Disassembly

► Note that the union bush has left-handed thread.
WARNING!
Risk of injury due to uncontrolled evasion of the medium!
If the pressure was not relieved completely, the medium can evade uncontrolled. Depending on the type of medium, risk of injury may
exist.
► Completely relieve pressure in the pipes prior to dismounting.
► Completely empty and rinse pipe prior to dismounting in connection with harmful, flammable, or explosive media. Pay attention
to potential residues.
► Provide for safe collection of the medium by implementing appropriate actions (e.g. connection of a collection container). After
dismounting, the ball valve should be stored or disassembled.
► Partially open the dismounted ball valve (45° position) and let drain in vertical position.

Maintenance

Ball valves require no maintenance under normal operating conditions. However, following measures must be noted:
► Periodic inspection to make sure that no medium is leaking is sufficient.
► Make a function test for ball valves which are kept permanently
► Recommendation when using aggressive media: periodically (depending on the aggressiveness of the medium as well as the
utilization of the goods) remove the ball valve from the line by loosening the union nuts and check the inside for damage.
For frequent control operations – valve automation, or due to chemical attack on the sealing material – it may become necessary to
replace parts inside the valve. For this purpose, the valve must be removed from the piping system. The sealing elements, as well
as the ball, stem and union bush can be replaced, see spare parts list of GF Piping Systems.
CAUTION!
Material damage and/or risk of injury!
Only original GF spare parts designed specifically for this valve may be used for replacement purposes.
► Note all the details given on the type plate when ordering spare parts.
► Lubricate seals with GF-specified lubricant.
► Never use petroleum-based greases or Vaseline (Petrolatum).
► Observe manufacturer's instructions for specially cleaned ball valves ex works.
► All the seals react to environmental influences. They must therefore be kept in their original packaging, and stored cool, dry and
dark.
► The seals should be checked for damages from aging, such as fissures and hardening, before mounting.
► Do not use defective spare parts.
