There are different types of Equipco Australia control valves. The control valves contain a pneumatic device. The device converts the control signal from the controller which in turns regulates the process of fluid flow. Refinery and chemical processing industries spend approximately 15% of their total expenditure on valves. Companies use valves to handle a variety of gases, liquids, air, steam and more. Here are different types of valves and their applications.
These types of valves are known by a siding gate. The gate is moved by a stem to flow’s perpendicular direction. Gate valves are used for an on-off application. They are recommended for high pressure and high-temperature use with a variety of fluids. They aren’t primarily used for viscous fluid and slurries. The main advantage of using gate valves is that low pressure drops when the valve is fully open. However, the valve also has its disadvantages in that it causes vibration which makes the seat disc to wear out when it is partially open. The valve also has slow response features and need a large force that actuates.
The pug or the disc in globe valves is moved on or off the seat. The opening of the seat is directly proportional to the plug’s travel. The valve has high flow controllability, high seating capacity, large pressure drop and short stem travel. The main application of the globe valve is for throttling purposes. It is also considered to be a general purposes valve for flow control in high-temperature application. When you buy high-quality Equipco valves Australia, the globe valve has some advantages. The valve is faster to close and open, has a positive shut off and it is the most reliable form of seating. The disadvantage of the valve is that the seat disc wear when it is opened partially. The advantages outweigh the disadvantages.
It consists of the plug, body and cover. The plug valve can be cylindrical or tapered. The bore in the plug connects the outlet and the inlet ends in the open position and this provides a straight line flow. The plug valves are mainly used in petrochem, refinery and chemical industries for general purpose. The plug valves come in a wide range of materials. They are normally small in size and require less headroom. Their shut off is tight. However, the valve may be subjected to galling and that is the main disadvantage of the plug valve.
The ball valve is typically an improvisation of the plug valve. The valve is spherical and that is why it is called the ball valve. It has a seat that matches the ball so that the stress caused by the sitting is uniform circumferentially. The seats of ball valves are made up of a material that is inert to chemicals and has a low coefficient of resiliency and friction. The material is known as PTFE. You can buy Equipco Australia ball valves for pressure and flow control and shut off for slurries, corrosive fluids, gases and normal liquids. The valve can also be used for high pressure and high-temperature applications.
