Flanged Ball Valve - Series B1 - DN 40; L=65mm BRA.B1.000

Product detailed description

Flanged ball valves are essential components in industrial and commercial plumbing and HVAC systems. They are commonly used in heating, ventilation, and air conditioning systems, as well as in water distribution and compressed air applications. These valves provide reliable shut-off and are frequently installed in systems where maintenance and accessibility are important. This model is suitable for systems operating within a temperature range of -10°C to +100°C and is designed for use in environments where durability and resistance to corrosion are required.

When selecting a flanged ball valve for installation, it is important to consider the system’s operating pressure, media type, and temperature range. This valve is intended for use with water, heating systems, and compressed air, but is not suitable for steam or flow regulation. The valve is constructed to meet the requirements of EN 1092-1 for flange connections and is compatible with ISO 5211 actuators for automated control.

Technical parameters

Installation and connection

Installation of this flanged ball valve involves aligning the flange faces with the corresponding pipe flanges and securing them with bolts. The valve is equipped with PN 16 flanges according to EN 1092-1, which must be matched with compatible flanges on the piping system. The maximum recommended torque for tightening the bolts should be followed to avoid over-tightening and potential damage to the sealing surfaces. It is important to ensure that the valve is installed in a position that allows for easy access and maintenance. Common installation mistakes include misalignment of flanges, use of incorrect gaskets, and failure to follow the manufacturer’s torque specifications.

Compatibility and accessories

This flanged ball valve is compatible with standard HVAC and plumbing systems that use DN 40 piping and PN 16 flange connections. It can be used in conjunction with actuators that conform to ISO 5211 for automated operation. When installing, it is important to ensure that the system’s piping and fittings are also rated for the same pressure and temperature conditions. No additional accessories are required for basic operation, but actuators or control systems may be added for remote operation.

Technical background for designers

The valve operates by rotating a spherical disc with a bore that aligns or blocks the flow path. The ball is made of chromium-plated brass (CuZn40Pb2) and is sealed against the valve body using PTFE, which provides low friction and good sealing properties. The body is made of grey cast iron (GJL250), which offers good mechanical strength and resistance to thermal expansion. The valve is designed for full flow capacity and is suitable for use in systems where a tight shut-off is required. The operating principle ensures minimal pressure drop and high flow efficiency, making it ideal for applications where flow control is not required but reliable isolation is necessary.

Service and operation

Regular inspection of the valve is recommended to ensure continued performance. Key checkpoints include verifying the integrity of the flange connections, checking for signs of leakage around the sealing surfaces, and ensuring that the valve operates smoothly without resistance. No specific service intervals are provided in the technical data, but maintenance should be performed as part of routine system checks. The valve is designed for long-term use with minimal maintenance, provided that it is installed correctly and used within its specified operating conditions.
