What is BS EN 60534-2-4 - Industrial-process control valves flow capacity about?
BS EN 60534-2-4 is a British standard as part of the IEC 60534 series that applies to all types of industrial-process control valves. BS EN 60534-2-4 defines how to state typical control valve inherent flow characteristics and inherent rangeabilities.
BS EN 60534-2-4 also defines how to establish criteria for adherence to manufacturer-stated flow characteristics.
Who is BS EN 60534-2-4 - Industrial-process control valves flow capacity for?
BS EN 60534-2-4 on industrial-process control valves flow capacity is useful for:
- The oil and gas industry
- The food and beverages industry
- The pharmaceutical industry
- The marine industry
- Valve manufacturers
Why should you use BS EN 60534-2-4 - Industrial-process control valves flow capacity?
The stated inherent rangeability of a specific control valve is related solely to the interaction between the closure member and the flow control orifice of a valve. This given value may not be applicable when the control valve is installed. Other factors such as the positioning accuracy of the actuator or the effects of hydraulic flow resistance of associated piping should be considered when deriving the installed rangeability for a specific application. The typical inherent flow characteristics and the values of n, m and Φ0 for a specific size, type and trim configuration of a control valve shall be stated by the manufacturer either graphically or in tabular form. It's the ratio of maximum to minimum regulated flow rates.
BS EN 60534-2-4 provides you with the typical inherent flow characteristics, inherent rangeability and the permissible deviations between actual and manufacturer-stated inherent flow characteristics. Using BS EN 60534-2-4 guidelines enhances process control and working range and ensures safety, protection, durability and high quality equipment for its users.
