Gv. internal - external, 6/4" FM

Product detailed description

This ball valve is commonly used in residential and commercial water supply systems, heating circuits, and industrial applications where reliable shut-off is required. It is ideal for use in central heating systems, domestic hot and cold water lines, and in irrigation or pump systems. The internal-external configuration allows for flexible installation in confined spaces, especially where pipe alignment is difficult. The extended thread ensures a stable connection even in awkward positions.

The PN 25 rating makes it suitable for high-pressure environments, while the temperature range from -20°C to +120°C ensures compatibility with both chilled and heated water systems. The nickel-plated brass body provides resistance to corrosion and ensures long-term durability in aggressive environments.

Technical parameters

Installation and connection

Install the valve between two threaded pipe ends, ensuring the internal thread aligns with one side and the external thread with the other. Use a suitable sealing compound or PTFE tape on the threads to prevent leaks. Verify that the lever is positioned for easy access after installation. A common mistake during installation is over-tightening the valve, which can damage the sealing surfaces. Always check the direction of flow indicated on the valve body to ensure correct orientation. Confirm the lever is in the fully open or closed position before securing the valve in place.

Compatibility and accessories

This valve is compatible with standard copper, steel, and plastic piping systems. For installation, ensure that the pipe ends are clean and undamaged. No additional accessories are required for basic installation, but sealing compounds or pipe thread sealants may be necessary depending on the system. Refer to the manufacturer’s technical documentation for specific compatibility with other IVAR components.

Technical background for designers

The ball valve operates using a rotating ball with a through-hole that allows or blocks fluid flow when turned. The nickel-plated brass body ensures resistance to corrosion and maintains structural integrity in fluctuating temperatures. The CW617N alloy is particularly suited to water systems due to its low lead content and compliance with potable water standards. The extended thread design enhances flexibility in installation and reduces the need for additional fittings. The PN 25 pressure rating ensures the valve can handle medium to high-pressure conditions without leakage or failure.

Service and operation

Regular visual inspection is recommended to ensure the valve remains leak-free and the lever moves freely. No scheduled maintenance is required under normal operating conditions. If the valve becomes stiff or unresponsive, disassemble it carefully and inspect the sealing surfaces and ball mechanism for wear or debris. Reassembly should be performed using clean components and appropriate sealing materials.
