You want good results when picking the right valve for your system. First, look at these seven important tips. Think about what your system needs. Check if the materials and media work well together. Pick the right size for the valve. Look at how the flow works. Choose actuators and controls you can trust. Make sure everything is safe and follows the rules. Plan for how you will take care of and fix the valve. Sunlike Machinery has worldwide experience and ISO certifications. They give strong solutions for every high temperature electric shutter valve project. Use the STAMPED method to fit your needs and stop common mistakes.
Key Takeaways
-
Know your system’s temperature and pressure needs before picking a valve.
-
Pick materials that can handle heat and do not rust. This helps the valve last longer.
-
Choose the right valve size to help flow and stop leaks or wasted energy.
-
Use good actuators and controls so the valve works well every time.
-
Make sure the valve is safe and has the right certificates to follow rules.
Assess Application Requirements
Temperature Range for High Temperature Electric Shutter Valve
Before you pick a high temperature electric shutter valve, you must know the temperature your system will face. The STAMPED method helps you look at the right things. First, check the highest and lowest temperatures in your process. Some valves have special O-rings for very hot conditions. FKM O-rings can handle up to 150º C. FFKM O-rings can go up to 180º C. Here is a simple table:
O-ring Type
Maximum Temperature Rating
FKM
150º C
FFKM
180º C
Choose a valve that fits your system’s temperature range. Sunlike Machinery has worked on many high temperature projects. They have experience in cement, metallurgy, and environmental protection. Their valves work well in hard conditions and help stop failures. If your process needs high vacuum suitable valves, make sure the valve can seal tightly at high heat.
Tip: Always check the temperature rating for every valve part. Seals and actuators must also handle the heat.
Pressure Ratings and System Demands
Pressure is also very important when picking a high temperature electric shutter valve. You need to know the highest and lowest pressures in your system. The STAMPED method helps you match the valve’s pressure rating to your needs. Sunlike Machinery makes valves for high vacuum suitable and high-pressure systems. Their products meet ISO9001:2015 standards, so they are reliable.
Look at the valve’s pressure rating on the technical sheet. Make sure it matches your system’s needs. If you use the valve in high vacuum suitable processes, pick models with strong seals and bodies. Sunlike Machinery’s valves work in many tough places around the world. You can trust their knowledge to help you pick the right valve.
Material and Media Compatibility
Choosing the Right Valve Materials
You must pick materials that can handle heat and tough fluids. Valves are made from different metals and alloys. Stainless steel is good for many hot jobs. It does not rust and can take heat up to 800 °C. Nickel-based superalloys work even better in very hot and harsh places. These alloys can stand heat up to 1093 °C. Some valves use titanium alloys for extra strength when it gets really hot.
Tip: Always look at the pressure-temperature ratings for each valve. Make sure the material fits your system’s needs. Sunlike Machinery uses strong materials to meet ISO9001:2015 standards. Their worldwide experience helps you pick the best valve for your project.
Media and Corrosion Resistance
Process fluids can hurt a valve if you choose the wrong material. You need to see how the fluid touches the valve body and seals. Some valves use all-stainless steel bodies to fight rust. Nickel-based alloys also stand up to harsh chemicals. You must think about steady and changing heat to stop early damage.
Sealing choices help stop leaks. Here is a table with common sealing options for high temperature electric shutter valves:
Feature
Description
Valve Type
77.3 UHV Fast Closing Shutter
Design
Slot shutter valve (DN 40 – 160)
Bake Out Temperature
Max. 300°C for valve body, max. 50°C for actuator
Seal Type
Metal sealed with welded metal bellows for feedthrough
Feature
Description
Valve Type
Series 590 All-Metal Leak Valve
Body Material
All-stainless steel
Seal Type
All-metal seal ensuring durability in UHV and XHV environments
Lifespan
400,000 control life cycles and 10,000 leak-tight closing cycles
You should look for common reasons why valves leak. Worn valve stem packing often causes leaks. Heat, pressure, and harsh fluids make wear happen faster. Good installation and regular checks help stop leaks. Sunlike Machinery makes valves with strong seals and tough materials. Their products help you avoid leaks and keep your system safe.
Valve Sizing and Flow

How to Choose a Valve Size
Picking the right size valve is very important. If the valve is too small, it might leak or break. If the valve is too big, it can waste energy. It can also make your system work poorly. Sunlike Machinery says to use the STAMPED method. You should think about a few key things before you choose. Here is a table that shows what to check:
Factor
Description
Pressure
Needed to stop leaks or breaks if too small, or bad use if too big.
Operating Temperature
Know the highest and lowest temperatures for picking materials and design.
Operating Pressure
The pressure the fluid has when moving through the valve.
Fluid Flow Rate
Helps you pick a valve that can control how much fluid moves.
Nominal Diameter (DN)
Stops problems from picking a valve that is too big or too small.
Always look at the technical sheet for each valve. Sunlike Machinery’s valves meet ISO9001:2015 standards. You can trust their sizing information. Their worldwide experience helps you avoid mistakes.
Tip: Measure your system’s flow rate and pressure first. This helps you pick the right valve for your needs.
Flow Characteristics for Optimal Performance
How the valve handles flow is very important. You want a valve that controls flow well. It should not cause big drops in pressure or make the fluid move roughly. Sunlike Machinery makes valves for smooth and steady flow. Their engineers use special tools to test how the fluid moves.
Look for valves with features that fit your flow needs. Some valves have special shapes or guides inside to help control flow. If you use high temperature or high vacuum systems, pick a valve with a strong seal. The valve body should also handle heat and pressure. Sunlike Machinery’s valves work well in hard places. They help you get good and safe results.
If you want to pick a valve for your system, always think about flow rate, pressure, and temperature. These things help you choose the best valve for safety and good work.
