What is the difference between a wear-resistant ball valve and a hard-sealed ball valve

What is the difference between a wear-resistant ball valve and a hard-sealed ball valve?

In terms of internal structure, it is different. Generally speaking, wear-resistant ball valves must be hard-sealed ball valves. Hard-sealed ball valves only mean that the sealing pair of the ball valve is a metal-to-metal seal, and the surface of the sealing pair is hardened by different processes. The wear-resistant ball valve not only considers the hardening and wear-resistant treatment of the sealing pair, but also achieves wear-resistant in the valve cavity and the direction of the medium flow.

Introduction to Zhejiang wear-resistant ball valve

Wear-resistant and corrosion-resistant ball valves have related problems such as a large contact area between the seat seal ring and the ball core, insufficient switch sensitivity, and low utilization of upper and lower stem materials. A new type of wear-resistant and corrosion-resistant ball valve is designed. Through improved design, the defects during casting are overcome. The purpose of energy saving, material saving and environmental protection has been achieved. The sealing quality of the ball valve has been improved, and the reliability has been improved. It has been well verified in actual operation and has achieved the expected effect. It has a wide range of promotional value and use value.
