STAP – DN 15-50

STAP is a high-performing differential pressure controller that keeps the differential pressure over the load constant. This delivers accurate and stable modulating control, ensures less risk of noise from control valves, and results in easy balancing and commissioning. STAP’s unrivalled accuracy and compact size make it particularly suitable for use on the secondary side of heating and cooling systems.
