Control ball valve
BOFB...K...B (2-way valve)
BOLB...K...B (3-way valve)
Description
The ball valve is used to control the flow of hot and cold
water and Glykol solutions (max. 30%) in HVAC systems
conjunction with a rotary actuator
Simple actuator mounting
3-point or continuous control
Combination with spring return and without spring
return
Runtime changes possible
