Invena stop valve ZA-01-015, cast iron straight-through 1/2"

Invena ZA-01-015 is a cast iron straight-through stop valve with a 1/2" connection designed for basic flow control in plumbing systems. Its straight-through geometry and quarter-turn operation provide a straightforward on/off function for isolating sections of piping during maintenance or repairs. The cast iron body delivers mechanical strength and stability suitable for residential and light commercial water installations where standard 1/2" fittings are used.

Advantages

The cast iron construction ensures durability and resistance to mechanical wear in typical water distribution environments. The straight-through design minimises flow resistance when open and makes the valve easy to fit in line with existing 1/2" piping. Simple on/off operation provides reliable isolation for routine maintenance and quick shut-off in case of leaks. The valve's compact form factor allows installation in confined spaces and standard connections simplify replacement and compatibility with common plumbing fittings.

Suitable for

• Isolation of domestic cold and hot water lines
• Maintenance shut-off in residential plumbing systems
• Light commercial water installations with standard 1/2" fittings
• Replacement of worn or leaking inline stop valves

Key specifications

• Body material: cast iron
• Connection type: straight-through, 1/2" threaded connection
• Function: manual on/off stop valve
• Orientation: inline straight-through design
• Typical applications: potable water and general water distribution (non-specific to compressed gases or hazardous fluids)

How to use

Install the valve inline with 1/2" threaded piping, ensuring sealing with appropriate thread tape or sealant as required by local plumbing practice. Use the handle to turn the valve between open and closed positions; the design provides a simple manual shut-off. Before installation, verify the valve orientation and system pressure compatibility. When closing the valve for maintenance, relieve downstream pressure and drain the line if necessary to avoid water discharge.

Usage recommendations

Use this stop valve for standard water distribution systems and avoid exposure to aggressive chemicals or media outside typical potable water parameters. Periodically inspect the valve body and connections for corrosion or leaks, and exercise the valve occasionally to prevent sticking. For systems with elevated pressures or specialized fluids, consult technical guidance to confirm material compatibility and suitability.
