Series GU/F 2.1 Intended use Richter overflow valves of the GU series are pressuremaintaining components in accordance with the Pressure Equipment Directive (DGRL) for the passage of fluids at a given test pressure. GU are only intended for vertical installation. The valves are suitable for non-boiling liquids of group 1 in acc. with the Pressure Equipment Directive (DGRL). They have a corrosion-resistant plastic lining.
Series GU/F A difference is made between two cases for the use of -8 chargeable liquids (conductivity <10 S/m): 1. Chargeable liquid and non-conductive lining Charges can occur on the lining surface. As a result, this can produce discharges inside the valve. However, these discharges cannot cause ignitions if the valve is completely filled with medium. If the valve is not completely filled with medium, e.g. during evacuation and filling, the formation of an explosive atmosphere must be prevented, e.g.
Series GU/F 5 Page 8 Transport, storage and disposal It is imperative, for all transport work, to observe generally accepted engineering practice and the accident prevention regulations. The overflow valve is supplied with flange caps. Do not remove them until just before installation. They protect the plastic surfaces against dirt and mechanical damage. Handle the goods being transported with care. During transport the valve must be protected against impacts and collisions.
Series GU/F 5.4 Disposal Parts of the valve may be contaminated with medium which is detrimental to health and the environment and therefore cleaning is not sufficient. Risk of personal injury or damage to the environment due to the medium! 6 Page 9 Wear protective clothing when work is performed on the valve. Prior to the disposal of the valve: Collect any medium, etc. which has escaped and dispose of it in accordance with the local regulations. Neutralise any medium residues in the valve.
Series GU/F Page 10 A draining facility must be provided at the lowest point in the pipe. This opening for the drainage of condensate must be lower than the flow chamber of the body. 6.4 Contamination of or damage to the sealing surfaces is best avoided if the protective caps remain on the flanges until just before installation. We recommend the installation of gaskets so that the sealing surfaces are not damaged by the mating flanges.
Series GU/F 6.6 Page 11 Grounding 6.9 The valve must be grounded. The simplest solution is to use tooth lock washers which are placed under one pipe bolt of each flange. At the customer's request a setscrew M6 with a hex. nut and washer will be provided at each flange as an additional grounding connection. Otherwise grounding must be ensured by different measures e.g. a cable link. 6.7 Installation Signal transmitter (Option) On request, an signal transmitter is available for remote monitoring.
Series GU/F 7 Operation 7.1 Initial commissioning Normally, the valves have been tested for leaks with air or water. Unless otherwise agreed, there could be residual amounts of water in the flow section of the valve; this could result in a possible reaction with the medium. Following the initial loading of the valve with operating pressure and temperature, the torques of all connecting bolts must be checked. See Section 1.3. 7.2 Page 12 7.
Series GU/F 8 Page 13 Malfunctions Overflow valve is leaking Is there foreign matter between the seat and plug? Is there any wear or damage to the seat or plug? Have the nuts at the inlet nozzle been unevenly tightened? Actuation of the lifting lever can help to regain the required sealing effect. If this does not succeed in stopping the leak, the sealing surface of the plug must either be reworked or the plug or seat must be replaced.
Series GU/F 9.3 Modification of the overflow valve If modifications to the valve are required, the manufacturer must always be consulted. Examples: Modification with changed test pressure, replacement of the spring or adaption to the mass flow by reducing the travel. After approval by the manufacturer, these modifications can be performed either by the manufacturer or by the customer under the guidance of a technical supervisory agency or any other approval authority. 9.
Series GU/F Undo the hex. socket screws 914/1. Centre the spring bonnet 513 with internals on the body 100. Ensure that there is metallic contact between the body and the spring bonnet. Then tighten the screws 901/1, 936/1, 936/2 and 920/2. Tighten the hex. socket screws 914/1 for the bellows seal evenly in line with the tightening torques in Section 1.3. Undo stem nut 534. Remove distance sleeve. Screw stem nut 534 onto the stem 802 up to the marking. Then counter with the self-locking hex. nut 929/1.

Safety Information / Declaration of No Objection Concerning the Contamination of Richter-Pumps, -Valves and Components 1 SCOPE AND PURPOSE Each entrepreneur (operator) carries the responsibility for the health and safety of his employees. This extends also to the personnel, who implements repairs with the operator or with the contractor. Enclosed declaration is for the information of the contractor concerning the possible contamination of the pumps, valves and component sent in for repair.
Declaration about the Contamination of Richter Pumps, -Valves and Components The repair and/or maintenance of pumps, valves and components can only be implemented if a completely filled out declaration is available. If this is not the case, delay of the work will occur. If this declaration is not attached to the devices, which have to be repaired, the transmission can be rejected. Every aggregate has to have it’s own declaration.
