SRD/SRI Valve Positioners
Research Control® SRD smart valve positioners deliver actionable diagnostic information about valve performance and assist compliance with fugitive emissions regulations. SRI analog valve positioners are also available. The SRD 960 (explosion-proof) and SRD 991 (intrinsically safe) digital valve positioners are economical solutions for diverse applications. An optional base model, the SRI 990, provides analog valve control. Users can easily upgrade from SRI to SRD.
- Compatible with most pneumatically-actuated valves
- Easily mounts to all linear and rotary actuators
- Reduces effects of on-line valve friction
