Comparison of Metal Seat Ball Valves and Soft Seat Valves

Metal seat valves excel in the harshest manufacturing indoor environments, and valve shortcomings can seriously compromise safety, compromise high efficiency, and reduce gross profit margins. This durable metal seat valve is especially suitable for crude oil and natural gas, oil refineries and power utilities.
So what are the advantages of metal seat ball valves? Raffles Shield Valve briefly explains it for you:
Metal seated and soft seated valves.
For ball valves, choosing the right seat material can be a difficult decision because you will have many choices. Key factors that must be considered when identifying elements include raw materials used in home construction, modest specifications and types of design features, including V-port numbers, exhaust pipes, dual bases, 1.2 or 3 pieces, etc., but more must be carefully considered. One of the reasons is the type of seating.
First of all, you need to fully grasp the whole process and standard of valve application, which should be the basis for valve seat selection. Do you need to turn off the styrofoam in the valve? Is the liquid corrosive? Does it include abrasive particles? Is it under high pressure or constant heat? Once this element is firmly grasped, the choice is self-evident.
Metal Seat Ball Valve
Compared with the soft seat valve, the specific feature of the metal seat valve is that it can withstand high temperature and severe operating standards. Metal seats tolerate extreme moisture, hydraulic shock, abrasive slurries and high temperatures up to 1000°F. They are also a satisfactory choice for highly corrosive or corrosive applications. Another major element is that the metal seat can be hardened according to a special coating.
Soft Seat Ball Valve
Soft seats are usually made of thermoset components such as PTFE. This valve is suitable for places where organic chemical compatibility and sealing are required. As everyone knows, the soft seat does not feel comfortable to solve corrosive or dirty liquids. In such a case, the valve can crack, causing the valve to leak. The complexity of soft-seat valves is related to the objective fact that they cannot afford extreme use. On the other hand, metal seated valves can maintain normal operation in high temperature and extreme applications. Metal-seated ball valves are widely available for maximum shut-off specification and ongoing service. Compared to soft valves, this valve operates longer. This durable valve can usually handle most grinding applications.
Metal seat plating.
For metal-to-metal seats, rubbing a variety of coatings can make the ball and seat ring harder and more resistant to wear in the sealing area, depending on the application standard. This unique coating includes synthetic hard surface coatings, carburized chromium, cobalt alloys and electrolytic nickel. Sealability based on metal contact between 2 hard-coated surface areas.
The cost of the metal seat valve.
Although the price of metal seat valves is relatively high, the use of soft seat valves should also take into account the damage caused by common failures and the cost of replacing soft seat valves. Compared with the service life, the high efficiency of the metal seat valve is more cost-effective. Metal-seated ball valves are the best, long-term, and economical choice for important applications.
