DESCRIPTION
V230Y Self operated (Micro) Differential Pressure Regulating ValveProduct Overview:
V230Y11/12 type self operated differential (micro) pressure regulating valveIt is an energy-saving product that does not require external energy and utilizes the energy in the process pipelinePressure changes and signalsCompare and balance the force of the regulated medium with the output force of the actuator to achieve a determined pressure and differential pressure value. It is mainly used in various industrial furnace gas combustion systems to control the mixing ratio flow of fuel A and B to achieve ideal combustion conditions. The self operated differential pressure regulating valve can be used in the sealing oil system of steam turbine generators to ensure the normal and safe operation of the generator set and improve power generation efficiency. Can be used forGas, natural gas, liquefied gas, petroleum gas, nitrogen gasReduce pressure and adjust micro pressure of various industrial gases. Self operated differential pressure regulating valve can also be applied toPetroleum, chemical, metallurgical, pharmaceuticalDuring the process of waiting for the industrial sectorDifferential pressure or micro pressure, balance systemAutomatic adjustment.
