Manual balancing valve LENO MSV-BD, size DN15 LF - low flow, female thread 1/2" 003Z4000

Manual balancing valve – precision and versatility in every system

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 stems from the combination of a setting and shut-off function in one device, which translates to space and cost savings. The construction based on a ball valve guarantees 100% tightness, and the ability to remove the knob facilitates installation in tight spaces.

Construction and application

The LENO MSV-BD valve is designed for ease of use and durability. Made of dezincification resistant brass (DZR), it provides corrosion resistance and long life. It has built-in measuring ports, and in the MSV-BD model, 360° rotatable measuring ports and a drain cock allow for flexible adaptation to installation conditions. The ability to drain/fill from both sides of the valve further increases user comfort. This valve is perfect for both new installations and the modernization of existing systems.

Key features and benefits

• 2-in-1 function: Flow balancing and shut-off in one valve – reduces costs and simplifies installation.
• Tightness: Construction based on a ball valve ensures complete tightness, eliminating the risk of leaks.
• Easy installation: Compact dimensions and the ability to remove the knob facilitate installation even in limited spaces.
• Precise adjustment: Built-in measuring ports allow for accurate flow setting, which translates to optimal system performance.
• Versatility: Can be used in installations with various working fluids – drinking water (after using appropriate accessories), central heating water and ethylene glycol.
• Setting lock: Protection against accidental change of initial settings by means of a knob lock or sealing strip.
• Wide range of parameters: Available Kv value range from 0.07 to 2.53 allows you to choose the right valve for specific installation needs.
• Durability: Made of DZR brass guarantees corrosion resistance and long-term use even in difficult conditions.

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. Pressure class PN 20 ensures safe operation under standard operating conditions, and nominal diameter DN 15 (LF version – low flow) makes this valve ideal for use in installations with lower performance.
