B38
● Compact instrument units with high performance
● Stable regulation with temperature compensation
● Excellent flow and regulation characteristics
● Panel Mounting facility
● Designed for use in corrosive environments
● Metallic parts meet NACE Standard MR-01-75*
● Applications include marine environments, oil and
gas production, chemical and food processing,
medical analysis
● Relieving or non relieving models. Relieving models
allow reduction of outlet pressure even when the
system is dead-ended
* National Association of Corrosion Engineers (NACE) MR-01-75 defines requirements for
sulphide stress cracking resistant materials used in well-head and other corrosive environments.
