Flanged Ball Valve - Series B2.1 for Gas - DN 32; L=130mm BRA.B2.100 GAS

Product detailed description

Flanged ball valves are essential components in gas distribution and processing systems. They are commonly used in industrial facilities, power plants and commercial buildings where precise control and reliable shut-off are required. These valves are integrated into gas pipelines to manage flow direction and isolate sections for maintenance or safety. Installers and technicians working in gas infrastructure will find this valve suitable for applications involving gases classified under G1 and G2 according to PED 2014/68/EU. The valve is designed for use in environments with temperatures ranging from -10°C to +70°C, making it adaptable to a wide range of operational conditions.

The valve is constructed with a full-bore design for unrestricted flow and is compatible with actuators for automated control. Its flanged connections conform to EN 1092-1 standards, ensuring secure and leak-free installation in pressurised gas systems. The body material and sealing properties are selected to withstand the mechanical and chemical demands of gas applications. This valve is not suitable for steam or flow regulation due to its design constraints.

The nominal diameter of DN 32 ensures compatibility with standard pipe sizes in gas systems. The PN 16 rating indicates a maximum allowable working pressure of 16 bar, which is critical for selecting the correct valve for the intended application. These parameters help ensure that the valve can handle the expected flow rates and pressure levels without compromising performance or safety.Installation and connection To install the flanged ball valve, align the flange faces with those of the pipeline and secure using appropriate bolts and gaskets. Ensure that the flanges are parallel and evenly tightened to prevent leaks. The valve is equipped with ISO 5211 mounting for actuators, which should be aligned during installation. Common installation mistakes include misalignment of flanges, improper tightening of bolts and incorrect orientation of the valve. Always verify that the valve is fully open before tightening to avoid damaging the internal components. Check that the flange faces are free from debris and that the gasket is properly seated between the flanges.Compatibility and accessories This valve is compatible with gas systems operating within the specified pressure and temperature ranges. It is designed to work with actuators that conform to ISO 5211 standards for automated control. When ordering, ensure that all necessary mounting hardware and gaskets are included for a complete installation. No specific related products are listed for this model.Technical background for designers The valve operates using a ball mechanism that rotates to open or close the flow path. The body is made from grey iron GJS400-15, providing strength and resistance to mechanical stress. The ball is constructed from brass CuZn40Pb2, while the stem is made from chrome-plated brass. The sealing surfaces use PTFE for the ball and two NBR seals for the stem, ensuring a tight closure and minimal wear. The full-bore design allows for unimpeded flow, reducing pressure drop and energy loss. The valve’s performance is influenced by the quality of the installation, the condition of the pipeline and the operating environment. Avoid using this valve in steam or flow-regulating applications, as it is not designed for such purposes.Service and operation Periodic inspection of the valve is recommended to ensure continued performance. Check for signs of wear on the sealing surfaces and verify that the flange connections remain secure. Lubricate the stem as needed to maintain smooth operation. No specific service intervals are provided in the technical documentation. During routine maintenance, inspect the gaskets and replace if damaged. Ensure that the valve remains clean and free from contaminants that could affect its function.Frequently asked questions
