ASME Ductile Iron Y strainer

Size Range: DN15-DN600

Pressure: 150LB

Body Materials: Ductile iron



  • High tensile strength, not easy to break

    The body is ductile iron,high level than national stanard.Tensile strength is 450Mpa,elongation is large than 10%,can not be broken easily when transport.

  • 304 screen is resistant to erosion and corrosion

    The screen adopts 304 steel plate punching, rolling, spot welding, mesh mesh can be customized according to customer requirements, DN200 and above size with reinforcement structure design, high strength of the screen, with erosion resistance.

  • Use graphite gasket to resist high temperature

    Sealing gasket made of graphite material, high temperature resistance, long service life.

  • Streamlined design, low fluid resistance

    The strainer adopts full size form and streamline design to reduce the fluid resistance coefficient of the strainer.The diameter and length of the screen increase, increase the effective filtration area of the screen, reduce the pressure loss.

  • Large cavity reduces pressure loss

    The valve cavity becomes larger, and the circulation area between the screen and the inner wall of the valve body is more than half of the flow channel area, which effectively improves the utilization rate of the mesh at the back of the screen.

  • Anti-rust with epoxy coating

    Both inner and out part is epoxy coating, the thickness is 250μm minimum,can prevent rust well,can be used in sewage system.
