close, rotate the lever back to its perpendicular position. Verify there are no leaks after installation by pressurizing the system and observing joints and body seals. The valve is intended for manual operation and does not require external power sources.
Usage recommendations
Use the valve within the temperature and pressure limits appropriate for the materials in your system, and avoid using it with aggressive chemicals unless compatibility is confirmed. Periodically inspect for signs of wear or leakage, and operate the lever occasionally to prevent seizing in long-term static installations.
