'<br>As discussed in previous articles, an actuator valve is a two-piece ball valve found in hydraulic systems that convert air into either hydraulic pressure or hydraulic fluid. Because the actuator comprises two balls and the valves are situated at different ends of the system, a design known as double-acting refers to them. Typically, the valve is a brass to PVC adapter with a stem fitting at its end. The valve body, made of brass, is called an actuator stem and is surrounded by a hose. This hose serves to transmit the hydraulic signal to the appropriate line or control. The valve is designed so that when one ball lifts, the other ball drops.<br><br><br>There are three types of actuator valve bodies available for use with hydraulic systems. A single valve body allows a single actuator to be used, whereas dual-acting and multiple-acting bodies are used to provide greater control.

The advantage of a single actuator valve is that only one ball must lift in order for the signal to be transmitted. If two balls are present, then additional signals must be transmitted from one valve to the other in order to activate them. However, both types of actuator valve bodies are effective and provide reliable control.<br><br><br>Single-actuator valve actuators are available with either a spring return or pressure return assembly. Spring return assemblies enable the actuator valve to lift and lower itself without the help of another part, thus improving reliability. When selecting a return spring assembly, make sure you select those with large operating torque for maximum performance. Hydraulic systems with a high degree of complexity usually have their own spring return assembly, but some actuator valve manufacturers combine these components into a single package.<br><br><br>A valve actuator assembly serves as a safety device in areas where it may be dangerous to have a ball return assembly. An example of an unsafe area where this type of assembly is needed is a hazardous area that produces or uses flammable or toxic fluids. In addition, some parts, such as chemical processing units, ovens, and power generating stations, may require special safety mechanisms such as an actuator assembly to prevent runaway reactions in areas where there is a risk of fire. For example, a flammable liquid may leak out due to a faulty valve actuator assembly; if an area were to be left unchecked, there is a danger of explosion.<br><br><br>Pneumatic actuators, also known as pump actuators, are available with a variety of different air supply and power source configurations. There are two major types of actuator valve available on the market; gas and electric. Although there are many variations between the two types, most gas and electric valve actuators are widely available. Gas and electric air supply systems have the following advantages; they are highly efficient because of their larger stream capacities and lower required energy; they can be easily maintained; they are available in a variety of different styles, which allows for an easy upgrade when necessary; and they can be inexpensive and reliable. The primary disadvantage of gas and electric actuator valve systems is that they take up more space and must be installed in a ventilated area.<br><br><br>Single True Union (SUN) actuator valve systems are often used to control the flow of liquid through a single valve or in a series of valve arrangements to control the flow of a large volume of liquid. As their name indicates, a single true union allows for single control of the actuator valve; however, this feature does come at a cost. Single true unions can have variable speed actuators and can have a manual control feature. Some single true unions are available with an electronically adjustable valve lift, which allows for the addition of actuation force for purposes of regulating the amount of back pressure exerted on the actuator valve. These valves also allow for the adjustment of pressure through the use of a variable valve lift.<br><br><br>Full Swing Actuators (FSA) is a relatively new type of actuator valve, as they use a combination of both swing and gate valve actuators. In contrast to the split and single true unions, the swing and gate actuators move in only one plane. The benefit of this design is that the valves are capable of full operation at any point along their travel path; however, full swing actuators must be manually controlled. Similarly, gate actuators must be manually controlled during operation.<br><br><br>Swing and gate ball valve types are commonly found in applications requiring an effective relief angle for high pressure swing or gate operations. Swing ball types typically have a higher degree of mechanical freedom than do gate ball valve types, including: greater angle of control, greater water control, and the ability to vary the level of hydraulic pressure in accordance with external water pressure and environmental factors such as temperature. Gate ball types can also be used to provide a source of relief in high flood conditions where the amount of water flowing out of the pipe would exceed the capacity of the pipe.<br>'
