Manual balancing valve LENO MSV-D DN 15LF 003Z7000

Manual balancing valve – precision and functionality in one

The LENO MSV-D DN 15LF manual balancing valve is a modern solution for precise flow control in heating and cooling systems. Made of high-quality brass (CuZn40Pb2 / CW617N), it ensures reliability and durability even in harsh conditions. Designed for both professional installers and end-users, it combines balancing and shut-off functions, offering versatile applications.

Design and application

The LENO MSV-D valve is characterized by a solid ball-based construction, guaranteeing 100% tightness after closing. The removable head facilitates installation in tight spaces, and the rotatable body with measuring ports (adapted for 3 mm needles) provides convenience during measurement and adjustment. It can be used on both the supply and return lines, increasing installation flexibility. A pressure class of PN 20 and a temperature range from -20°C to 120°C allow its use in a wide range of applications. A Kvs value of 2.5 ensures adequate flow for installations with a nominal diameter of DN 15.

Advantages for the installer and user

• Quick installation: Removable head makes work easier in limited spaces.
• Precise adjustment: Numerical pre-setting scale is readable from different angles, making it easy to set the desired flow.
• Safety: Locking of the setting prevents accidental changes, and the shut-off function guarantees full control over the installation. Additionally, the valve can be opened or closed with an Allen key in emergency situations.
• Versatility: The valve can be used for both balancing and shut-off, eliminating the need for additional components.
• Convenient measurements: Built-in measuring ports adapted for 3 mm needles facilitate control of installation parameters.
• Durability: Made of CW617N brass, it provides corrosion resistance and long-term operation.
• Bidirectional: Allows flow in both directions without affecting the accuracy of regulation.
• Status indicator: A colored indicator clearly informs about the opening or closing of the valve.

The LENO MSV-D valve is an investment in the comfort and efficiency of a heating or cooling system – regardless of whether you are a professional installer or an end-user.
