Suitable for replacement or installation in residential and commercial hydronic heating systems.

## Long description

The Danfoss LENO MSV-D Valve DN20 with female thread is a thermostatic radiator valve insert designed to control flow and balance radiator circuits in hydronic heating systems. As a DN20 component it matches standard 3/4" nominal female threaded connections and is intended for installation or replacement inside compatible valve bodies. The valve insert offers proportional flow control related to temperature settings and supports stable temperature regulation in residential and light commercial applications.
Advantages
The LENO MSV-D valve insert provides accurate flow control and helps maintain consistent radiator output across a heating circuit. Its DN20 female thread compatibility simplifies integration with common plumbing fittings and radiator valves. The thermostatic functionality improves energy-efficient temperature regulation by adjusting flow according to room temperature demands, which can reduce overheating and contribute to system balancing.
Suitable for
 Replacement of DN20 (3/4" nominal) thermostatic valve inserts in radiators
 Installation in residential hydronic heating systems
 Use in small commercial radiator circuits requiring temperature control and balancing
 Applications where a compact, in-line thermostatic valve insert is needed
When it may not be suitable
This valve insert is designed specifically for DN20 female threaded connections and may not fit systems with different thread types or sizes. It is intended for use as an insert in compatible valve bodies; it is not a complete valve assembly and therefore requires an appropriate housing or radiator valve body for installation.
Key specifications
 Valve type: Thermostatic radiator valve insert
 Connection size: DN20 (nominal 3/4") female thread
 Function: Proportional flow control for temperature regulation and circuit balancing
 Application: Hydronic heating systems (residential and light commercial)
 Form factor: Compact insert designed for installation in compatible valve bodies
How to use
Shut off the heating system and drain the section of the circuit before removing the existing insert or valve. Unscrew the old insert from the valve body and install the Danfoss LENO MSV-D by threading it into the compatible DN20 female connection until securely seated, following torque recommendations of the valve body manufacturer. Refill and vent the system, then test operation under normal conditions. Adjust the thermostatic head or actuator on the valve body to achieve the desired room temperature and allow the system to stabilize.
What to consider before purchase
 Confirm the valve body accepts a DN20 (3/4" nominal) female threaded insert
 Check compatibility with the thermostatic head or actuator intended for use
 Verify the insert form factor fits within the existing radiator valve housing
 Ensure the heating system is suitable for a thermostatic control strategy
Usage recommendations
Install and commission the valve insert with the heating system cooled and depressurized. After fitting, bleed radiators to remove air pockets and run the system to observe temperature balance. For best results, combine the insert with compatible Danfoss or manufacturer-recommended thermostatic heads and follow local plumbing codes and manufacturer instructions for installation and maintenance.
