The opening and closing part of the national standard cut-off valve is a cylindrical valve disc. The sealing surface is a flat or conical surface. The valve disc moves linearly along the center line of the fluid. The national standard cut-off valve is only suitable for full-open and full-close. It is generally not used to adjust the flow rate. It can be adjusted and throttled when customized. Application: Flange connection national standard globe valve is suitable for nominal pressure PN1.6 ～ 16.0Mpa, work ..
The insulation jacket of BJ45 DC insulation cut-off valve is welded between the two flanges of the valve. It is especially suitable for pipelines in the chemical and fertilizer industries. The jacket contains steam to prevent crystallization of the medium. DC type thermal insulation globe valve is widely used in petroleum, chemical, metallurgy, pharmaceutical and other systems to transport high-viscosity media that will solidify at room temperature. DC type:
