SRD valve positioners
The Badger Meter research control SRD series of smart valve positioners deliver 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 analog valve positioners.
The SRD 960 (explosion-proof) and SRD 991 (intrinsically safe) digital valve positioners are suitable for the chemical, petrochemical, water and wastewater, oil and gas, food and beverage, and pharmaceutical industries. An optional base model, the SRI 990, has analog valve control with fast control behavior. The positionerís control boards can be swapped out to upgrade from a SRI to a SRD.
The SRD/SRI positioners are compatible with research control valves and most other pneumatically actuated valves. The positioners can be used for both new valve installations and retrofitting existing valves. They reduce the adverse effects of online valve friction, enabling higher thrust and shorter positioning time. Users can add optional limit switches.
