    RESPONSIBILITY FOR VALVE APPLICATION The User is responsible for ordering the correct valves. The user is responsible for ensuring APV Valves are selected and installed in conformance with the current pressure rating and design temperature requirements.

  • Page 6: Safety Information

    This manual provides instructions for storing, general servicing, installation and removal of globe valves. APV and it’s resellers refuse any liability for damage to people, property or plant as well as loss of production and loss of income under any circumstances but especially if caused by: Incorrect installation or utilisation of the valve or if the valve installed is not fit for intended purpose.
  • Page 7 If a gasket seal is disturbed while removing or adjusting gasketed parts, APV recommends installing a new gasket while reassembling. A proper seal is required to ensure optimum operation.
  • Page 8 V A L V E I D E N T I F I C A T I O N Each APV valve is identified with a nameplate, which is placed over the handwheel and secured with the hand wheel nut on gate and globe valves, and riveted to the cover on check valves. Below is an example.

  • Page 10: Preparation For Installation

    GLOBE VALVES OS & Y - FORGED - ISO 15761/API 602/B16.34 1.2 PREPARATION FOR INSTALLATION • Remove protective end caps or plugs and inspect valve ends for damage to threads, socket weld bores or flange faces. • Thoroughly clean adjacent piping system to remove any foreign material that could cause damage to seating surfaces during valve operation.
  • Page 11 PWHT depending on material specifications. APV forged globe valves do not run the risk of seat loosening during welding due to the fact that they are supplied with integral Stellite body seats.
  • Page 12 GLOBE VALVES OS & Y - FORGED - ISO 15761/API 602/B16.34 Special trim options and body materials such as valves with PTFE packing/soft seat/ special seals/ and gaskets that have maximum temperature limits less than the valve, may require special welding and heat treatment considerations which are not included herein.

  • Page 15 GLOBE VALVES OS & Y - FORGED - ISO 15761/API 602/B16.34 Over tightening will cause the packing to fail prematurely as well as increasing the force required to operate the valve. The packing gland flange should not bend even slightly, if it does you have over-tightened the valve and have to replace the flange. If the leak cannot be stopped by tightening the gland nuts, it is necessary to add additional packing rings or completely repack the valve.

  • Page 16: Packing Replacement

    GLOBE VALVES OS & Y - FORGED - ISO 15761/API 602/B16.34 Under no circumstances should the back seat be used to allow gland packing replacement or repair while the valve and system are pressurised. One of the most common misunderstandings is to believe that is the Globe valve is back seated (fully open position - and backseat sealing made), this will help to prevent wear of the packing rings.
  • Page 17 3.4 PREVENTATIVE MAINTENANCE AND PERIODIC INSPECTIONS APV recommends that periodic inspections be carried out on all valves. The frequency of these inspections depends on the severity of the service and the frequency of the valve operation. As a minimum, all valves should be inspected quarterly to ensure proper operation and discourage the damage compounding effects of leakage.
  • Page 18 Regular maintenance of the valve is required to assure smooth operation. Stem threads should be inspected and lubricated frequently to ensure ease of operation. APV valves are supplied with the stem threads engaging the yoke nut pre-greased. These components should be kept constantly lubricated by applying the grease directly on the stem when the valve is in the open position or through the grease injector in the yoke nut when provided.

There are different designs of pressure seal bonnet: - locknut type (breech lock), bonnet take-up type (bolted yoke arm) and the bolted style, hence, refer to as-built drawings.
  • Page 25 These valves are available with either threaded-in seat rings or an integral seat, both of which may be repaired (threaded in seats shall be replaced) while the valve is in line.

However, due to its loose design, it is necessary to prevent the disc from rotating on the stem. After lapping it is recommended that the surface of the seat and disc be checked for proper contact using marking blue.
