Masoneilan* 31000 Series Rotary Control Valve

 

The 31000 Series valve features a PFA-lined assembly offering corrosion resistance for corrosive fluid applications at a lower cost compared to high alloy options. It also includes an eccentric rotary plug design that offers tight shut-off at a high 100:1 turndown ratio and low dynamic forces for excellent throttling control. 
 
 
 
 
 
 
 
 

 

 

 

Features & Benefits

               
                   
• Complete PFA or solid PTFE encapsulation of all metal components shields against chemical corrosion for long service life in harsh chemical environments
 
 
• Eccentric plug design drastically reduces seal friction, reducing actuator sizes for extended seat life, fewer maintenance requirements and increased process yields
 
 
 
• Eccentric plug action offers accurate control and tight class VI shut-off
   
• Standard low-emission packing system offers compliance with environmental and safety requirements
