3.1. Power and rotor speed rotary valves
The following tables show the power and rotor speed for each type and size of DMN-
WESTINGHOUSE valve.
For good functioning of the valve the rotor tip speed must not exceed 0.66m/sec.The
standard rotor speeds are usually between 15-25 RPM depending on size of valve.
The Power depends on the minimum required torque and rotor speed.
According to the ATEX directive the maximum velocity must not be
higher then 1 m/s and the maximum power of the motor gear unit is
not higher then 4 kW.
If higher velocity or power are required then please contact
DMN.
The ATEX approval ceases without prior consultation.
