The Type 84 valve features a cartridge assembly design that applies uniform spring pressure, resulting in secure seat sealing and leak-tight performance.
A question arose regarding the pressure drop to use when sizing a control valve. Assuming a system that has already been designed, the sizing pressure cannot be arbitrarily assigned, but the values of ...
Figure 2 shows the instantaneous pressure as liquid moves through a control valve. The inlet and outlet cross-sectional areas of a valve are much larger than the control area, such as the cage or the ...
