European EN Standards

EN 14341 is the European standard specifying the design, manufacturing, material, testing and inspection requirements for steel check valves used in industrial applications. The standard applies to forged, cast and fabricated steel check valves installed in steam systems, water networks, process plants, power stations and petrochemical facilities.

EN 13774 is the European standard specifying performance requirements for metallic isolating valves used in gas distribution systems with a maximum operating pressure of 16 bar. The standard applies to valves operating with fuel gases of the first, second and third family in accordance with EN 437 and provides additional requirements to relevant valve product standards.

EN 13709 is the primary European standard covering steel globe valves and globe stop-check valves used in industrial process systems, steam networks, power generation facilities, chemical plants and petrochemical installations. The standard specifies requirements for design, materials, dimensions, testing and operational performance of wrought, cast or fabricated steel valves in straight, angle and oblique pattern configurations.

EN 593 is the European standard specifying design, manufacturing, inspection, testing and performance requirements for industrial butterfly valves. The standard establishes common engineering requirements to ensure safe operation, pressure integrity and reliable performance in industrial piping systems. Butterfly valves manufactured according to EN 593 are widely used in water treatment plants, district heating networks, HVAC systems, power generation facilities, marine applications,...

EN 1983 is the European standard that specifies the design, manufacturing, inspection, testing and performance requirements for industrial steel ball valves. The standard establishes requirements intended to ensure safe operation, pressure integrity and reliable shut-off performance in industrial piping systems. Steel ball valves manufactured according to EN 1983 are widely used in steam systems, power generation facilities, chemical plants, petrochemical installations, district heating...

EN 1349 is the primary European standard for industrial process control valves. It specifies design, manufacturing, pressure-retaining, testing and performance requirements for valves used to control flow, pressure, temperature and level in industrial process systems.

EN 12569 is the European standard that establishes standardized terminology for industrial valves. The objective of the standard is to provide a common technical language for manufacturers, engineers, inspectors, contractors, suppliers and end users involved in the specification, design, operation and maintenance of industrial valve systems.

EN 12516 is the primary European standard governing the strength design of industrial valves. It defines pressure-temperature ratings, wall thickness calculations, allowable stresses and design requirements for valves operating under pressure.

EN 12266 is the primary European standard defining pressure testing, tightness testing and acceptance criteria for industrial valves. The standard establishes uniform testing procedures used by manufacturers, inspectors and end users to verify the mechanical strength and sealing performance of industrial valves before delivery and commissioning.

EN 1092-1 is a European standard for circular steel flanges used with pipes, valves, fittings and accessories in PN-designated piping systems. It specifies flange types, dimensions, sealing faces, tolerances, bolting, materials, marking and pressure/temperature ratings. For industrial valves, EN 1092-1 is essential for correct mechanical connection between the valve and the pipeline. Matching only DN or PN is not enough. Bolt hole pattern, sealing face, flange type and compatibility with the...

EN 558 specifies the face-to-face and centre-to-face dimensions of metallic industrial valves installed in flanged piping systems. It is an important standard for valve selection, replacement and installation because it helps confirm that the valve has the correct installation length. EN 558 is used for PN and Class designated valves and is especially useful when a valve must be replaced without modifying the existing pipework.

EN 10204 is the European standard that defines the different types of inspection documents supplied with metallic products, industrial valves, steam traps, piping components, pressure vessels and process equipment. The standard specifies how manufacturers document conformity with applicable material specifications, manufacturing standards and project requirements. EN 10204 does not define material properties. Instead, it defines how inspection and testing results are documented and...
