Badger Meter has announced the introduction of the Research Control SRD series of smart valve positioners that deliver robust, actionable diagnostic information about valve performance and help process industry facilities comply with recent fugitive emissions regulations. Badger Meter also released the Research Control SRI series of analogue valve positioners.
The SRD 960 (explosion-proof) and SRD 991 (intrinsically safe) digital valve positioners provide economical and user-friendly solutions for industries such as chemical, petrochemical, water and wastewater, oil and gas, food and beverage, and pharmaceutical. An optional base model, the SRI 990, provides analogue valve control with fast control behaviour. The positioner’s control boards can be swapped out to upgrade from an SRI to an SRD. The SRD/SRI positioners are compatible with Research Control valves and most other pneumatically actuated valves. The positioners are ideal for both new valve installations and retrofitting existing valves.
The SRD provides real-time performance statistics and facilitates both proactive and reactive process management. The SRD is available with different communication protocols, including analogue setpoint (4 to 20 mA) without communication and with superimposed HART signal, and digital with FOUNDATION fieldbus H1 or Profibus PA communications to provide connectivity to supervisory control and data acquisition systems. The compact SRD/SRI series easily mounts to all linear and rotary actuators. Models are offered in IP66 and NEMA 4X enclosures, as well as optional stainless steel housing, with ATEX and Factory Mutual (FM) approval for use in EEx flameproof and intrinsically safe environments.
