Description

Technical Parameters

A diaphragm valve is a unique type of valve that functions as a shut-off valve. It exhibits bi-directional flow capability. The diaphragm, which acts as the opening and closing element in this valve, is constructed from a soft, elastic, and non-corrosive material such as rubber or plastic. This diaphragm effectively separates the fluid within the valve body cavity from the cover cavity and the driving member. As a result, it prevents the contamination of the working medium and the corrosion of the operating parts.

This device is specifically designed for the regulation of both non-corrosive and highly corrosive substances. Its internal structure is either unlined or lined with various types of fluorine plastics, allowing it to be customized based on the specific temperature and fluid requirements of different pipelines. The appropriate working temperature is determined by the choice of lining material and diaphragm.

Standard compliance

1.Design and manufacture: API6D, BS5156

2.Test and inspection: API598

3.Face to face dimensions: API6D,BS5156

The available flanged end options include ANSI B16.5, BS4504, DIN2532, JIS B2212, and ISO2004. These standards ensure that the flanges are compatible with various piping systems and fittings. Choosing the appropriate flanged end for your application is crucial to ensure a secure and reliable connection between the pipe and the fitting. It is recommended to consult with industry experts or refer to the relevant standards before making a selection.

The standard materials used for the parts of a weir pattern diaphragm valve are typically as follows:

No.	Part	Material
1	Body	Carbon steel with PFA or F46, cast iron, and ductile iron are materials commonly used in various industries. These materials possess unique properties that make them suitable for different applications. Cast iron is a type of iron-carbon alloy that contains a high percentage of carbon. It is known for its excellent heat retention and heat distribution properties. Cast iron is often used in the manufacturing of cooking equipment, such as frying pans and Dutch ovens, due to its ability to distribute heat evenly. Ductile iron, also known as nodular iron, is a type of cast iron that contains nodules of graphite. These graphite nodules give ductile iron its distinctive ductility, making it more flexible and less brittle than traditional cast iron. Ductile iron is widely used in applications that require high strength and toughness, such as automotive parts and pipes. Carbon steel with PFA or F46 coating is a type of carbon steel that has been treated with a PFA (perfluoroalkoxy) or F46 (tetrafluoroethylene-perfluoroalkylvinylether copolymer) coating. This coating provides excellent chemical resistance and non-stick properties to the carbon steel, making it suitable for applications in harsh chemical environments. Carbon steel with PFA or F46 coating is commonly used in the chemical processing industry for the manufacturing of tanks, valves, and pipes. In conclusion, cast iron, ductile iron, and carbon steel with PFA or F46 coating are versatile materials that offer unique properties suitable for various industrial applications. These materials play a crucial role in industries such as cooking, automotive, and chemical processing.
