4 Tips to Select the Best BS5156 Diaphragm Valve

Consider the Application Requirements

Before selecting a BS5156 diaphragm valve, it's essential to understand the specific requirements of your application. Here are the key factors to evaluate:

• Medium: Determine the type of fluid being handled—liquid, gas, corrosive, or abrasive substances require different valve materials and designs.
• Pressure and Temperature: Assess the operating pressure and temperature limits to ensure the valve can withstand the conditions.
• Flow Rate: Calculate the required flow rate to select a valve that meets your system's demands.

Material Selection

Choosing the right materials for a diaphragm valve is crucial for performance and longevity. Follow these steps:

• Diaphragm Material: Common materials include EPDM, Neoprene, and PTFE. Select based on compatibility with the fluid and temperature resistance.
• Body Material: Options include PVC, stainless steel, or cast iron. Choose a material that offers durability and resistance to corrosion.

Actuation Type

BS5156 diaphragm valves can be manually or automatically actuated. Consider the following:

• Manual Actuation: Best for applications where infrequent operation is needed. Check if it offers ease of use and reliability.
• Automatic Actuation: Ideal for complex systems requiring remote control or integration with automated processes. Consider solenoid or pneumatic actuators based on system compatibility.

Budget and Maintenance

Finally, take into account the financial aspect and maintenance requirements:

• Cost: Compare prices among different manufacturers while ensuring you don’t compromise on quality. Sometimes, investing a bit more can save costs on repairs and maintenance in the long run.
• Maintenance: Consider the ease of maintenance and availability of replacement parts. A valve that requires less frequent maintenance may be more cost-effective over time.
