Gv. internal - internal, 1/2" FF

Product detailed description

Internal-threaded ball valves are essential components in plumbing and heating systems where secure shut-off of water or non-aggressive media is required. They are commonly used in residential, commercial and industrial buildings for isolating sections of pipe during maintenance or repair. The IVAR 8363R004 model is specifically designed for use in water supply systems, irrigation, and HVAC applications where the media is non-corrosive and the operating conditions are within standard temperature and pressure ranges. The valve is intended for use in systems with internal-threaded connections and is suitable for both new installations and system upgrades. It is important to ensure that the valve is installed in a location that allows for easy access during operation and inspection.

Technical parameters

Material	Nickel-plated brass CW617N, approved for potable water
Operating temperature	-20 °C
Nominal pressure	PN 50
Weight	0.136 kg
Code	8363R004
Brand	IVAR

The PN 50 pressure rating indicates that the valve is suitable for systems operating at up to 50 bar. The temperature range from -20°C to +120°C makes it suitable for use in cold and hot water systems. The nickel-plated brass CW617N construction ensures compatibility with potable water systems and provides resistance to corrosion and wear. These parameters are essential for correct sizing and selection in accordance with system requirements and standards.

Installation and connection

The valve is designed for internal-threaded (FF) connections and must be installed in a straight section of pipe to ensure proper alignment and prevent stress on the valve body. The recommended minimum distance from the valve to any welding or bending is 20 cm to avoid heat transfer and mechanical stress. The valve must not be subjected to impact or torsion during installation. The internal components are sealed and bonded, and any attempt to disassemble the valve will compromise its integrity and must be avoided. The valve must be installed in a position that allows full movement of the lever without obstruction. Common installation errors include misalignment of the pipe, failure to check the lever movement before tightening, and applying excessive force during installation.

Compatibility and accessories

The valve is compatible with standard internal-threaded pipe systems and is suitable for use with copper, steel and plastic piping. No additional accessories are required for standard installation. The valve is not designed for use with aggressive or chemically corrosive media. It is recommended to use standard pipe fittings and tools for installation. The valve must not be combined with other components that require disassembly or modification of the valve body.

Technical background for designers

The valve operates on a ball mechanism with a specially shaped ball and sealing profile to reduce contact surface and prevent sediment buildup. The nickel-plated brass CW617N material provides durability and resistance to corrosion, making it suitable for potable water applications. The valve is designed for integration into systems where reliable shut-off is required without the need for regular maintenance. The operating principle ensures minimal friction and wear, extending the service life of the valve. The design also minimizes the risk of leakage and ensures a tight seal when closed. The valve must be installed in a system that maintains alignment and avoids mechanical stress to ensure optimal performance.

Service and operation

The valve is designed for maintenance-free operation and does not require regular servicing. However, it is recommended to operate the valve fully once every six months to prevent sediment buildup and ensure smooth operation. The valve must not be disassembled or modified in any way, as this will void the warranty and compromise its integrity. Any damage to the valve, except for the lever or handle, must be addressed by replacing the entire unit. The maximum allowable temperature of 185°C must not be exceeded, as this can cause deformation or failure of the valve components.

Frequently asked questions
