Manual balancing valve LENO MSV-BD, size DN32, internal thread 1 1/4" 003Z4004

Manual balancing valve – precision and reliability in your installation

The LENO MSV-BD manual balancing valve is a reliable solution for precise flow regulation in heating, cooling and domestic hot water systems. The device, made of dezincification resistant brass (DZR), guarantees long-lasting and trouble-free operation even in difficult conditions. The DN32 model with a 1 1/4" internal thread is universal and easy to install.

Functionality and design for professionals and users

The LENO MSV-BD valve combines setting and shut-off functions, making it a versatile element of the installation. The removable head facilitates installation and servicing, and the 360° rotatable body provides convenience during measurements and draining. The built-in drain cock allows separate draining of water on the supply and return sides, which is particularly useful during maintenance. A precise setting scale with a lock prevents accidental adjustment. Additionally, the valve has measuring connections adapted for 3 mm needles, allowing accurate flow measurement using Danfoss PFM 3000/4000 or other meters available on the market.
