Full Valve Size Chart List for Your Right Valve Dimension – XHVAL

Regardless of the type of valve, ensuring that you purchase the right size and dimension is necessary to guarantee flow efficiency in your application. The size affects the amount of pressure the valve can support, which may affect the flow rate and control in turn. Finding the right size can save you costs and earn you good returns on investment. 

Valve Sizing

A general practice to determine the correct valve size is to use the equation Q = Cv√(ΔP/G), where Q is the capacity in gallons per minute, Cv is the valve flow coefficient, ΔP is the pressure differential in pound per square inch, and G is the specific gravity of the fluid. 

Manufacturers typically have a list of valve flow coefficients for all the models and dimensions of their industrial valves. By finding the Cv required for your application, you can choose a suitable valve size. 

Valve Codes and Standards

DIN valve standards

DIN valve standards, set by the Deutsches Institut für Normung, are more commonly known as German valve standards. Common standards include DIN EN 488, DIN EN, and more, varying depending on the application type.

BS valve standards

BS valve standards are set by the British Standards Institution, the national standards authority of the United Kingdom. Types include BS 1212 for ball valves, BS 1414 for gate valves, and others.

ISO valve standards

ISO valve standards, published by the International Organization for Standardization, define the qualifications required for designs, functionality, and other aspects of industrial valves. 

ASME valve standards

ASME valve standards are set and regulated by the American Society of Mechanical Engineers. These standards may detail the pressure and temperature ratings of certified industrial valves.

What is a standard ball valve size? Depending on the valve class you select, the ball valve standard dimensions will vary. For example, valve diameters may go from 15 to 600 millimeters (mm) for those categorized under Class 150. 

If you’re asking the question “How do I know what ball valve size I need?”, referring to the size of your hose or pipe is one way to do it. For instance, a two-inch ball valve may be suitable for a two-inch hose. But this may not be true for reduced bore ball valve dimensions. 

On how to measure ball valve sizes, you should consider measuring their diameters. Usually, markings like DNXX can be found on the valves. DN stands for nominal diameter, followed by the valve’s diameter size in mm.

Check valves do come in varying configurations, so selecting one that fits your application matters. But what size check valve do I need? To measure the ideal one with the check valve sizing calculation, you must know the floor velocity needed to lift its disc. After this, determine the average flow velocity in your pipes, ensuring that it’s either higher or equivalent to the minimum velocity of the valve.
