Throttle NV08-20B Flow control valve Hydraulic valve threaded cartridge valve

      A throttle valve is a valve that controls the flow of fluid by changing the throttle section or length. The throttle valve and the check valve can be combined into a one-way throttle valve by connecting them in parallel. Throttle valve and one-way throttle valve are simple flow control valves. In the hydraulic system of quantitative pump, throttle valve and relief valve are combined to form three throttling speed regulation systems, that is, inlet throttling speed regulation system, return throttling speed regulation system and bypass throttling speed regulation system

       First, hydraulic:1, the main pump (hydraulic pump), usually called the large pump, is to supply oil to the entire hydraulic system, in short, to produce pressure to provide action for the excavator.2, the pilot pump, generally for the gear pump, the current excavator pilot pump and the main pump are connected together to provide the pilot oil for the action of the excavator (that is, the oil required for the operation of the handle of the excavator).Second, the engine:1, the oil pump provides lubricating oil to the lubricating mechanism of the engine, so that the engine life is longer and the work is more stable.2, the hand oil pump, located in the engine fuel injection pump pan, in the low pressure oil circuit of diesel.3, injection pump, there are two kinds of electric injection and direct injection, to provide high pressure fuel for the engine action, so that the fuel into the cylinder combustion chamber.4, water pump, generally located at the fan end of the water-cooled engine, the role is to provide cooling water for the engine cooling system, so that the antifreeze can be circulated, so as to ensure the service life of the engine.
