描述

The Cast Steel Bidirectional Butterfly Valve is a flanged, offset-disc butterfly valve designed to seal equally well against pressure from either side. It can be installed without regard to flow direction and used where flow reverses, making it a versatile isolation valve for industrial water, oil and gas lines.

技术规格:
  • 压力等级: PN16 / PN25 / PN40
  • 尺寸范围: DN50 – DN1200
  • 适用介质: Water, steam, oil, gas, air
  • 工作温度: -29°C至200°C(软密封)/最高425°C(金属密封)
