What is a metal seated ball valve?
by Yunus Shaikh B Tech in Mechanical Engineering with knowledge in
A ball valve manufacturer makes a metal-seated ball valve with a metal-to-metal seal between the ball and the seat. Ball valves with metal seated seats can be used in applications involving corrosion, abrasion, high pressure, or high temperatures. In severe applications, metal seated ball valves offer tight shutoff in both bidirectional and unidirectional fluid flow. Ball valves with metal seats can be made harder by coating them with ultrasonic spray coatings, chromium carbide, satellite hard facing, and tungsten carbide, for example. Valve seats on metal seated ball valves are made from metallic materials such as stainless steel 316 or model. A ball valve with a soft seat is usually made of PTFE, which allows it to serve in a clean manner only, as opposed to one with a metal seat. In severe service applications, metal seated ball valves have proven to be one of the best solutions. Ball valves with metal seats each have their own characteristics, which result in unique advantages and disadvantages.
Advantages of Metal Seated Ball Valve
Ball valves with metal seated seats operate quickly.
It is difficult for abrasion wear to damage metal seated ball valves.
Corrosion resistance is a feature of these valves.
Ball valves with metal seated seats are highly durable for high-pressure and high-temperature applications.
They last for a long time because metal seated ball valves can be repaired, cleaned, and inspected.
In addition to their versatility, metal seated ball valves can be used in a variety of industries and for a variety of purposes.
A metal seated ball valve has tight seals that prevent leakage.
Drawbacks of metal seated ball valve
Ball valves with metal seated seats are more expensive than ball valves without metal seated seats.
When slurry solidifies or blocks cavities around metal seated ball valves, they become difficult to open and close.
Metal seated ball valves require vertical installation of the drive mechanism.
Where to use a metal seated ball valve
In various applications such as steam power plants, oil and gas, food and beverages, pharmaceuticals, agriculture, and water supply, metal seated ball valves are used like
Acidic products are transferred using metal seated ball valves.
In the oil and gas industry, these valves are used.
Ball valves with metal seats are used in steam power plants.
The valves are also used to transfer fluids with slurries.
These valves are most commonly found in the food and beverage industry.
They are also used in the pharmaceutical industry.
Petroleum industries use metal seated ball valves.
