Series LPV-A/F, LPV-D/F 2 Seite 6 Notes on safety This operating manual contains fundamental information which is to be observed during installation, operation and maintenance. It must be read before installation and commissioning! For low-pressure safety valves which are used in potentially explosive areas, see Section 3. Installation, operation and maintenance are to be performed by qualified staff. The area of responsibility, authority and supervision of the staff must be regulated by the customer.
Series LPV-A/F, LPV-D/F 3 Seite 7 Safety notes for applications in potentially explosive areas based on the Directive 94/9/ EC (Atex 95) The valves are intended for use in a potentially explosive area and are therefore subject to the conformity assessment procedure of the directive 94/9/EC (ATEX).
Series LPV-A/F, LPV-D/F 4 Safety note for valves, certified to Clean Air Act (TA-Luft) On request, this valve can be supplied compliant with the German Clean Air Code. Certificate / Manufacturer Declaration Validity is dependent on the operating instructions being read and observed. 5 Seite 8 In particular, servicing must be conducted at regular intervals, and the bolted connections relevant for tightness must be inspected and retightened if necessary.
Series LPV-A/F, LPV-D/F 6 Seite 9 Installation The installation conditions to the AD 2000 Code A2 (on pressure vessels) and TRD721 are to be observed. They are major preconditions for the safe operation of the valve. Examine valve for in-transit damage, damaged low-pressure safety valves must not be installed. Before installation the valve and the connecting pipe must be carefully cleaned to remove any dirt, especially hard foreign matter.
Series LPV-A/F, LPV-D/F 6.2.3 Discharge conditions and reaction forces At low temperatures: Outlet lines must be protected against freezing. This applies in particular if gas cooling as a result of expansion is to be expected or lines are laid outdoors. With crystallising media: In the case of media which tend to crystallise, solidify or stick, appropriate action must be taken to ensure that the solidification process cannot take place in the inlet or outlet lines or in the body (e.g.
Series LPV-A/F, LPV-D/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. The max. operating pressure of the plant must always be below the safety valve reseating pressure.
Series LPV-A/F, LPV-D/F 8 Seite 12 Malfunctions • Safety valve is leaking Is there foreign matter between the seat and plug? Is there any wear or damage to the seat or plug? If so, it is necessary to rework the sealing surfaces of the seat and plug or replace these components. • The valve stroke is not reached. Check of dimensions as per dimensional drawing required. See Section 10. • Medium is escaping at the bonnet Are the screws 901/1 and 902/2 tightened with hex.
Series LPV-A/F, LPV-D/F 9.4 Changing the test gauge pressure Unscrew bonnet 112. Remove subassembly shut-off element. Remove retainer ring 544 and round cord 522. Push number of weights 239, depending on the test pressure, onto the plug 204. See Section 6.5. Secure with round cord 522 and retainer ring 544. Install subassembly shut-off element in the body 100. Screw on bonnet 112 and tighten. Check test pressure. Have valve lead-sealed. The data specified in the data sheet are to be observed. 9.
Series LPV-A/F, LPV-D/F Seite 14 Only LPV-D/F DN 50: Attach the centering ring 549 onto the body centering. Insert guide of the bonnet into the plug and place on the flange. First tighten the attachment nuts 920/2 hand-tight and then with a torque wrench evenly and in diametrically opposite sequence. It is imperative to observe the prescribed torques for the connection body / bonnet! See Section 1.4. 9.6 Tests Following the assembly of the valve, the stroke and the test pressure must be checked.
