Motorized Control Valve: Providing Control

A motorized control valve is able to manipulate the flow of liquid through piping systems. This manipulation occurs through the motorized control valve opening or closing to either allow or prevent a certain amount of liquid to pass through an opening at any given point in time. The valves can open or shut at any point during operations, which allow for flow to be controlled as needed during processes.

A motorized control valve can operate in response to a series of sensors, which allows everything to continually run smoothly throughout the entire course of operations. For example, more or less liquid flowing through a certain section of a system may be necessary if the temperature reaches a specific level, or if the pressure attains a certain measurement. The motorized control valve can be set to respond to these specific sensor readings, and then open or close as necessary to allow for the proper amount of liquid to stabilize and counteract the pressure and temperature conditions in the system.

The action of automatically opening and closing a motorized control valve is provided by different types of actuators. The actuators available to provide power for a motorized control valve that has been installed include electrical, pneumatic, and hydraulic actuators. These actuators respond to electrical, pneumatic, or hydraulic signals, respectively, and move the valve to different positions of partially open or partially closed as a response. The larger openings created by the motorized control valve translate to a larger volume of flow through the valve. Actuators provide different amounts of pressure to a system. Larger industrial systems may require the use of a pneumatic or hydraulic actuator, since these types of actuators can often provide more pressure than an electric actuator. The hydraulic and pneumatic actuators also require a pumping system in order to operate, and a company will need space for the entire system.

There are several different types of valve bodies available, and companies selecting a motorized control valve for installation can choose from a wide variety of options. These valve options include angle valves, globe valves, rotary valves, diaphragm valves, and sliding cylinder valves. Each of these valve categories contain options that are best suited to operate in certain specific conditions. A motorized control valve can be ordered with multiple ports, so that a system can install it in a location where different numbers of pipes come together for an intersection with lots of options for flow direction. Other types of valves may be selected by their cost, the materials from which they are made, the amount of resistance they provide to the flow passing through, or the sizes in which they are available. Most of the time, a motorized control valve can be specially ordered in an appropriate size for a business application. Sizing needs to line up with the piping system, in order for the valve to effectively form a tight seal when it is in the closed position and preventing liquid from entering.
