Gv. internal - internal, 1" FF

Product detailed description

Internal-to-internal ball valves are essential components in water supply, heating, and sanitation systems. They are commonly used in residential and commercial buildings to control the flow of water in pipelines. Installers and technicians frequently encounter these valves during system design, maintenance, and repair tasks. The valve’s internal threads allow for direct connection to pipe fittings, reducing the need for additional adapters and ensuring a secure seal.

This valve is particularly suited for applications where a compact, durable solution is required. Its extended thread design ensures ease of installation and alignment in tight spaces. The nickel-plated brass body provides resistance to corrosion and ensures long-term performance in environments where exposure to moisture is common. The operating temperature range allows the valve to function effectively in both cold and hot water systems.

Technical parameters

Material	Nickel-plated brass CW617N ATEST for potable water
Operating temperature	-20 °C
Nominal pressure	PN 30
Weight	0.466 kg
Code	80001100
Brand	IVAR

The valve operates under a nominal pressure of PN 30, making it suitable for high-pressure applications such as municipal water supply lines and industrial systems. The minimum operating temperature of -20°C means it can be used in unheated areas such as basements or external piping. The nickel-plated brass material ensures compatibility with potable water standards, as certified by ATEST. These specifications are crucial for selecting the correct valve size and rating for specific system requirements.

Installation and connection

Installation requires standard plumbing tools and knowledge of thread sealing practices. The valve features internal threads on both ends, allowing for direct connection to copper or plastic pipes. Ensure the pipe ends are clean and free of debris before threading. Apply a suitable sealing compound or PTFE tape to prevent leaks. Verify that the valve is fully tightened and aligned with the pipeline to avoid stress on the fitting. A common mistake is over-tightening, which can damage the sealing surfaces or cause thread stripping. Always double-check the direction of flow and ensure the valve is installed in the correct orientation.

Compatibility and accessories

This valve is compatible with standard copper and polyethylene piping systems. It can be used in conjunction with pipe unions, elbows, and other fittings to create a complete piping network. When installing in a new system, ensure that all connected components are rated for the same pressure and temperature conditions. No additional accessories are required for standard installation. However, in complex systems, consider using expansion joints or pressure-reducing valves to manage system fluctuations.

Technical background for designers

The ball valve operates by rotating a spherical disc with a bore to open or close the flow path. The CW617N material is selected for its durability and chemical resistance in water environments. The valve integrates seamlessly into water supply and heating systems, providing a reliable shut-off mechanism. Long-term performance depends on correct installation, regular inspection for leaks, and avoiding excessive pressure surges that could damage the sealing surfaces.

Service and operation

Periodic inspection is recommended to ensure the valve remains leak-free and functional. Check the sealing surfaces for wear or corrosion, especially after prolonged exposure to aggressive media. Ensure that the operating lever moves freely and that there is no binding in the stem. No scheduled maintenance is required unless the valve is exposed to unusual operating conditions. If a leak is detected, disassemble the valve carefully and inspect the seat and O-rings for damage.

Frequently asked questions
