Service Intervals
Parker Hannifin Bestobell Valves recommends that a major service is carried out on its valves in line
with the procedures contained in this manual every 2 years.
In addition to this, a regular inspection should take place to ensure correct operational condition.
Regular inspections are suggested on a monthly basis and maintenance work should be carried out
in line with this service manual.
It is recommended that the Service Record Sheet enclosed be fully completed at every service
interval.
Installation
Personnel carrying out Assembly / Joining / Welding / Inspection must be adequately trained and hold
the necessary approvals.
Ensure that environmental conditions (atmospheric pollution) are compatible with the valve materials.
(NOTE: Ensure there is enough space around the valves installed position to allow the removal and
refit of the headwork / valve)
Installation Overview
The quality of performance in service is a function of the care taken to ensure good installation. A
careful study of these instructions is therefore recommended, as properly installed equipment will
normally operate for long periods without problems.
The most critical point in the lifetime of a valve is the time of installation, therefore, proper care at this
stage and during any maintenance will increase the probability of trouble free valve service.
It is important to maintain cleanliness throughout all stages of the installation, with particular care
being taken not to contaminate the internals of the valve with grease, moisture, grinding dust, weld /
brazing spatter or other foreign matter.
Clean practices will save time later with reduced 'flushing' and maintenance.
