The ball valve made of solid components has high durability and can function perfectly even after being idle for a long time. It has a ball made of brass, stainless steel or chrome plated brass, which is embedded in the conduit. The top of the ball is a lever, which can only shake a quarter of a tur
1. Bypass valve: the ball valve is generally opened by static water, so the bypass valve is set for flat pressure first, that is, both sides are filled with water;2. Air valve: when filling water, remove the air and take the float to close the valve by itself; During drainage, make up air and the po
Compared with other types of valves, pneumatic ball valve has the advantages of angular stroke output torque, rapid, stable and reliable opening, wide application, and the following advantages:1. The thrust bearing reduces the friction torque of the valve stem, which can make the long-term operation
1、 Wear resistance; Because the ball valve core of hard seal ball valve is alloy steel spray welding,and the sealing ring is alloy steel surfacing, so the hard sealed ball valve will not produce too much wear when opening and closing.2、 Good sealing performance; As the sealing of hard sealed ball va
Ball valve came out in the 1950s. With the rapid development of science and technology and the continuous improvement of production process and product structure, it has rapidly developed into a main valve in just 40 years. In western industrial developed countries, the use of ball valves is increas
Ball valve is a valve whose opening and closing parts (ball) are driven by the valve stem and rotate around the axis of the ball valve. It can also be used for fluid regulation and control. Among them, there is a strong shear force between the V-shaped ball core of hard sealed V-shaped ball valve an
