The Válvulas They are one of the most used equipment within the different industries, but for their correct use, the desired use and the type of corrosive fluids must be known. For which the SIESA Engineer must consider different factors to determine the ideal valve for their processes. The valves are the ones that regulate the corrosive flow according to the production process.
In day-to-day operations within a plant, you have a long list of concerns, such as meeting production schedules, maintaining product quality, and improving production efficiency. With SIESA fluoropolymer-coated valves, the last thing you need to worry about is the operation of your plant's control valves. Control valves respond to a process of circulating liquids, such as gas, steam, water, or chemicals to compensate for load disturbances and keep the regulated process variable as close as possible to the desired set point (cent point).
SIESA has a wide variety of valves coated with fluoropolymers such as PFA, PTFE and ETFE, which will adapt to any need you may have, so you can find:
Valve types
-
- Gate valve. Focused on the flow closure service, having a linear flow and producing a lower pressure drop in the system, compared to other types of valves.
-
- Male valve. Like the gate valve, they are designed for passage or closure and their components are body, male (piloncillo) and cover; providing a linear flow.
-
- Ball valve. Variant of the male valve, designed with a ball that has a hole in a geometric axis to connect the inlet and outlet of the body, allowing the passage to be opened and closed.
-
- Globe valve. They are used for applications with flow regulation and control; The pressure drop tends to be large.
-
- Butterfly valve. Suitable for passing and closing services; They provide low loss due to liquid friction and are fast in terms of turning.
-
- Diaphragm valve. They have the function of closing or opening a flow. They also function to regulate these flows as needed by the piping system.
-
- Retention or Check Valve. It prevents reverse flow in the pipes, through automatic-mechanical operation that keeps them open under the pressure of the circulating fluid. There are ball types and swing types.
The choice of these valves should be taken based on the service that is needed:
-
- Regulation service (Globe, butterfly, diaphragm, compression valves)
-
- Closing and opening service (gate, plug or ball valves)
-
- Backflow Prevention (Check Valves)
SIESA solution
the body of the SIESA valves with carbon steel body, stainless steel and special alloys coated with Fluoropolymers PTFE (polytetrafluoroethylene), PFA (Polytetrafluoroethylene) and ETFE (Ethylene-Tetrafluoroethylene) are highly resistant to corrosion both on the outside and inside to resist attack by acids, alkalis and saline environment. The valve body meets ANSI B16.10 dimensions and the flanges are in accordance with ASME B16.5.
The correct selection of the valve for your processes will allow you to optimize them and subsequently save wasted money and time, with a useful life from 30 to 40 years.
