Gas ball valve G24 - with integrated pressure plug - 5/4 "x1"; corner in axis IVAR.G24-MRR

Product detailed description

This gas ball valve is commonly used in residential and commercial gas supply lines, particularly in systems requiring regular integrity checks and pressure testing. It allows for safe and efficient measurement of operational overpressure and enables leak testing without the need for disconnection or professional intervention. The valve is ideal for integration into gas piping systems where compliance with safety regulations such as STN EN 1775/2008 is required. Its compact design and integrated pressure plug make it suitable for both new installations and retrofitting in existing systems.

Technical parameters

Material	Brass
Operating temperature	-20 °C
Nominal pressure	PN 5
Code	G2431B0300
Brand	IVAR

The valve is rated for a nominal pressure of PN 5 and can operate in environments with temperatures ranging from -20°C to +60°C. These parameters are essential for determining compatibility with gas systems and ensuring correct sizing for pressure and thermal conditions. The brass construction provides resistance to corrosion and ensures long-term reliability in a variety of installation settings.

Installation and connection

The IVAR G2431B0300 is equipped with a 5/4" x 1" connection size, allowing for secure integration into standard gas pipe configurations. During installation, the fitting should be aligned with the pipe axis to ensure proper sealing and flow control. A prevailing torque nut is used to secure the connection, reducing the risk of loosening due to vibration. Installers should verify the alignment of the valve body with the pipe and ensure that all connections are tightened to the manufacturer’s specifications. Common installation errors include misalignment, which can cause leaks, or over-tightening, which may damage the threads or sealing surfaces.

Compatibility and accessories

This valve is compatible with standard gas pipe systems using 5/4" x 1" fittings. For accurate pressure testing, a pressure gauge and measuring adapter may be required. The integrated pressure plug eliminates the need for additional components during routine testing. No specific accessories are listed as mandatory for operation, but installers should ensure that all connections are properly sealed and compatible with the system’s pressure rating.

Technical background for designers

The valve operates via a ball mechanism that allows or blocks gas flow depending on the position of the handle. The integrated pressure plug enables direct access to the internal pressure for testing purposes without the need to open the system. The brass material offers durability and resistance to both mechanical stress and environmental factors. The TECOBLOCK® safety system prevents accidental opening, enhancing operational safety. The design ensures minimal pressure drop and consistent flow characteristics, making it suitable for both low and medium-pressure applications.

Service and operation

Routine maintenance involves visual inspection of the valve body and connections for signs of wear, corrosion, or leakage. The pressure plug should be checked for tightness and integrity after any system pressure test. No scheduled service intervals are specified, but periodic checks are recommended to maintain system performance. The valve’s design allows for easy access to the pressure plug for testing, ensuring that maintenance can be carried out without disrupting gas flow elsewhere in the system.

Frequently asked questions

Can the pressure plug be removed without professional tools?
Yes, the pressure plug can be accessed and removed without requiring professional tools or certification, as the process does not involve gas release.

Is the valve suitable for high-pressure gas lines?
No, the valve is rated for a maximum pressure of PN 5 and is intended for low to medium-pressure applications only.

How does the TECOBLOCK® system prevent accidental opening?
The TECOBLOCK® system uses a locking mechanism that requires deliberate action to override, preventing unintentional valve rotation during operation.

Can this valve be used in outdoor installations?
Yes, provided the installation is protected from extreme weather conditions and the temperature range remains within the specified limits of -20°C to +60°C.
