In some cases, flow control valve bodies and ball joints may be positioned internally. The valve bodies and ball joints are generally constructed from steel, brass, aluminum or PVC.<br><br><br>A simple but efficient flow control valve is a two-handle rotary actuator with an output shaft seal that feeds into a scoop-tube actuator. A DC signal converts the rotary actuator power into a signal that can be amplified by a mixer and rectifier circuit. The signal then goes to a microprocessor, which processes the signal to regulate an output voltage in conjunction with an output signal, usually a water signal. The output signal controls the speed of the water flow through the pipes or other media used for the liquid level process control system.<br><br><br>A large variety of flow control valves are available in the plumbing hardware market. A wide range of commercial, residential and industrial applications are present in the plumbing hardware industry. A wide range of systems control valves are available to serve specific application needs. For example, there are a wide variety of flow control valve shapes and sizes to suit the diverse pumping system designs. For example, there are dome-shaped, globe-shaped, rectangular box-shaped or ball-shaped flow control valve bodies that are suitable for systems used in the aerospace industry and various building applications. In addition, there are various other types of valve bodies used for different applications such as for pressure transfer and temperature control.<br><br><br>A wide range of commercial applications include gas and oil pipelines, water pipelines, sewage treatment plants, the water delivery system, railway stations, power generation facilities, the oil and gas industry, air conditioning and refrigeration systems and the like. Thus, a wide variety of hydraulic flow control valves are available in the plumbing hardware industry.

Some examples of popular hydraulic flow control valves include:<br><br><br>Ball-bearing orifice: A ball bearing orifice flow control valve is generally used as a sender with a fixed orifice. As the name implies, it has a ball or dome-shape contact surface on one side with an inlet pipe or fitting and an outlet pipe or fitting. The ball orifice determines the rotary motion of the valve and regulates the flow of fluid into the pipe. It ensures adequate flow of the fluid when the valve is closed and vice versa when it is opened.<br><br><br>Fixed orifice: A fixed orifice flow control valve is used as a sender having a variable pressure. It is typically smaller than the ball bearing orifice type of valve because the fixed orifice does not have a dome-shaped contact surface on either side with an outlet or inlet pipe fitting. When the valve is open, the pressure increases across the fixed orifice until the fluid stops flowing into the outlet pipe. However, when the valve is shut, the increased pressure in the system results in a decrease in the flow of fluid into the outlet pipe.<br><br><br>Ball needle valves: Ball needle valve stems are also called hydraulic flow control valves. They function by varying the rotational force between two adjacent needle valves. Typically, a ball needle valve stem has two needle valves in its body. The ball needle typically has a larger area than the other needle.<br><br><br>Energy transfer: There are many kinds of flow control valves including hydraulic, ball and needle. Each one has its own specific uses. As such, the amount of energy transferred to the fluid depends on the type of the valve used. A few common examples of these are:<br>
