Masoneilan™ 31000 Series
Rotary Control Valve
The 31000 Series control valve is a PFA lined, eccentric plug control valve for corrosive applications which incorporates the following features:
Reliability
Dovetail grooves mechanically anchor the PFA lining, while the robust rolling diaphragm actuator provides positive fail-safe action with enclosed linkage and adjustable locking stops.
Reduced Fugitive Emissions
Rotary design minimizes packing wear compared to linear valves; standard PTFE/Graphite packing with chevron rings and double O-ring follower enhances sealing reliability.
Excellent Performance
The eccentric rotary plug design delivers precise throttling control, low dynamic forces, tight shutoff, and high flow capacity with a straight-through flow pattern.
Ease of Maintenance
Compact, lightweight design enables easy installation and removal without compromising piping forces or system integrity.
