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.
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 The internal stop-valve of all filling and all discharge openings of tanks (for tank containers with a
3
capacity greater than 1 m ) intended for the carriage of liquefied flammable or toxic gases shall be instant-
closing and shall close automatically in the event of an unintended movement of the tank or in the event of fire.
It shall also be possible to operate the internal stop-valve by remote control.
5.2.6 As a minimum, each valve shall be marked with the direction of opening of the operating mechanism.
5.2.7 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 capability of the valve shall not be affected. This requires that, in the case of a bottom-operated valve,
the operating mechanism of the valve be not directly connected to the valve closure.
5.2.8 Regarding the calculation of flanges and body wall thickness the requirements given in EN 12516-1 to
EN 12516-3 or EN 13445 apply.
5.3 Materials
5.3.1 The manufacturer shall provide, with the equipment, the material specification for those parts that may
come into contact with the product.
5.3.2 The material elongation at fracture of the pressure-loaded components of the valve shall be a
minimum of 12 %.
5.3.3 The relevant EN reference, where possible, for the valve casing material shall be permanently marked
on the valve casing. Should no EN exist then the appropriate national standard designation may be used.
