Manual balancing valve LENO MSV-BD, size DN15, external thread 3/4" 003Z4101

Manual balancing valve for precise flow control

The LENO MSV-BD manual valve is a reliable solution for hydraulic balancing of heating, cooling and domestic hot water systems. Its design combines setting and shut-off functions, providing versatility and precision in flow regulation. It is ideal for both new installations and for modernizing existing systems.

Construction and application

The MSV-BD valve is designed for mounting on supply or return lines, allowing for optimization of flow in secondary circuits. Thanks to the ability to rotate the body by 360 degrees, access to the adjustment elements is easy from any side, which facilitates servicing and measurements. Made of dezincification-resistant brass (DZR), it guarantees long-lasting and trouble-free operation even in difficult conditions. This model is particularly recommended for systems with constant flow, where precise regulation is crucial for the energy efficiency of the system.

Key features and benefits

• Precise adjustment: Manual pre-setting allows for accurate flow adjustment according to the hydraulic requirements of the installation.
• Shut-off function: The valve also functions as a shut-off valve, allowing isolation of sections of the installation for service or repair purposes.
• Durable construction: Made of DZR brass, it provides corrosion resistance and long life.
• Easy installation and servicing: Removable head facilitates installation and replacement of elements if necessary.
• Measuring connections: Built-in connections adapted for 3 mm needles allow for precise flow measurement using external measuring devices (e.g. Danfoss PFM 3000/4000).
• Versatility: Available with external thread (3/4 inch) which facilitates integration with various types of installations.
• Setting lock: The ability to lock the setting prevents accidental changes to the settings.
• Drain cock: Allows easy draining of a section of the installation during servicing or maintenance.

The LENO MSV-BD valve is an investment in the efficient and reliable operation of a heating or cooling system, providing user comfort and reducing operating costs. Its solid construction and precise workmanship guarantee long-term satisfaction for both professional installers and end users.
