Manual balancing valve LENO MSV-D DN 15 003Z7001

Manual balancing valve – precision and versatility in every system

The LENO MSV-D manual balancing valve is a modern solution for precise flow regulation in heating and cooling installations, as well as domestic hot water systems. Designed for easy installation and operation, it performs well in both new and existing installations. Its versatility will be appreciated by both professional installers and end-users looking for a reliable way to optimize system performance.

Construction and application – the key to efficient operation

The LENO MSV-D valve combines flow balancing and shut-off functions, reducing costs associated with installing additional components. Made of high-quality brass (CuZn40Pb2 – CW617N), it ensures durability and corrosion resistance. A pressure class of PN 20 guarantees safe operation under typical conditions. The ability to mount on the supply or return line provides flexibility during installation. A Kvs value of 3 (for DN 15) allows for precise flow adjustment to the needs of a specific heat consumer.

This valve is used in:

• Heating boilers
• Residential heating units
• Heat pumps
• Single-pipe installations – for balancing branches
• Systems with radiators and other heat consumers

User comfort and easy installation

The LENO MSV-D valve stands out with a number of features that facilitate both installation and subsequent operation:

• Removable head: Allows for easy installation in tight spaces. Simply remove the knob to access the connections.
• Clear setting scale: The numerical preset scale is clearly visible from different angles, making it easy to precisely adjust the flow.
• Setting lock: Prevents accidental changes to the settings by unauthorized persons.
• Measuring connections: Built-in connections adapted for 3 mm needles allow for easy flow measurement and verification of the correctness of installation balancing.
• Shut-off function: When the valve is locked, it becomes a tight ball valve, allowing for complete flow shut-off without affecting the previously set level of regulation. This means there is no need to readjust after reopening the valve.
• Open/close indicator: A colored indicator clearly informs about the current status of the valve (open/closed).
• Emergency opening/closing: The valve can also be operated with an Allen key in emergency situations or when the knob is damaged.

The valve is designed to work with hot water and has a leakage class A according to ISO 5208, which guarantees its reliability and long-term use.
