HCB balance cage valve control all kinds of high temperature and low temperature high pressure fluid, is a kind of pressure balance type regulator. Valve structure is compact, has S streamlined channel, also has an improved sleeve around the balance of fluid flow of fin, the loss of the pressure drop is small, large flow, adjustable range and flow characteristic of high precision, IEC534-2-1976 standard. HCB balance cage valve dynamic good stability, low noise, small cavitation corrosion. Regulating valve leakage is in line with the ANSI B16.104 standards. Regulating valve with spring more film or cylinder actuators, its compact structure, big output force
