Masoneilan 31000 Series Rotary Control Valve

Product catalog summary
Overview: The GE Oil & Gas Masoneilan 31000 Series Rotary Control Valves are designed for corrosive applications, featuring a PFA liner and eccentric rotary plug for enhanced performance and reliability.
Key Features:
  • Performance: Eccentric rotary plug design ensures accurate throttling control, low dynamic forces, and tight shut-off with high flow capacities.
  • Corrosion Resistance: PFA lining with a guaranteed minimum wall thickness offers resistance to most corrosive fluids.
  • Reduced Emissions: The rotary design minimizes packing wear, complemented by PTFE/Graphite packing and a double O-ring follower for reliability.
  • Maintenance: Compact and lightweight design facilitates easy installation and removal.
  • Reliability: Dovetail grooves anchor the PFA lining to the metal body, ensuring performance under vacuum and high temperatures. The actuator is equipped with a rolling diaphragm for fail-safe action.
Specifications:
  • Body and Bonnet: Made from nodular ductile iron with PFA lining, available with optional steam/hot water jacket.
  • Trim: Eccentrically rotating plug with PFA coated stainless steel, conical seat ring sealed with O-ring.
  • Actuator: Spring-opposed rolling-diaphragm type with optional manual actuator.
Connections and Ratings:
  • Available in various sizes with PN and ANSI connections.
  • Pressure/Temperature Rating: Suitable for vacuum operation within the specified temperature range.
  • Seat Leakage: Class VI according to IEC 534-4 and ANSI/FCI 70.2.
Materials of Construction:
  • Body and Bonnet: Ductile Iron ASTM A395/PFA Lined.
  • Plug: PFA encapsulated Stainless Steel.
  • Seat Ring: Virgin Solid PTFE.
  • O-Rings: FEP coated Viton®.
