A ball valve, also known as ball plug valve, is a rotary action valve that is quarter turn. It has seats and spherical closure. It is important to have some critical details about these types of valves before using or acquiring them.

Selecting the best ball valve

During shut off applications, you may be required to use a ball valve. Before you can settle on a certain type, consider a number of factors. This guide will help you select a ball valve that is durable and reliable. Consider the pressure handled by the valve before settling on the right valve size. Different valves are designed for different types of fluids. It is thus wise considering the fluid being handled by the valve. The amount of fluid flowing through the valve also determines the size of ball used. Consider the temperature of the fluid flowing through the valve as well. Before selecting a ball valve, you should consider the installation cost required as well as material and size composition of the valve.

Ball valve parts

It is important that one has inner details concerning the valve parts. They include bonnet, which covers the opening in the body of the valve. It is also the second pressure boundary. Another part is the actuator. It works with the internal parts of the trim. This part helps to run the disk and the stem. The trim is ball valve’s part that is made of different internal parts such as the disk sleeves, stem and the seat. Another part is the packing. This mainly helps to prevent leaking which may occur between the stem and bonnet. The part seals the internal parts of the valve. The body, or rather shell, is the framework of the valve since it holds all other parts of the valve together. This is the first pressure boundary part of the ball valve.

Ball valve maintenance

Valve parts are made of either rubber, metal or even plastic. They require cleaning to avoid reaction thus affecting performance. Metal parts can be cleaned using cleansing sprays, which are made from gas. Non-metallic parts can be maintained using alcohol. Cleaning these parts avert any damages that are mainly caused by corrosion and other unwanted reactions. This improves on the performance of the ball valve.

ANSI Ball Valves

The use of ball valves has been realized throughout many types of industies. The valves are known for their effective regulation of the fluid flow in pipes. The valves come in a spectrum of models with ANSI ball valves being very efficient. A two-way ANSI flanged, full port ball valve has various parts that are relevant to its operation. It has a stem, ball and a body cover. These parts are essential to the valve’s application. The ANSI ball valve has an end fitting material which is mainly stainless steel. The cover could also be present in carbon steel, aluminum or even bronze. The valves are in split body design. Other parts include the seal and the seats. They feature RTFE material that has a viton O-ring body.

It is the work of the seat to provide the essentially required downstream as well as the upstream seal and also the in-line wear that is adjustable. It has the stem which has a RTFE material fitted. The handle of the valve is stainless that may or may not contain a pad locking device. This is the device which allows the locking of the valve irrespective of its open or closed positions. The valve has stainless steel nuts and body bolts. The material is rated to work at a maximum of 150 PSI. The ANSI ball valves are non-fire safe unless otherwise specified. They can be automated at one’s wish.

Maintaining ANSI ball valves

It is necessary that one keeps on a regular checkup on the valves to ensure they are working correctly. All parts must be repaired and replaced correctly upon necessary requirements. Spare parts should be ordered correctly considering their size, rating and functions. All valves must be kept clean of unwanted materials. This will help in achieving the right effectiveness as well as lifespan of the ANSI ball valve. All manufacturers’ recommendations should be followed and abided while repairing or replacing the various parts of the valve. Ensure all relevant piping system details are considered while selecting and maintaining the ball valves. The models in the market today are numerous with different manufacturers offering different specifications to their ball valve models.
