Describe
Stainless steel American standard cut-off valve features:
1. The design and manufacture of the product meets the requirements of the American national standard ANSI B16.34, British BS1873 and other foreign advanced standards.
2. The outer shape of the valve is barrel-shaped or streamlined, the shape is beautiful, the shape of the flow channel is straight-through, and the fluid resistance is small.
3. The closing part (valve) and the sealing surface of the valve seat are sealed by a cone surface, which has small closing force, erosion resistance and reliable sealing.
4, the valve seat can be a replacement valve seat, can be arbitrarily combined with the sealing material of the closing part to meet the working conditions and extend the service life.
5, large-diameter, high-pressure shut-off valve according to the need of the closing force of the valve stem transmission mode is lifted, and equipped with a rolling bearing type with a percussive handwheel to reduce the closing force.
6. The materials of the main material, internal materials, fillers, gaskets and fasteners can be reasonably combined according to user requirements or actual working conditions.
