Directional control valve are operated via radio control.

The purpose of the Control Valve is to regulate the flow rate of fluids through pipes in the system. This is accomplished by placing a valve in the path of flow of liquid. It acts to offer resistance to the flow of a liquid, where the resistance and flow can be controlled by a signal from a process

After heavy oil heating mining into steam driving mining, forming a fixed steam injection pipeline, steam distribution and measured typical processes. Heavy oil development steam injection process crucial in three problems is steam assign, measurement and adjustable control.

The most common and versatile types of control valves are sliding-stem globe and angle valves. Their popularity derives from rugged construction and the many options available that make them suitable for a variety of process applications, including severe service.

ordinary locator adopts mechanical force balance principle work, namely jet flapper technology, mainly exist in the following fault types

High pressure restore valve: one type of valve structure, due to streamline internal contour and minimum fluid flow, it will disperse relatively few fluid energy.

Three-way valves are normally used as mixing or diverting valves to control the flow of liquids. The difference between the two applications is in the piping layout and the internal design of the valve.

In power plants, such as nuclear plants, steam control valves are outlined in the steam chest which is in communication with the saturated steam coming from the steam generator. The control valves in general include a valve bonnet mounted in a valve body. The valve bonnet carries an axially sliding
