Liquid handling in industrial processes commonly involves the provision of a pump to move the fluid in the desired manner. Industrial pumps operate best and longest when they are provided with inlet conditions within a range for which the pump is designed. Two...
Pneumatic actuators are used throughout the industrial process control field to provide remote or automated control of valve operation. This type of industrial valve actuator employs pressurized air to move a piston or diaphragm and apply force to the valve stem,...
Regenerative turbine pump have double row vanes cut in the rim. The impeller rotates within two liners into which annular channels have been milled. Liquid flows in at the suction and is picked up by the impeller vanes. In completing nearly one revolution in the...
In many industrial control applications, a motorized valve can be used in place of a pneumatically operated valve. Motorized valves use electricity and an electric motor to operate a valve. The spindle of the valve is connected to the motorized (electric) actuator via...
An actuator is a pneumatic, hydraulic or electrically operated device that supplies force and motion to open or close a valve. In a typical control loop, the controller compares a signal parameter from the process to a desired set parameter (set point) and then...
