API 6D Expanding Gate Valves
Brand: Ranger Valve America LtdThe 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
