Difference Between Metal Seated Ball Valves vs Soft Seated Valves
Design the Gala Valves Suppliers in Pakistan most demanding industrial environments valves. Defective valves can be a safety issue. Gala Valves Suppliers in Pakistan are excellent, reducing the plant’s ability to increase efficiency gains. These long life valves are ideal for the oil and gas, refining and power generation industries. Here we are discuss about two types of Gala Valves, Metal seat valve and soft seat valve:
Metal Seat Valve and Soft Seat Valve
The Gala Valves Suppliers in Pakistan are determining the material of the right seat can be a difficult decision for a ball valve. Because you have many options. Factors to consider include the materials used in construction. Suitable size eg design feature type such as port, bleed, 1, 2, or 3 double squares.
A full understanding of process conditions should be the starting point when selecting a valve seat. Does your case require severe closure? Is the liquid corrosive? Does it contain corrosive particles? Will it be high pressure or high temperature? Once you have a solid understanding of these factors, your options will be clear.
Metal Ball Valve Seat
Metal shoulders can handle severe flashes. Fluid temperatures from the hydraulic shock wear process are in excess of 1,000 degrees Fahrenheit. It is also ideal for highly abrasive and abrasive applications. Another important factor is that metal upholstery can be treated with a special coating.
Soft Seat Ball Valve
Soft plates are usually composed of thermoplastic components such as PTFE. These valves are suitable for applications where chemical compatibility is important. Although sealing is essential, soft pads are not suitable for handling corrosive or soiled liquids. These valves are known to degrade under these conditions. Leaking valves Complications caused by soft seat valves relate to the valve’s inability to withstand applications that violate service limits. On the other hand, ball plate values can be stored at high temperatures and under harsh service conditions. Field-accepted metal ball valves provide continuous service with the highest shut-off standards. They also operate longer than soft seat valves. These robust valves can generally handle most corrosive applications.
Sheet Metal Coating Options
Metal-to-metal service and seating conditions follow the use of various coatings to strengthen the ball ring and seat surface in the stamped position. An example of such special coatings, depending on the conditions of use, is satellite treatment. Chromium carbide is nickel-electrolytic tungsten carbide. Sealing is achieved by metal-to-metal contact between two areas of a strongly painted surface.
Metal seat ball valve cost
Although metal seat valves are more expensive. However, the cost of downtime caused by the malfunction must also be considered, along with replacing a failed seat valve. Equalizes the performance and life expectancy of a metal seat ball valve and withstands high prices. Metal ball valves are ideal for critical applications, and an economical, long-term choice.
Installations
Metal seat valve fitting is designed to comply with shut-off standards, including ANSI/FCI 70–2–1976, and withstand allowable leaks. The most specific dropout classes are classes V and VI. The sixth category is often misunderstood as “narrow bubble”. Many leaks are tolerated. This was measured by the amount of air bubbles emitted per minute during the test. The ‘bubble-tight’ shutoff was more precisely connected to the resilient seat valve.
370 Series Metal Seat Valve
For metallic ball valves, the 370 series is a good example. This series is available in 1/4" to 4" sizes with threaded (NPT) or flange connections. Made of premium 316 stainless steel, this metal valve can handle pressures up to 2,000 psi. There is an ISO5211 mounting plate for custom work. You can choose from three types of configurations A, B, and C shown below.
Write A
This frame features traditional sheet metal. In addition to bar filling, Type A configurations are designed for use in high abrasive and high abrasion applications. Do not use high temperature
Write B
Downstream Use of Metal Pad This configuration is a sheet metal that combines a flexible graphite sheet sealing and rod sheathing. This configuration increases the temperature capacity of the metal ball valve.
Write C
Similar to Type B, Type C configurations use downstream sheet metal. Spring loaded to assist with initial padded downloads. This composition is suitable for hot gases and liquids. Type C configuration is suitable for 720PSIG saturated steam.
The 370 Series Metal Ball Valves Have The Following Features
- Available in flanged and threaded connectors sizes from 1/4 inch to 4 inch.
- For this configuration, the operating temperature limit is 450°F (232.2°C).
- The composition includes a metal plate with a stamping body. Polymer seat trunk filler
- SS316 Elastic Threaded / Graphite Seal Body (Flexible / Forged Graphite)
- Intended use is corrosive and/or corrosive use without high temperatures.
- The polymeric seals embedded in this sheet metal frame have been replaced by flexible graphite plate seals and stem sheathing.
It is important to consider the conditions of the process when choosing the right Valves for a particular application. If you decide that the best solution is a metal ball valve. Gala Valves Suppliers in Pakistan prove to be long lasting and cost effective for critical applications.
