IMI TA / Balancing valves / TA-BVS 140/143

TA-BVS 140/143 A steel balancing valve that delivers accurate hydronic performance in a wide range of applications. The TA-BVS 140/143 are available with flanges or welding ends and is ideal for use on heating and cooling systems (HVAC/R) and other oxygen-free water applications.

Key features >

Handle Equipped with a removable handle that ensures accurate and straightforward balancing.

>

Measuring points For simple, accurate balancing.

>

Steel body Fully welded body construction is light weight, easy to insulate and maintenance free.
