Features of quantitative valve: the quantitative valve is composed of measuring body, reversing body and other components. It adopts the principle of volumetric quantitative, with accurate quantitative.
Convenient adjustment and simple control. The valve is widely used in electronics, machinery, pharmaceutical, packaging, furniture, food, construction and other industries.
1. A ventilation pushes the piston rod upward, and the medium enters the upper and lower ends of the quantitative piston through port P. since the lower section of the quantitative piston is larger than the upper section.
The oil pressure pushes the quantitative piston upward to fill the cavity.
2. B ventilation pushes the piston rod downward, the oil inlet port P is closed with the lower chamber of the quantitative piston, and the lower chamber of the quantitative piston is connected with the oil outlet port t.
The medium enters the upper end of the quantitative piston through port P, and the oil pressure pushes the quantitative piston downward to push out the medium in the lower chamber of the quantitative piston, so as to realize quantitative oil discharge.
