API 594 Dual Door Wafer Check Valves

Brand: Ranger Valve America Ltd
Request Information
RANGER’s Dual Door Wafer Check Valves reduce or eliminate line shock when flow is reversed, and provide cost savings when compared to conventional swing-check valves.
Features
  • Sizes from NPS 2” to 48” (DN50 to DN1200)
  • CLASS 150 to 2500 （PN20～PN420）
  • Operating temperature -29℃ to 593℃ (the range of service temperature may vary for different materials)
  • The sealing faces of the valve seat and valve clack are built-up welded with hard alloy to improve the erosion resistance and extend the service life of the valve.
  • Short closing travel of valve clack, and small impact at valve closing; short structural length, most suitable for positions with limited mounting space
  • Suitable for medium backflow prevention in pipeline or device
  • Built-in pin roll, without external leakage point
  • Due to the loading of the spring, the valve clack can move flexibly without jamming and has a good sealing performance.
