Industry Spotlight: Valves
Thermal spraying is often used to overcome the limitations of standard surface protecting processes. At A&A Coatings, we have the capability to produce thermal spray coatings that suit cross-industry applications. What’s more, they can enhance the wear and corrosion resistance properties of a wide range of industrial components, including valves. The seamless performance of valves is critical to the success of various industrial processes and that’s why we offer a range of solutions that protect vulnerable parts from corrosion and wear.
What A&A Coatings Offers for the Valve Industry
For starters, we offer an extensive selection of hard coating solutions for the valve industry. You can rest assured that we carefully select our coating materials; they are integral to the valve design process itself. If we need to hard coat a valve for the chemical processing sector, we use cermet and ceramic materials such as chromium oxide. If we need to coat valves that are used in the oil and gas sectors, we will use tungsten carbide.
We also provide metal-to-metal coating solutions that suit ball and gate valve applications in the petrochemical industry. When it comes to fluid handling, our specialized HVOF coatings ensure that each valve are kept tight. With our coating solutions, solids and scaling that can cause erratic jamming problems in valves are no longer an issue.
Common Valve Applications
Industrial valves play a large role in a great number of industries. Whether they are used in the gasoline mechanisms of automobiles or water/HVAC systems in an office, well-coated valves are an essential piece to the puzzle. To help you understand better about the role valves play in proper operation, below are a few examples:
- Marine applications
Valves are widely used in the marine industry. They are used to regulate the storage and loading of a ship’s power supply, handle and process wastewater, provide water for fire-fighting capabilities, store liquid cargo and more.
- Biopharm applications
One major feature of valves used in the biopharm industry is their ability to be cleaned, sterilized, and be able to tolerate the nature of the media. High quality valves are also needed to offer high leakage protection and precise flow control. This way cross-contamination and spills do not occur.
Our Expertise in Thermal Spraying Valve Balls
Since our inception, we have also developed a process for thermal spraying PTFEs, metals, carbides and ceramics onto valve balls. You can be sure that they have a perfect mechanical fit that is suited for most demanding pressures. We utilize a 6-Axis Robot to apply our coatings to the metal substrate. Below is quick look at the basic properties of our valve ball coatings:
- Lower maintenance and operating costs
- Enhanced mobility without the need for ball scoring
- Increased valve body and valve ball service lifespan
- Parts that have corroded, pitted and worn can be salvaged
- Reduced activity in systemic galvanic cell
- Anti-fouling
- Have abrasion resistance
- Low coefficient of friction
