      Model 371MT7 Position Indicator for Series II & Series III-L Valves 
      
      Reliable valve position feedback for Series II & Series III-L Valves 
      
        
       
      
        
      Description 
      
        
      Barksdale's position indicators are sensitive feedback devices that can be attached to Series II & Series III-L valves to provide valve status feedback. Using Barksdale's know-how in electric switch technologies, the position indicator senses any of the three valve positions and signals this information through an electrical contact. With a housing constructed of all stainless steel material, this product is designed for use in heavy industrial environments and in the most demanding applications. The explosion proof rating is Division I, Class I. 
      
        
      In applications where feedback from the valve is desirable, Barksdale's position indicator replaces such devices as proximity sensors, pressure switches and limit switches. Position indicators come already installed and calibrated on our Series II & Series III-L valves, saving installation costs for the customer.
