STAD-C

Balancing valve DN 15-50 with double secured measuring points

The STAD-C balancing valve has been specially developed for use in indirect cooling systems but performs just as effectively in refrigerated counters and cold-storage rooms. Whatever the application, the STAD-C delivers unrivalled hydronic performance.

Features & Benefits

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

Doubly secured and self-sealing for total protection against leakage. Also enable more straightforward maintenance.

AMETAL^®

Dezincification resistant alloy that guarantees a longer valve lifetime and lowers the risk of leakage.
