Gas ball valve - under plaster, TC 3/4" x TC 3/4"

Product detailed description

This under-plaster gas ball valve is commonly used in residential and commercial buildings for controlling gas flow in domestic gas distribution systems. It is installed behind plaster or within walls, providing a compact and concealed solution for gas shut-off. The valve is suitable for natural gas, liquefied petroleum gas (LPG), and other gas types as defined by EN 437 and DVGW G260/1 standards. The installation requires careful alignment with the gas supply line and proper sealing to ensure safe operation and prevent gas leaks.

The valve is typically used in conjunction with gas appliances such as boilers, cookers, and water heaters. It is designed for easy installation and reliable operation in environments where space is limited and aesthetics are important. The valve is supplied with an installation box but without a cover plate, requiring the installer to complete the final finishing according to the building's interior design.

Technical parameters

Material	Brass
Operating temperature	-20 °C
Nominal pressure	PN 1
Weight	0.499 kg
Code	K200BC10100
Brand	IVAR

The operating temperature range of -20 to +60 degrees Celsius allows the valve to function in both cold and warm environments. The PN 1 rating indicates the valve is suitable for low-pressure gas systems. These parameters are essential for selecting the correct valve for the intended application and ensuring compatibility with the gas supply system.Installation and connection The valve is connected using internal thread (TC) connections of 3/4 inch. The installation process involves securing the valve within the installation box and connecting it to the gas supply line using appropriate sealing materials. It is important to verify that the thread is clean and undamaged before tightening to prevent leaks. Common installation mistakes include over-tightening the connections, which can damage the sealing surfaces, and failing to align the valve properly within the installation box. The valve should be installed in an accessible location to allow for future maintenance and inspection.Compatibility and accessories The valve is compatible with standard gas piping systems and is suitable for all gas types defined by EN 437 and DVGW G260/1. It is typically used with copper or steel gas pipes and requires appropriate sealing materials such as PTFE tape or sealing compound. The installation box is included, but a cover plate must be ordered separately to complete the finish. No additional accessories are required for basic installation.Technical background for designers The gas ball valve operates by rotating a spherical disc with a hole through it, allowing or blocking gas flow when the hole is aligned or perpendicular to the flow direction. The valve body is made of brass, a durable and corrosion-resistant material suitable for gas applications. The sealing surfaces are designed to maintain a tight shut-off even after repeated use. The valve is integrated into the gas distribution system as a primary shut-off device, and its performance is influenced by the quality of the installation, the condition of the sealing materials, and the operating conditions such as temperature and pressure.Service and operation The valve requires minimal maintenance due to its simple design and durable materials. Regular visual inspections should be carried out to check for signs of wear, corrosion, or gas leaks. The sealing surfaces should be kept clean and free from debris to ensure a reliable shut-off. No specific service intervals are defined in the technical data, but the valve should be inspected during routine maintenance of the gas system.Frequently asked questions
