Characteristics / Ordering Code
Ordering code
∆p/Q curves
Manatrol needle valve, optional with 30° poppet, V-notch,
or rectangular slot. The form of the throttle opening influ-
ences the accuracy of the flow setting, which depends
on the pressure and viscosity. The needle is made of
stainless steel and corresponds to a ring gap in the
valve body.
