Manual balancing valve LENO MSV-BD, size DN50, internal thread 2" 003Z4006

Manual balancing valve – precision and versatility in heating installations

The LENO MSV-BD manual balancing valve is a reliable solution for precise flow control in heating, cooling and domestic hot water systems. Its versatility and functionality will be appreciated by both installers and end users. The valve design combines balancing and shut-off functions, which translates into cost savings and simplified installation. Made of dezincification resistant brass (DZR) ensures durability and corrosion resistance, guaranteeing long-term trouble-free operation.

Design and application

The LENO MSV-BD valve is characterized by a compact design that makes installation easy even in tight spaces. The ability to remove the manual knob further increases the installer's comfort. The 360° rotating body with drain cock allows for flexible adaptation to installation conditions and facilitates emptying and filling the installation from two sides. Built-in measuring ports adapted for 3 mm needles allow for accurate flow measurement, and their rotating design allows for optimal positioning relative to the measuring point. This valve is used in secondary cooling or heating circuits in distribution systems, where precise flow balancing is crucial for the efficient operation of the system.

Advantages and benefits

• 2-in-1 function: Flow balancing and shut-off in one valve – saving space and costs.
• Tightness: Thanks to the use of a ball shut-off valve, it ensures 100% system tightness after closing.
• Easy installation: Compact design and removable knob make installation easier in limited spaces.
• Precise measurement: Built-in measuring ports allow accurate flow measurement with standard measuring needles (3 mm).
• Versatility: Can be used in heating, cooling and domestic hot water systems.
• Durability: Made of dezincification resistant brass (DZR) ensures corrosion resistance and long life.
• Setting lock: Protects against accidental change of flow settings after adjustment.
• Wide Kv range: A Kv value from 1.74 to 40 allows the valve to be adapted to different installation parameters.
• Rotating body: Allows convenient access to the drain cock and measuring ports from any side of the valve.

The LENO MSV-BD valve is compatible with Danfoss PFM 3000/4000 measuring devices, which facilitates diagnostics and optimization of the heating or cooling system. The use of this valve translates into efficient energy use, user comfort and reduced operating costs of the installation.
