for VAG60.. and VBG60.., for details, see table on equipment combinations
Δp
max
=
Maximum permissible differential pressure over the ball valve, valid for the entire positioning range
of the ball valve rotary actuator unit; if low noise operation is desired, we recommend a maximum
permissible differential pressure of 200 kPa
Δp
v100
= Differential pressure over the fully opened ball valve and over the control path at a volume flow V
100
100
= Volume flow through the fully opened ball valve
100 kPa = 1 bar ≈ 10 mWS
