Manual balancing valve LENO MSV-BD, size DN20, male thread 1" 003Z4102

Manual balancing valve – precision and reliability in every system

The LENO MSV-BD manual valve is an indispensable element in heating, cooling and domestic hot water systems. Its task is to precisely balance the flow, which translates to optimal system performance and user comfort. Model DN20 with a 1" external thread (003Z4102) is a solid solution for both professionals and demanding users.

Construction and application

The LENO™ MSV-BD valve combines setting and shut-off functions, offering exceptional versatility. It can be used in both supply and return circuits. Thanks to the ability to rotate the body by 360°, mounting and reading are extremely convenient. The setting lock function is particularly useful, preventing accidental adjustment. This valve is used in systems with constant flows, ensuring stable operation of the installation. Made of dezincification resistant brass (DZR) guarantees long-term operation even in difficult conditions.

Advantages and benefits

• Precise balancing: Enables optimization of flow in the installation, which translates to even distribution of heat or cold.
• Versatility: Setting and shut-off function in one valve – saving space and costs.
• Durability: DZR brass construction provides corrosion resistance and long life.
• Easy installation: Removable head facilitates installation and servicing.
• Built-in measuring connections: Adapted for 3 mm needles – allows precise flow measurement using Danfoss PFM 3000/4000 or other compatible devices.
• Setting lock: Prevents accidental change of settings, guaranteeing stable system operation.
• Drain valve: Allows easy draining of the circuit, which facilitates servicing and maintenance of the installation.
• Wide range of diameters: Available in various sizes, allowing adaptation to individual installation needs (DN15-DN50).
• Possibility of using compression fittings: For steel, copper and PEX pipes - provides flexibility during installation.

The LENO™ MSV-BD valve is an investment in the reliability and efficiency of your heating or cooling system. Its precision of execution and functionality will be appreciated by both professional installers and users who value comfort and energy savings. The maximum working pressure is 20 bar, and the operating temperature is up to 120°C, which ensures safe operation in most standard installations. The Kv coefficient for this model is 6 m³/h at full valve opening.
