EN 14433:2006 (E) 3 Foreword This European Standard (EN 14433:2006) has been prepared by Technical Committee CEN/TC 296 “Tanks for transport of dangerous goods”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2006, and conflicting national standards shall be withdrawn at the latest by October 2006. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
EN 14433:2006 (E) 4 1 Scope This European Standard specifies the requirements for footvalves for use on transportable tanks with a minimum working pressure greater than 50 kPa for the transport of dangerous goods by road and rail. It is applicable to equipment for use on tanks with gravity and/or pressure bottom loading and discharge. 2 Normative references The following referenced documents are indispensable for the application of this European Standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 12266-1:2003, Industrial valves - Testing of valves - Part 1: Pressure tests, test procedures and acceptance criteria - Mandatory requirements EN 12266-2:2002, Industrial valves - Testing of valves - Part 2: Tests, test procedures and acceptance criteria - Supplementary requirements EN ISO 6708, Pipework components - Definition and selection of DN (nominal size) (ISO 6708:1995) 3 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply. 3.1 maximum working pressure MWP maximum pressure up to which the valve can be operated 3.2 nominal size designated size of valve as defined in EN ISO 6708 4 Function The footvalve is a primary valve located in the lower part of the tank to ensure that escape of product from the tank is prevented. 5 Design and materials 5.1 General The footvalve shall be designed for a working pressure of at least 300 kPa. The footvalve shall normally be a non-pressure balanced design. If the valve is a pressure balanced design, a surge pressure of 5 times the MWP shall not jeopardize the tightness of the housing or the function of the valve. The manufacturer shall specify in drawings and other papers, the design and the materials of the footvalve. The valve specification shall include information regarding mating tank flange details.
EN 14433:2006 (E) 5 5.2 Design 5.2.1 The valve shall provide a closure located within the envelope of the tank. 5.2.2 The valve closure shall be positioned so that the pressure in the tank acts to increase the force on the valve seat, and shall be so designed as to prevent self-opening of the valve. 5.2.3 The opening of the valve shall be such as to give a minimum flow path through the valve of a diameter equal to the DN designation of the valve. 5.2.4 The operating mechanism shall be protected from inadvertent operation in transit either by a latching device or by locating within an enclosure. 5.2.5 As a minimum, each valve shall be marked with the direction of opening of the operating mechanism. 5.2.6 The external valve casing shall have a weakened section (e.g. a shear groove in the external casing or other appropriate means) so positioned that should the valve casing be removed by a severe impact, the sealing ca
