FAQs of Metal Diaphragm Valve:

Q: How does a metal diaphragm valve function in fluid control?

A: A metal diaphragm valve works by using a flexible diaphragm that moves up and down to regulate, start, or stop the flow of various fluids. This mechanism ensures tight shutoff and prevents leakage, especially with corrosive or hazardous fluids.

Q: What types of media can be managed with this valve?

A: This valve is designed to handle water, gases, oils, chemicals, and aggressive or corrosive fluids, making it ideal for diverse industrial applications such as chemical processing, water treatment, food processing, and pharmaceuticals.

Q: When is it best to use a metal diaphragm valve over other types?

A: Metal diaphragm valves are recommended when your application involves corrosive, abrasive, or high-purity fluids at pressures up to 16 bar and temperatures up to 180C. Their design helps minimize contamination and ensures reliable sealing.

Q: Where can these valves be installed?

A: These valves can be installed in pipelines of industrial plants requiring precise control, such as in chemical manufacturing, water and wastewater treatment facilities, food processing units, and pharmaceutical operations.

Q: What is the benefit of choosing a cast iron or stainless steel valve body?

A: Cast iron provides excellent strength and cost efficiency for general use, while stainless steel offers superior corrosion resistance, making it suitable for harsh chemicals and highly corrosive environments.

Q: How are the valves connected to piping systems?

A: Depending on process requirements, these diaphragm valves can be connected using flanged, screwed, or socket weld fittings, providing installation flexibility for different pipeline standards and layouts.

Q: What is the process for selecting the right valve size and configuration?

A: Evaluate your systems flow rate, pressure, temperature, and type of media to determine the most suitable size (from 1/2" to 6") and material. Consult the manufacturer or supplier to customize the valve or choose from standard options to ensure reliable operation and compatibility.
