Installation and maintenance instruction for 2PC ball valve ABRA-BV41 DN200-300 PN16 with direct mounting pad ISO top flange and gear:

• General.
  • The valve should be installed only by person who has enough experience, carefully read the following instruction and got appropriate safety training for that kind of work.
  • Before mounting you should check the valve for transportation or storage damage.  If you find that you should stop mounting until you get Seller's approval. 
• Special note for installation of valves with electrical actuators.
  1. Before installation the valve and the actuator should be set-up properly for for combined operation as it demanded according to actuator producer's manual:
     1. Check the assembly or assemble valve and actuator;
     2. While mounted in any orientation but for strictly vertical the actuator should have own supporting structure undependable from the valve;
     3. Installation of actuator below the valve is strongly not recommended;
     4. Set up end position limit switches of the actuator for "On" and "Off" and check safety torque limit switches of the actuator;
     5. Make few cycles of opening and closing of the valve with manual gear of actuator;
     6. If manual operation ; was well, then you should make proper connection to electricity and make few cycles of opening and closing of the valve automatically. Only after that if operation is normal you can mount the valve to the pipeline.
• Mounting.
  • You should obligatory follow "General Installation and Commissioning demands"
  • Delete plastic plugs before mounting.
  • Before mounting consider hazardous liquids or gases in the pipeline i.e. - what is in the pipeline or what may have been in the pipeline at some previous time. Consider: flammable materials, substances hazardous to health, extremes of temperature.
  • Before mounting consider hazardous environment around the product i.e. - Consider: explosion risk areas, lack of oxygen (e.g. tanks, pits), dangerous gases, extremes of temperature, hot surfaces, fire hazard (e.g. during welding), excessive noise, moving machinery. Consider the effect on the complete system of the work proposed. Will any proposed action (e.g. closing isolation valves, electrical isolation) put any other part of the system or any personnel at risk? Dangers might include isolation of vents or protective devices or the rendering ineffective of controls or alarms. Ensure isolation valves are turned on and off in a gradual way to avoid system shocks. Ensure that any pressure is isolated and safely vented to atmospheric pressure. Consider double isolation (double block and bleed) and the locking or labelling of closed valves. Do not assume that the system has depressurized even when the pressure gauge indicates zero. Allow time for temperature to normalize after isolation to avoid the danger of burns and consider whether protective clothing (including safety glasses) is required.
  • Before starting work ensure that you have suitable tools and/or consumables available. Use only genuine ABRA replacement parts. Consider whether you and/or others in the vicinity require any protective clothing to protect against the hazards of, for example, chemicals, high/low temperature, radiation, noise, falling objects, and dangers to eyes and face.
  • Ball valve can be installed to the pipe in any orientation.
  • Ball valves could be installed in any space direction on the pipeline.
  • Before installation, the pipe must be cleaned. If necessary, valves must be cleaned from dirt and dust too.
  • During installation in the pipeline, flanges of the pipeline must be exactly parallel to flange connections of the valve.
  • Flange connection screws are tightened with a torque spanner (Torques according to EN921 - 934 or ISO4732, 4032, 4017 etc.) Tighten the screws in a crosswise sequence. Flanges rods or bolts should be tightened in evenly cross-cross way in three or four passes as shown on the picture:
  • 
  • If tightening load in flange connection is weakening due to relaxation in gasket or fixture, or in case when technological process is very cyclic in pressure or temperature the additional tightening of flange connection could be necessary. In most heavy cases (very-very rare) using strong cap washers can help.
• Maintenance.
  • The ball valve should be checked visually not less than once per year or more times if that is necessary according to ambient conditions or/and frequency of operations.
  • To avoid trim jam the valve should be run the cycle "fully open"/"fully closed" not less than once every 6 month.
  • No special treatment is needed for all lifetime of the valve.
• Transportation and Storage.
  • Storage and transportation should be without shocks at temperature range: -60…+65°С.
  • No parts or objects are allowed to be placed into ball valve ABRA-BV41.
  • The valve should be kept in clean and weatherproof placements.
  • During transportation ball valve ABRA-BV41 should be properly protected from damage.
• Attention!
  • Don't touch valve in operation due to the possible dangerous temperature.
  • Before service or/and mounting works you must ensure that the valve is not under the pressure and don't have dangerous temperature.
  • Never delete marking from the valve.
• Guarantee.
  • Guarantee is 12 month from installation but not more than 18 month from shipment if all demands of this manual are fulfilled.
  • Customers and stockists are reminded that under EC Health, Safety and Environment Law, when returning products to ABRA they must provide information on any hazards and the precautions to be taken due to contamination residues or mechanical damage which may present a health, safety or environmental risk. This information must be provided in writing including Health and Safety data sheets relating to any substances identified as hazardous or potentially hazardous.
