Globe Valves Cryogenic Bronze Manual Globe Valve
Bolted Bonnet - Extended Stem
Bronze Body with Bronze Internals
DN6 - DN50 (1/4” - 2”)
The Parker Bestobell range of extended globe valves have been designed to
eliminate leakages, maximize lifetime operation and reduce maintenance
and spares cost.
The range is available with either screwed ends, Socket Ends or stubs and
utilizes Parker Bestobell’s unique independent bonnet and flange design,
eliminating leakage through the flange gasket.
The Bronze extended stem globe valve has a bolted bonnet, integral cone seat
and renewable seal, complete with bronze internals. Available with various
ends, the valve is of the cone seat design for drop tight shut off. The bolted
bonnet allows easy maintenance, even in confined spaces.
All valves are degreased for oxygen duty, assembled in clean room conditions
and pressure tested prior to dispatch.
Maximum Working Pressure (MWP)
Subject to end connections
Up to 50 bar (725 psi) at -196°C to +65°C
Features DN15 Bronze Globe Valve

The Parker Bestobell range of non-extended globe valves have been designed
to eliminate leakages, maximize lifetime operation and reduce maintenance
and spares cost.
The range is available with either Butt Weld, socket end or flanged options
and utilizes Parker Bestobell’s unique independent bonnet and flange design,
eliminating leakage through the flange gasket.
The Stainless Steel non-extended stem globe valve has a bolted bonnet,
integral cone seat and renewable PTFE/PCTFE seal, complete with Stainless
Steel internals. Available with various ends, the valve is of the cone seat
design for drop tight shut off. The bolted bonnet allows easy maintenance,
even in confined spaces.
All valves are degreased for oxygen duty, assembled in clean room conditions
and pressure tested prior to dispatch.

Stainless Steel
DN25 & DN40 (1” & 1½”)
The Parker Bestobell cryogenic main fill valve manifold is
specifically designed for cryogenic static storage tanks to
replace the traditional gang of valves linked together with
piping and a large amount of welding and brazing.
It is the joining together of four valves: top fill, bottom fill,
check valve and drain valve. It is available in two sizes
25mm (1”) and 40mm (1 ½”).
The design makes it a simple valve to operate from the
user perspective. The Manifold can be supplied with
various inlet connections to suit customer requirements.
Located within the valve is a spring to close check valve
to prevent back wash of media at the end of the filling
cycle. A drain valve is fitted to release any trapped media
in the fill block. A warm-up leg is also included for the
connection of a thermal relief valve.
The unit is supplied ready to be fitted to the tank, with
pipe specifications supplied by the customer.

Cryogenic Bronze Ball Valve
Reduced Bore
DN15- DN50 (½” - 2”)
Ball Valves This Bronze uni-directional ball valve has been designed
specifically for cryogenic applications. It is available
with NPT or BSP threaded ends.
The flow co-efficient (CV) allows full flow of media from
filling stations and portable delivery systems therefore
no delay in filling time.
Other variations include:
- Stainless Steel Version
- Actuated
- Full Bore
All valves are degreased for oxygen duty, assembled
in clean room conditions and pressure tested prior to
dispatch.
Maximum Working Pressure (MWP)
Subject to end connections
Up to 50 bar (725 psi) at -196°C to +65°C
Features DN50 Bronze Ball Valve with NPT Threaded Ends
• S pring loaded gland seal giving low torque levels
under both ambient and cryogenic conditions
• One piece, anti-blow-out stem
• Relief hole to prevent trapping of liquefied gases
• D esigned to prevent incorrect, and hence
dangerous, re-assembly after stripping for
maintenance
• R emovable centre section designed to industry
standard dimensions, allowing interchangeability in

Nozzle 10 - 20 (3/8” - ¾”)
A range of high quality Bronze relief valves designed to comply with ISO 4126 (Safety
Valves General Requirement), Ad-Merkblatt A2 (Safety Devices against Excess
Pressure) and TUV requirements. They are eminently suited to the protection of static
and road going cryogenic storage tanks against damaging over pressure.
There are three basic sizes, defined by the throat diameter and each is available with a
variety of inlet and outlet connections.
The valve is designed and factory set to lift repeatedly within 2% of the set pressure
and to reseat above 92% of set pressure. Spring pre-compression and blow down ring
settings are sealed after test to inhibit unauthorized tampering.
Flow rates at 10% above set pressure.
All valves are degreased for oxygen duty, assembled in clean room conditions and
pressure tested prior to dispatch.
Each valve is individually set and flow tested and then stamped with the date of
manufacture and its own unique serial number prior to dispatch.

Cryogenic Thermal Relief Valve
Brass
Nozzle 6 (¼”)
Relief Valves A compact cryogenic relief valve designed to prevent
damage to piping and equipment caused by the
expansion of liquefied gases. Nozzle 6 Brass Thermal Relief Valve
Open to Atmosphere
When liquefied gases are trapped between two closed
valves (a situation known as liquid lock) the reheating
and consequent boiling can lead to a dangerous rise in
pressure.
The Parker Bestobell Thermal Relief Valve has been
designed with this application specifically in mind using
materials which are particularly suited to this purpose.
One major benefit of this is that the valve will not stick
in its seat even when left unused for long periods of
time. The valve also reseats correctly after venting off the
expanding fluid, thus preventing the waste of expensive
cryogenic gases. It is available with a variety of outlet
connections to suit the customers’ requirements.
All valves are degreased for oxygen duty, assembled
in clean room conditions and pressure tested prior to
dispatch.
Maximum Working Pressure (MWP)
Subject to end connections
Up to 40 bar (580 psi) at -196°C to + 65°C
Features Technical
• Valve will not stick in its seat even when left unused • D esigned and engineered for use with Group 1
for long periods of time gases.
• D esign allows the valve to reseat correctly after • Designed and manufactured in accordance with
venting off the expanding fluid which prevents ASTM B31.1, BS EN 1626 and BS ISO 21011

• Optional full material traceability backed by
• Accuracy of lifting pressure is +/- 3% BS EN 10204 3.1/3.2 certification.
• Valve is tight up until 90% of set pressure Marked according to the Pressure Equipment
Directive
• Valve reseats before 50% of set pressure
• Orifice diameter is 8mm

Cryogenic Pressure Build Up Valve
Stainless Steel
DN50 (2”)
The Parker Bestobell Pressure Build Up Valve is designed to provide an ‘easy
adjust’ pressure regulation function in one valve.
It is suitable for use on cryogenic static tanks and road trailers. The valve
operation is such that it maintains a system pressure on a container or
storage unit during transfer of gas from the trailer to a storage unit or vice
versa. Pressure must be maintained to allow flow to occur at desired rates
during transfer.
All valves are degreased for oxygen duty, assembled in clean room
conditions and pressure tested prior to dispatch.
