STAD – NPT threads
Balancing valve DN 10-50, PN 25
The STAD balancing valve delivers accurate hydronic performance in an impressive range of applications. Ideally suited for use on the secondary side in heating and cooling systems, and tap water systems.
Features & Benefits
High accuracy for all settings
Ensure accurate balancing and flow reading.
Handwheel
Equipped with a digital read-out, the handwheel ensures accurate and straightforward balancing. Positive shut-off function for easy maintenance.
Self-sealing measuring points
For simple, accurate balancing.
