Brand: Ranger Valve America Ltd
Add Product to My Catalog

The RANGER expanding gate valves are made to serve petroleum, gas, chemical, water, and slurry applications with an emphasis on reliability, safety, and positive shut-off.
Features
  • Sizes from NPS 2” to 30” (DN50 to DN750)
  • Class 150 to 2500 (PN20 to PN420)
  • Operating temperature -196°C to 593°C (the range of service temperature may vary for different materials)
  • The sealing faces of the valve seat and valve face are hard-faced to improve the erosion resistance and extend the service life of the valve
  • SS+graphite (spiral-wound) or metallic seal (RTJ) or pressure seal bonnet is used to provide a reliable bonnet seal
  • Rising stem position for visual indication of disc position
  • The valve stem thread is isolated from the pipeline media to reduce corrosion
  • The expanding gate design reacts to thermal cycling while maintaining a seal.
  • High CV due to full port design
  • Optional Class A sealing testing available to meet the fugitive emission standard ISO 15848 FE
