Flow is controlled by the principle of throttling, and distributed according to flowing capacity (flow constant). Meanwhile, the measurement device in the lubricating system with near, distant, high, low, horizontal or vertical installation have identical outlet flow. With long service life, the rubber sealing parts of the proportional one-way joint is coated with copper sleeve (except sealing face) to prevent expansion and aging of rubber sealing parts.
Sensitive action and smooth oil drain: taper spring is used for one-way valve with proportional joint to ensure that action of the measurement device is agile and smooth to prevent reverse flow of oil.
Flow ration: flow of the same model shall be changed with change of environmental temperature and oil viscosity in use.
