    How to convert Valve Pressure PSI, BAR and MPA?

    PSI and MPA conversion, PSI is a pressure unit, defined as the British pound/square inch, 145PSI = 1MPa, and PSI English is called Pounds per square in. P is a Pound, S is a Square, and i is an Inch. You can calculate all units with public units: 1bar≈14.5PSI, 1PSI = 6.895kpa = 0.06895bar Europe ...

  • Flow characteristics of regulating valve

    The flow characteristics of the control valve mainly include four flow characteristics: straight line, equal percentage, quick opening and parabola. When installed in the actual control process, the differential pressure of the valve will change with the change of the flow rate. That is, when the...

  • How regulating valves, globe valves, gate valves and check valves work

    Regulating valve , also called control valve, is used to control the size of fluid. When the regulating part of the valve receives a regulating signal, the valve stem will automatically control the opening and closing of the valve according to the signal, thereby regulating the fluid flow rate an...

  • The main difference between pressure reducing valve and safety valve

    1. The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure through adjustment, and relies on the energy of the medium itself to automatically maintain a stable outlet pressure. From the point of view of fluid mechanics, the pressure reducing va...

  • Summary of the differences between globe valves, ball valves and gate valves

    Suppose there is a water supply pipe with a cover. Water is injected from the bottom of the pipe and discharged toward the pipe mouth. The cover of the water outlet pipe is equivalent to the closing member of the stop valve. If you lift the pipe cover upward with your hand, the water will be disc...
