Foxboro SRI983-CIRMFDZN-L Positioner

Foxboro SRI983-CIRMFDZN-L Positioner

SRI983-CIRMFDZN-L Electro-Pneumatic Positioner — explosion proof or EEx d version
The SRI983 Positioner is designed to control pneumatic valve actuators from control systems and electrical controllers with electric control signals.
It is used to reduce the adverse effects of valve friction, for higher thrust and shorter positioning time.It offers an easy adjustment by two mechanical screws.For complete specification, refer to Product Specification Sheet PSS EVE0103 A-(en).
