The high-quality standard air cylinders is used to adjust the medium flow, pressure and hydraulic. According to the adjustment part of the signal, automatic control valve opening, so as to achieve the media flow, pressure and hydraulic adjustment. JELPC Automation Components sub-electric control valve, pneumatic control valve and hydraulic control valve. Control valve by the electric actuator or pneumatic actuator and control valve composed of two parts. The electric control valve is usually divided into two types: single-seat type regulating valve and straight-through two-seat regulating valve. The latter has the characteristics of large circulation capacity, unbalanced operation and stable operation, so it is usually especially suitable for large flow, Leak less occasion.
The flow capacity Cv is one of the main parameters of the selection of the Japan Series Cylinder. The circulation capacity of the control valve is defined as: when the pressure of the valve is 0.1MPa and the fluid density is 1g / cm3, The flow rate of the diameter control valve, known as the flow capacity, also known as the flow coefficient, expressed in Cv, the unit is t / h, the liquid Cv value calculated by the following formula.
