Operation of the Rotary Evaporator (Rotovap)

3. To close the system and thus activate the vacuum, turn the stopcock knob at the far end of the rotovap to align it with the vacuum (ie. turn until the arrow on the knob points straight down towards the attached tubing ie. knob is pointing to the “ON” position). The system is now under reduced pressure. 4.

Control Valve Sizing for Water Systems Spirax Sarco

A three-port valve will be ‘line sized’ when based on water travelling at recommended velocities (Typically ranging from 1 m/s at DN25 to 2 m/s at DN150). 10 kPa may be regarded as typical pressure drop across a three-port control valve. Aim for valve authority (N) to be between 0.2 and 0.5, the closer to 0.5 the better.
