Bestobell Cryogenic Pressure Regulator
The Parker Bestobell cryogenic pressure regulator (also known as Cryoreg) is used to regulate pressure of storage vessels, including static and transportable tanks. It features combined pressure build-up, regulator and economiser regulation functions within one valve.
This includes:
• Pressure build up regulator
• Economiser valve
• Thermal relief on two of the ports
Cryoreg is designed to fit downstream of the pressure build-up coil and therefore controls the gaseous flow during the pressure build up phase of its operation. 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.
Maximum Working Pressure (MWP)
Subject to end connections
Up to 25 bar (360 psi) at -196°C to + 65°C
Features
• Combined pressure build-up regulator and economiser functions for simpler pipework and fewer joints • High flow characteristics – for closer control of tank pressure
• Operates on liquid or gas – to suit every installation
• Single adjustment for both functions – for simpler tank setting
• High accuracy/low deadband allows higher tank pressure – reduced boil-off in pipelines
• Dual thermal relief valve action – for added system protection
• Strainer fitted as standard on inlet and outlet
• Ball check fitted to economiser outlet as standard
Technical
• Designed and engineered for use with Group 1 gases. •
DN15 – DN25 bull nose end connections available. Please contact us with your requirements.
• Designed and manufactured in accordance with ASTM B31.1, BS EN 1626 and BS ISO 21011
• Optional full material traceability backed by BS EN 10204 3.1/3.2 certification.
The Cryoreg is available with a choice of springs to give optimum control in all applications. Set pressure tolerance will normally be held on gas ± 3% and liquid side ± 5%.

Bestobell Cryogenic Pressure Build Up Valve
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 maintains a system pressure on a container or storage unit during transfer of gas from the trailer to a storage unit or vice versa, therefore optimising safety. As the pressure falls, the valve opens and allows liquid to pass into the vaporiser. The gas generated is returned to the vapour space at the top of the vessel.
It has high flow characteristics, enabling it to fill or empty the tank quickly. 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
• High flow characteristics for closer control of tank pressure
• Operates on liquid or gas to suit every installation
• Single adjustment for ease of tank setting
• Inlet strainer fitted as standard fitted as standard to all valves
• Removable cartridge internal system for ease of maintenance
• Available with a choice of springs to give optimum control in all applications
Technical
• Designed for use with: C, Ar, O2, CO2
• DN50 Flow data: Cv = 12.5 US GPM; Kv =10.8 M3/hr
• Optional full material traceability backed by BS EN 10204 3.1/3.2 certification
