Durco G4 Sleeved Plug Valves

Features

Durco G4 lined plug valves are industry-proven solutions for reliable flow control in highly corrosive and hazardous applications. Designed and manufactured by Flowserve, the G4 series is widely recognised for its durability, tight sealing and long service life in aggressive chemical environments. The valve features a fully lined body and plug, typically with PTFE or PFA fluoropolymer materials, providing exceptional resistance to corrosion and chemical attack. Its quarter-turn operation allows for fast and simple actuation, while the sleeved plug design ensures bubble-tight shut-off and minimal maintenance requirements.

 

Features:

  • Dependable, tight shutoff and in-line seal adjustment from tapered plug design
  • Lower maintenance costs due to design that utilises two adjuster fasteners that permit in-line seal adjustments under pressure within seconds
  • Low fugitive emissions through fluoropolymer reverse-lip diaphragm that provides a pressure-activated, self-energising dynamic and static stem seal
  • Options for lethal, toxic and sub-zero fluid services plus process control and high flow requirement
