The device is designed for easy installation and commissioning, making it a practical choice for HVAC professionals aiming for efficient system setup.

Suitable for

  • Balancing flow in residential heating systems
  • Regulating water distribution in commercial cooling networks
  • HVAC installations requiring precise hydraulic adjustment
  • Closed-loop water systems in buildings

When it may not be suitable

This product is a manual balancing valve and is not intended for automated temperature regulation or dynamic flow control where motorized actuators are required. It is also not suitable for use in steam applications or with media outside the specified operating parameters of standard HVAC water systems.

Key specifications

  • Valve type: Manual balancing valve
  • Model: LENO MSV-D
  • Nominal diameter: DN40
  • Application: Heating and cooling systems

How to use

Installation should be performed by qualified personnel in accordance with standard plumbing and HVAC practices. The valve is integrated into the piping network at designated balancing points within heating or cooling circuits. Flow regulation is adjusted manually using the integrated control mechanism to achieve the required design flow rate and ensure balanced hydraulic performance throughout the installation.

What to consider before purchase

  • Verify that the DN40 size matches your pipe dimensions and flow rate requirements
  • Confirm compatibility with your specific heating or cooling system layout
  • Ensure that manual regulation meets the operational needs of your project
