Types of Trunnion Ball Valves

 Types of Trunnion Ball Valves 

A trunnion mounted ball valve or a trunnions ball valve, if you want to call it that, is used in the hydraulic systems of almost every industry. However, it has a unique feature that is different from any other valve: when the piston moves into a closed position, it becomes a trunnion ball or a floating valve; but when the piston moves into an open position, it becomes a floating valve or a trunnion roll. In fact, there are more types of valves than these three, and they all have different features and functions.

 

When the piston moves into a closed position, it is known as a trunnion roll; but when the piston moves into an open position, it is called a floating trunnion valve. As the ball moves inside the piston, the trunnion rolls will slide over the top of the piston will move up and down by its own motion. The key to the operation of these valves is that they can be opened and closed according to the need. Let us take a look at some examples. 

The first example of a trunnions ball or a floating valve that can be used in a hydraulic system is the roll type. This type of trunnion is most commonly found in oil-filled pumps. With this type, a valve can be opened when oil is pumped inside the pump, or it can be closed when the pump stops pumping oil. 

Another trunnions ball or a floating valve that can be used in a hydraulic system is the piston ring type. With this type, the piston is stationary and the ring moves over top of it. This type of valve is commonly found in https://rizziovalvole.com/api-6d-trunnion-ball-valve/ the compressor, blower and compressors. It is designed to maintain a constant pressure of air, allowing the air to fill the cylinder without causing a loss of air pressure, and thus keep the pump running smoothly. 

The third type of trunnions ball or a floating valve that can be used in a hydraulic system is the ring-type. Here, the piston is movable and the ring is moved over top of it. This type of valve will give you a variation of pressure depending on how far the piston moves and what the condition of the pump is at the moment. 

These are the three types of valves that can be used in a hydraulic system. There are many other types and you should be able to choose the one that fits your needs and your type of system.
