VBF Series 2-way and 3-way flanged control ball valves are used either as isolation valves or control valves in closed loop hydronic HVAC systems, with chilled water or hot water, and glycol content up to 50% concentration.
Valves are available in sizes from DN50 to DN150, with DN50 to DN80 being PN25, and DN100 to DN150 is PN16. Vaves are suitable for use with 2-P on/off actuators, 3-P floating, or 0…10Vdc modulating actuators, and excel both in flow control and isolation application. Medium temperature range is -30...120°C. Leakage class IV (2-Way and A-port of 3-Way), and class III (B-port of 3-Way) according to EN 1349. 3-way valves may be used either as mixing valves or diverting valves.
