GB Gate Valve
Overview:
Cast steel gate valve has a small fluid resistance, sealing surface impact erosion is small, does not change the medium flow direction, do not disturb the flow, small pressure drop, etc., applicable pressure, temperature range, is a common cut-off valve, widely used in petroleum, chemical, thermal power plants and other oil, water vapor pipeline to connect or cut off the medium in the pipeline.
Specification:
Size: DN 15~1200
Pressure: PN 10~160
Body: cast steel, carbon steel, stainless steel
Features:
- The product structure is reasonable, reliable sealing, excellent performance, beautiful shape.
- Co-based hard alloy is overlaid on the sealing surface, with good wear resistance, corrosion resistance and anti-scuffing performance and long service life.
- The valve stem is tempered and surface nitride treated, with good corrosion resistance and anti-scuffing.
- The nominal pressure≥15.0MPa(Class900)The cavity adopts self-tightening sealing structure, the sealing performance is enhanced with the increase of pressure to ensure the sealing performance.
- The valve is equipped with an inverted sealing structure for reliable sealing.
- The material of parts and the size of flange and butt welding end can be reasonably matched according to the actual working condition or user requirements to meet various engineering needs.
