FAQs of Diaphragm Non Return Valves:

Q: How should a Diaphragm Non Return Valve be installed for optimal performance?

A: For best results, the valve can be mounted either horizontally or vertically, depending on the flow direction and space constraints. Always follow the flow direction indicated on the valve body, and refer to installation guidelines specific to the end connection standard used in your system.

Q: What are the primary benefits of using Diaphragm Non Return Valves in industrial processes?

A: These valves provide zero leakage (Class VI/API 598), corrosion resistance, and are suitable for aggressive media. They also feature robust operation with customizable materials, making them ideal for minimizing downtime and maintaining process integrity in demanding environments.

Q: When should I choose PTFE or Viton diaphragms for my application?

A: Select PTFE or Viton diaphragms when handling highly corrosive chemicals, elevated temperatures (up to 80C), or where compatibility with aggressive media is essential. Both materials offer excellent chemical resistance and extended service life compared to standard elastomers.

Q: Where can Diaphragm Non Return Valves be utilized effectively?

A: They are highly effective in water treatment plants, chemical industries, HVAC systems, and general process plantsanywhere reliable backflow prevention and chemical compatibility is required. Their flexible design supports both new installations and retrofits in existing pipelines.

Q: What installation process is recommended for these valves regarding pressure standards?

A: Install the valve following the relevant hydrostatic and shell test pressures as per ANSI, DIN, or ISI standards. Ensure face-to-face dimensions comply with ASME B16.10 or DIN EN 558 to guarantee proper integration with adjacent pipeline components.

Q: How do I determine the correct port size and valve material for my system?

A: Port size selection should correspond to your pipelines nominal diameter, ranging from 15 mm to 300 mm ( to 12). Material choice depends on application media and environmental conditions; refer to the datasheet for guidance on weight and temperature limits for cast iron, stainless steel, or PVC options.
