1, the valve shell thickness exceeds the national standard GB, JB and ANSI standard data requirements, the main material chemical elements and mechanical properties meet the national standard requirements.Shell three - section structure design, solid shape, beautiful appearance.
2, the valve stem material chemical elements meet the requirements of the national standards, fine grinding, the surface by corrosion resistance nitriding or quenching treatment, ensure that the valve stem has good mechanical properties and corrosion resistance.
3, Built-in buffer compensation elastic washer, to ensure the stability of good tightness.And in the medium containing impurities, it is not easy to get stuck causing the ball to break.
4, all lining hard sealing surface contact ceramic ball valve all contact with the medium is structural ceramic material, its chemical stability plus high hardness (hardness HRA88 above, second only to the characteristics of metalstone).Therefore, ceramics have high compressive strength, high wear resistance, excellent oxidation and corrosion resistance, high temperature resistance and good heat insulation properties.
5, with accurate grinding technology and advanced mechanical equipment manufacturing production.The valve structure is simple, the flow channel is smooth, the medium flow resistance is small.Hard sealing ceramic inner parts, composed of six scientific and reasonable design, valve ball, valve seat surface contact processing, so that the ball and seat R and R closely combined, ball round high precision, good surface quality, so that the whole valve torque light, small resistance, sealing to zero leakage.
