Introduction Butterfly valves help control fluid flow in many industries. Choosing the right one is key for efficiency and reliability. Let’s dive into how to pick the best butterfly valve.
PICKING A VALVE TYPE: HANDLE VS. TURBINE :
- Small pipes (up to DN 100 mm)? Use handle butterfly valves. They’re straightforward and affordable.
- Big pipes (DN 100 mm or larger) needing precise control? Turbine butterfly valves are the way to go.
- Reflect on your needs, level of control, and budget.
FLANGE OR WAFER BUTTERFLY VALVES :
- Wafer butterfly valves: Compact, budget-friendly, and great for pipes up to DN300 under 16 Bar pressure.
- Flange butterfly valves: Strong and perfect for larger pipes beyond DN300.
- Consider the pipeline’s heat-related expansion and installation methods.
CHOOSING THE MATERIAL: HARD SEAL VS. SOFT SEAL :
- Hard seal valves: Made of metal, suitable for high temperatures, high pressure, and harsh conditions.
- Soft seal valves: A blend of metal and non-metal. They ensure a good seal and are affordable for standard uses.
- Evaluate the fluid’s nature, its temperature, and pressure.
FOLLOW INDUSTRY STANDARDS :
- Stay in line with industry standards and heed the manufacturer’s advice when picking and setting up your valve.
- Ensure the valve’s material is resistant to corrosion from your fluid.
GETTING THE SIZE AND FLOW RIGHT :
- Ensure the valve’s size aligns with your flow requirements.
- Examine the valve’s Cv value. It indicates its flow capability at varying pressures.
HOW TO OPERATE: MANUAL OR MOTOR-OPERATED :
- Manual valves: Simple and cost-effective, ideal for less complex systems.
- Motor-operated valves: Automated, making them suitable for larger or intricate systems.
Selecting the ideal butterfly valve is vital. Factor in the valve type, material, operation method, and industry norms. And always seek guidance from valve manufacturers or experts in the field.
