Brand: Flowserve Durco
Request Information
The Durco G4 Sleeveline plug valve is engineered for use the most corrosive and difficult chemical services where drop-tight shutoff is an absolute requirement.

It offers the proven reliability of the plug/PTFE sleeve primary seal with a fluoropolymer diaphragm secondary seal.
Features
  • Dependable, tight shutoff and in-line seal adjustment from tapered plug design
  • Lower maintenance costs due to design that utilizes 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-energizing dynamic and static stem seal
  • Compatibility with a range of Automax actuators and other instrumentation
  • Options for lethal, toxic and sub-zero fluid services plus process control and high flow requirements
