Collaboration between seismic-resistant joints and B122.
The "Seismic Resistant Pipeline Compatible GX Type B122 Metal Seat Shut-off Valve" is a metal seat shut-off valve equipped with inlet ports equivalent to GX type irregular pipes on both sides. The performance as a metal seat shut-off valve is based on the proven JWWA B 122 standard (Type 3 - 10K), and it has passed the type tests under the same standard conditions for all nominal diameters. Furthermore, by combining a robust valve box reinforced for strength with a flexible valve body, it maintains water-tightness that withstands bending and tension caused by earthquakes while leveraging the seismic resistance of the "GX type." 【Features】 ■ Meets seismic standards (detachment prevention test, bending strength test) ■ The outer surface of the valve box is treated with zinc spraying and sealing to form a corrosion-resistant layer ■ Durable with a metal valve seat, providing excellent water-tightness ■ The effective length is the same as that of the GX type soft seal shut-off valve (dual inlet type) *For more details, please download the PDF or feel free to contact us.
