OPD device designed to automatically reduce the filling rate to a minimal flow when the fill level reaches a predetermined amount 3.18 occasional liquid withdrawal valve normally blanked valve, used for occasional liquid withdrawal which is designed to be opened by the engagement of a special connector valve 3.19 internal valve valve which has its seal within the profile of the pressure vessel 3.20 self closing valve normally closed valve that provides a leak tight seal, opens by the engagement of a special connector or by fluid passing through it and closes automatically upon removal of the connector or by stopping the fluid flow 3.21 vapour equalizing valve valve which permits vapour to flow in either direction in order to equalize vapour pressure between pressure vessels during liquid transfer, and which incorporates an excess flow valve and a self-closing valve opened by a special connector valve 3.22 multipurpose valve valve which incorporates two or more service functions and which meets the combined requirements of the individual functions 3.23 breakaway coupling coupling which separates at a predetermined section when required and each separated section contains a self-closing shut-off valve, which seals automatically Note 1 to entry: Also referred to as a safe break. 3.24 dry disconnect coupling quick coupling which connects and disconnects with minimum LPG release and each separated section contains a self-closing shut-off valve, which seals automatically 3.25 Standard Temperature and Pressure STP 15,6 °C (288,7 K), 1,013 bar absolute (0,101 3 MPa absolute) 4 Operating conditions 4.1 Valves and fittings designed in accordance with this European Standard shall be suitable for a minimum operating temperature of −20 °C. NOTE In service, temperatures below this can be encountered during short periods, for example, during filling. 4.2 cor some parts of burope and certain applications, temperatures lower than −20 °C can be encountered; for these conditions the requirements of Annex B shall be applied.

Figure 1 — Hand-wheel marking 7.3.3.2 Valve body Where the valve body is made of more than one component, precautions shall be taken to ensure that there can be no unintentional disassembly. Disassembly shall require specialized equipment. 7.3.3.3 Sealing mechanism The mechanism shall ensure internal leak tightness. 7.3.3.4 Operating torque After the endurance test in accordance with 8.7 which is representative of the service valve life, the operating torque shall not exceed 3 Nm. 7.4 Filler valve 7.4.1 The filler valve shall be either: a) manually operated; or b) a remotely operated shut-off valve in combination with a non-return valve; or c) a double non-return valve, at least one of which meets the requirements of 8.5, the other non-return valve may meet the requirements of either 8.5 or 8.6; or d) a system that provides an equivalent level of safety. 7.4.2 Where supplied as an assembled unit, the filler valve shall meet the following criteria: a) the non-return valve components shall meet the requirements of 7.2; and b) where liquid can be trapped, means shall be provided to relieve excess pressure; and c) where the body is made of two or more components, it shall not be possible to disassemble the components with a torque of less than 80 Nm. 7.4.3 The device shall have a minimum filling rate greater or equal to 8 m3/h (water) under a differential pressure of 4 bar. 7.4.4 The fill connection shall be provided with a leak tight cap or blind flange. When the fill connection is provided with a soft-seated non-return valve in combination with a shut-off valve, a leak tight cap shall not be required. Consideration shall be given to providing dust protection. NOTE Plugs and caps can be provided with a locking mechanism to prevent unauthorized interference. 7.4.5 Typical filler valve inlet connections are listed in Annex A. When a dry disconnect coupling is used as a filler valve, the essential dimensions for a DN 50 and DN 80 connections are shown in Annex D. SIST EN 13175:2015
