STAP – NPT threads
Differential pressure controller size 1/2" - 2", adjustable set-point and shut-off function
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.
Features & Benefits

Ensures accurate differential pressure control.
Adjustable set-point and shut-off function
Delivers desired differential pressure ensuring accurate balancing. Shut-off function makes maintenance easy and straightforward.
Measuring point with drain option
Simplifies the balancing procedure, and increases its accuracy.
