What is BS EN 14433 - Foot valves about?
BS EN 14433 is a European standard that specifies the requirements for foot valves for use on transportable tanks with minimum working pressure greater than 50 kPa for the transport of dangerous goods by road and rail.
BS EN 14433 is applicable to metallic equipment for use on tanks with gravity and/or pressure bottom loading and discharge for liquid chemicals and liquefied gases. BS EN 14433 includes carbon dioxide while excluding refrigerated liquefied gases.
Note: BS EN 14433 is also applicable to liquefied gases including LPG, however, for a dedicated LPG standard see EN 13175.

Why should you use BS EN 14433 - Foot valves?
The foot valve protects the pump from dry runs caused by fluid or gas backflow from the pipe. The foot valve is a check valve that permits unidirectional substance passage in the pipe while maintaining the pump prime and preventing damage. In a suction lift application, the foot valve is normally located at the bottom of the pipeline.
BS EN 14433 guidelines provide its users with design, materials, and test methods for performance and efficiency. Using BS EN 14433 guidelines ensures safety, high quality, reliable and durable equipment for longer service life and also aids in energy and time conservation.
