A rotary valve refers to a section of a valve whose opening is closed by a rotary actuator. Trunnion balls are employed in gas and oil lines to regulate the amount of gas or oil flowing through a pipe. The motion of the balls also allows control of the amount of gas flowing through the system.<br><br><br>Trunnion ball valves have been in use for decades and have proven their usefulness in several industries. In the oil industry, they are used in the automatic control valve assembly where an inbuilt motor or servo is used to rotate the ball in a predetermined pattern. This allows high flow rates to be obtained at low pressures. In the gas and oil production industry, the high flow rate offered by trunnion ball valves allows controlled and consistent higher pressure levels in the lines. In the plumbing industry, they are often used to lower the operating pressure in plumbing pipes by controlling the amount of water that flows through them.<br><br><br>Trunnion ball valves are available in several models in the market today. There are the push-fit, inline four position, and three position rotary valves; as well there are the four position rotary valves and the two position in-line rotary valve varieties. Let us see how these different types work and how they are used.<br><br><br>Push-Fit Trunnion Ball Valves: These type of valve can be directly installed in the line. For this, the mating sleeves would need to be threaded so that the valve could be threads too. The installation is simple and easy. In order to get the best out of the performance of the Trunnion ball valves, always go for the original equipment or factory original equipment.<br><br><br>Inline Four Position Ball Valves: These are also known as the push-fit four position ball valves. As the name says, these are installed inside the lines. However, they have their own advantages compared to the other types. As the mating faces of these ball valves are already pre-mated, the operating torque of these types of ball valves is limited to a certain degree.<br><br><br>Three-Position Rotary Valve: As the name says, these are installed in the three position where there is a complete flow of gas or oil. Unlike the other varieties, the maximum amount of gas flow can be achieved at only ninety degrees of angular movement. The rotary motion is simply limited by the size of the opening in the valve casing. This is one of the most common types of rotary valve available and is commonly used for the control of oil and gas supply to the engine.<br><br><br>4 Position Top Entry Ball Valve: On the other hand, this one is very similar to the 3 position one but only the oil flow is achieved at four different angles. This way, it achieves the best performance. The 4-position top entry ball valve has a one way valve actuator and is often called a self-contained valve.

The benefit of this type is that the actuator is located at the top or near the firewall opening.<br><br><br>There are various models of the Trunnion valves; the only difference is the way they open. The two types, which allow the most efficient flow of gas or oil are the single-arm and the three-way ball types. The one-arm type is suitable for a single arm rotary valve and the three-way ball type is suitable for two arms. They also differ in their operation styles. The three-way ball valve can be programmed with three ways, either as open closed or neutral flow.<br>
