Pressure Build-Up Regulator and Economiser
DN15 (½”)
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.
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%.
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
