Metal seated ball valve is a valve that has a ball-shaped seat. The valve has a long stem with two or more opening ports.This valve with flanged end can be used in different applications, such as gas, water, steam, oil and gas pipelines.
These valves allow for quick and efficient fluid transfer. They are commonly used in many industries such as oil, gas, mining, chemical supply and pharmaceuticals.Metal seated ball valves are type of valves with a rounded or spherical head that is designed to seal against an adjacent surface with the use of a seat (a round disk) or flange (a rectangular shape). The ball can be made out of carbon steel, forged steel, duplex steel, stainless steel or many other materials.
Seating of Metal Seated Ball Valves
Ewom recommends metal-sealed ball valves. It is a bi-directional valve of graphite solids proof gaskets between seats and valves. Ball and seat coatings protect against erosion and corrosion when cycling. The valve is optimized for high temperature in any high pressure situation.
Metal Seated Ball Valve Body Materials
Stainless steel( A351 CF8,A351 CF8M,A351 CF3,A351 CF3M,A351 CF8C)
Cast steel(A216 WCB)
Duplex Steel(A890 Gr 4A,5A,6A)
Special Alloy Available on client’s requirement.
These valves are available in a variety of configurations and sizes. This includes a two piece, three piece body design.
Side entry or Top Entry
Side entry or top enty is available on your project request.
When it comes to project requests, you need to choose between a side entry or a top entry. The benefit of a side-entry is that it allows you the option to reuse the track for future projects, without damaging it by removing and reinstalling it. A top-entry, however, allows for quick and easy installation and removal of the track.
Floating Type and Trunnion type
The valve is used for service and is normally open. The type is a available in two types: floating, trunnion mounted.
Advantage metal seated Ball valves
Metal seated valve is a type of valve that is designed to handle high temperature and severe service conditions. This type of valve is typically made of steel which helps it withstand high temperatures.
Most seats hardened by a coating so they don’t bend or break. Some common coatings include: ultrasonic spray coating, satellite hard facing, chromium carbide and tungsten carbide.
One of the most common types of valves that are used in a variety of industries is the metal seat ball valve. This type of valve is typically used for water distribution piping, irrigation systems, and fire protection sprinkler systems.
While this type of valve can be used in many different applications, it has several advantages which make it an attractive option for many types of high temperatures industries.
Metal seat ball valves are known to be durable and reliable because they come with a built-in self-lubricating mechanism that decreases the chances for leaks and corrosion. These disadvantages are offset by its low cost per unit and ease of installation.
Specifications of the design
The metal seated Valves provide excellent performance in high temperature, high pressure, corrosive, and aggressive media.
Design Standards: API 608, API 6D ASME B16.34 The Size Range: 1 /2″ to Pressure range: Class 150 to Class 2500. Flanged end dimensions: ASME B16.5 (24>) butt weld end dimensions: ASME B16.25;ASME B16.47 (approx. Series A or B (>24″) Dimensions face – face: ASME B16.10; Socket weld/butt weld socket : ASME B 16.11;Pressure and temp ratings ASME B16.34.
Inspection and testing Metal Seated Ball Valve
API 598 test without any leakage. API 598 is an American Petroleum Institute standard that specifies how valves are tested according to their function. The API 598 standard was developed to provide uniformity in the testing of valves by organizations performing quality assurance.
A ball valve for industrial use is a metal seated valve with a highly polished surface. It can be used in applications where the fluid pressure is high, and it can be used for the safe flow of abrasive fluids, high temperature process performance, steam or gas.
Which is the best process?
The upfront purchase price of a seat ball valve in metallic may be favorable to it. Should be thought about the cost of maintenance for soft seat valves. Understanding your application processing conditions is key. If the select is not clear speak to an engineer who is knowledgeable in valve selection as well. How do I order my seat? So you asked us!
