Flow Control Methods

Flow Valves

Flow Valves are usually Ball Valves with electrical actuator motors (rotary or linear) or hydraulic actuator. By

changing the opening of the valve, the flow of liquid is varied. Note that flow is proportional to boom

pressure. Also control of Gas Motor pumps using linear motor actuator.

Flow Motors – Electric and Hydraulic

Flow motors will be connected directly to the Pump. By varying the RPM of the pump, the Liquid flow can

be controlled directly without the need for a flow valve. These systems can not only control flow, but also

control the on/off of flow. If tank mixing is necessary, then a Bypass on/off should also be installed.

Fan Control

Some Fans have a variable pitch system. These can be set up to have an actuator to control the pitch thus

control the flow of the liquid. Usually, these systems have a fan brake for On/Off control.
