PLEASE NOTE:
If the valves produced by Parker Hannifin Bestobell Valves/LNG are refurbished by a third party
organisation that is not approved by Parker Hannifin Bestobell Valves/LNG, then the safety and
performance will not be guaranteed and the warranty may be invalid.
If unsure about the installation and operation procedures for this valve, please contact Parker
Hannifin Bestobell Valves/LNG.
Parker Hannifin Bestobell Valves has produced this manual in order to provide engineering personnel
with sufficient general information to enable the operation, installation and effective maintenance of
the valve manufactured by Parker Hannifin Bestobell Valves.
In the interest of product development, the designs and specifications for our products are constantly
under review and we therefore reserve the right to make changes and improvements without notice.

Introduction
Outline
This manual is broken down into separate sections:
•Introduction
This section provides information about important safety requirements as well as highlighting
the precautions taken at Parker Hannifin Bestobell Valves to ensure the cleanliness of our
products. Details regarding servicing are also introduced.
•Installation
This details the method of installing the valve on site, and includes information on storage,
unpacking and inspection. Preparation of the valve and site is also discussed to allow ease of
installation and operation.
•Hardware Description
Introduces the product as well as providing a more detailed description including operating
conditions and suitable media. Any further requirements for the effective operation of the valve
are also discussed.
•Maintenance
Provides information relating to the on-site maintenance of the supplied valve, as well as
discussing common problems and solutions.
Safety
Read and understand these instructions before installing the valve. Improper installation,
operation or maintenance by the owner or operator of this valve can result in personal injury.
Only use genuine Parker Hannifin Bestobell Valves spares to ensure safe and optimum performance.
Prior to the installation of the valve into the system and any maintenance work, ensure the system is
de-pressurised and isolated for the duration of the installation and during any subsequent
maintenance.
The valve must be installed within a system that has adequate draining and venting provisions.
In cryogenic applications the area of pipe-work to receive the valve must be allowed to reach ambient
temperature.
It is essential that the installers and operators are conversant with all of the safety issues relating to
the medium within the system, and are fully trained to an adequate standard.

Wear safety glasses and gloves during any installation or operation of the valve.
Valves must only be used in a circuit protected by suitable equipment.
The valve should be inspected for wear as part of a regular system maintenance programme.
Cryogenic burns can occur if the valve is handled during or after the valve has operated.
Minor leaks from the outlet side of the valve, if allowed to build up in a confined area, can be
hazardous. This can be avoided by dissipating into the atmosphere or a well ventilated area.
If valve is to be installed in hazardous climatic conditions or seismic areas, please inform Parker
Hannifin Bestobell Valves.
Identify the intended flow direction and match the valve orientation with its flow direction arrow.
Ensure that all end connections to the valve are in line and that the pipe work is supported to reduce
unwanted stresses, loading and vibration on the valve and system pipe work.
Ensure that all joining materials / components used during the installation of the valve are compatible,
and will not cause any deterioration to the valve structure.
When using on CO2, the internal atmosphere must be dry and moisture free as any bronze
components could be affected by carbonic acid.
DO NOT check leaks with hands.
Cleanliness
Immediately after assembly in a controlled clean room, the valve is sealed in an airtight plastic bag to
maintain cleanliness. As such, it is essential to maintain this cleanliness throughout all stages of
installation. Particular care should be taken not to contaminate the internals of the valve with grease,
moisture, grinding dust, weld/brazing spatter etc.
Clean practices will save time later with reduced ‘flushing’ and maintenance.

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.

STORAGE:
The equipment packing cases are NOT waterproof and should be stored in a weatherproof location
before use.
UNPACKING:
It is recommended that before any item is unpacked, it should be moved as close as possible to its
installed position. This will minimise the possibility of damage during handling.
Before unpacking, items should be checked to ensure their part number is in line with requirements
and/or the purchase order.
The valve should be inspected for damage upon receipt - any problems are to be immediately
reported to Parker Hannifin Bestobell. This should be done within 48 hours of receipt of goods
otherwise a warranty claim may be rejected.
It is further recommended that each item should only be unpacked immediately before it is required.
Before installation the engineer should check for:
•Damaged Packaging
•Bent or Distorted Items
•Scratches, Dents or Damage
Particular attention should be paid to the sealing faces on the end connection flanges.
TOOLS REQUIRED:
No special tooling is required for the installation of this valve.

Preparation
WARNING!
BEFORE ANY INSTALLATION AND MAINTENANCE WORK CAN
COMMENCE ENSURE THE VALVE AND SURROUNDING SYSTEM IS
DRAINED OF PRESSURE AND ISOLATED.
Remove the headwork before installation and cover the top of the body to protect the internals of the
valve from particulate contamination.
Also ensure that enough room is left above / around the valve for the headwork once this is replaced
after installation.
Identify the intended flow direction and match the valve orientation with its flow direction arrow.
Ensure that all end connections to the valve are in line and that the pipe work is supported to reduce
unwanted stresses, loading and vibration on the valve and system pipe work.
Ensure that all joining materials / components used during the installation of the valve are compatible,
and will not cause any deterioration to the valve structure.
