They are classified A according to the sealing force requirements of 7.105. Balanced valves according to this standard are Class A valves. — Class D valves Valves which are not subject to the requirements for the sealing force and fixed closing time. SIST EN 16678:2016
Closed position indicator switch Closed position indicator switches, where fitted, shall not impair the correct operation of valves. Adjusters shall be sealed to indicate interference. Any drift of the switch and actuating mechanism from its setting shall not impair correct valve operation. 6.2.102 Valve with modulating control Flow rates of valves with modulating control shall be adjustable over the full range as stated in the installation and operating instructions. If the adjustment of one flow rate affects the setting of any other flow rate, this shall be clearly stated in the installation and operating instructions. The setting of any flow rate shall require the use of mechanical or electrical tools and shall be designed to discourage unauthorized adjustment. 6.2.103
Other controls assembled to a valve Other controls assembled to a valve shall not interfere with its shut-off function. 6.2.104 Balanced valves The closure member of a balanced valve shall have a resulting force in the closing direction where the sealing force is not decreased by the gas inlet pressure. For a balanced valve with one single valve seat a resulting force in the closing direction shall remain, if the balancing force is removed. The closure member shall have the same closing direction as the flow direction through the valve. 6.2.105 Additional requirements for shut-off function 6.2.105.1 Diaphragms that assist the shut-off function Shut-off functions using a diaphragm to apply (part of) the closing force to the closure member shall be designed in such a way that, when the diaphragm is damaged, the closure member closes and the maximum internal leakage rate of the valve is limited to 1 dm3/h. Conformity shall be verified by the method given in 6.2.105.2. 6.2.105.2 Leakage test Rupture the diaphragm assisting the shut-off function. De-energize the valve. Measure the internal leakage rate of the valve according to EN 161:2011+A3:2013, 7.3.3. SIST EN 16678:2016
Closure members Closure members of valves shall either have a mechanical support (e.g. metallic) to withstand the sealing force or shall be made of metal. 6.3.102
Parts transmitting the closing force Parts transmitting the closing force shall be made of metal and shall be designed to withstand a force equal to 5 times the closing force. 6.3.103
Balanced valves The strength of the connection between closure members of a balanced valve shall be at least five multiplied by the maximum inlet pressure multiplied by the total opening area of the closure members. 6.3.104
Bellows When bellows are used as sealing elements proof of limiting fatigue stress shall be provided for at least the number of cycles stated in Table 4. For the calculation not less than the number of cycles as stated in Table 4 shall be taken for the respective nominal widths. SIST EN 16678:2016

The test is carried out in such a manner that deformations of the test sample in all directions are possible. There shall be no additional stresses due to bending, torque or tension. The test is carried out with water at ambient temperature at a pressure according to the values in Table 1 for 5 min. The test may also be carried out with air or nitrogen, if the necessary safety measures are taken. Chambers separated by diaphragms are pressurized on both sides of the diaphragm at equal pressure. 6.4 Gas connections 6.4.1 Making connections Shall be according to EN 13611:2007+A2:2011, 6.4.1 with the following addition: If the valve is equipped with welding ends for welding to the pipe, EN 13611:2007+A2:2011, 6.4.1 is not applicable.
