Fixed ball valves

Fixed ball valves mainly refer to the valve core, that is, the structural form of the valve ball. In addition to the floating fixation of the valve seats on the left and right sides, the upper and lower valve stems also have fixed support. Structurally speaking, the sealing form of fixed ball valves requires higher requirements than floating ball valves. In addition to the sealing surfaces of the ball valve core and the left and right valve seats, the accuracy of the upper and lower valve stems also needs to be taken into account. The fixed ball valves produced by Shanghai Meiyan Yi Pump Valve are more suitable for large-diameter and high-pressure working conditions, especially for large-diameter American standard fixed ball valves, which have particularly stable quality. The main working principle is that the valve's plug body is a spherical body with a circular through-hole or channel passing through its axis, which can be opened, closed or adjusted by rotating 90 degrees.
