| LDK Constant Flow Control¡¡Valve integrate reducing valve and throttle valve in a single body. It is widely used to oil industry, chemical industry, water treatment indurstry and other fluid controlling fields. No matter what the inlet and outlet pressure changed, this control valve can keep the flow at the setting value. | |
 |
| Suppose the inlet pressure of this control valve is P1.After flow through the reducing valve, the pressure reduce to P2. After flow through the throttle valve, the pressure reduce to P3.The P2 and P3 feedback to the valve core of the throttle valve. When the the pressure of P1 and P3 changing, the feedback preesure will keep the inlet pressure and outlet pressure balance to a fixed value. In this way, it keep the setting flow rate value no change with the P1 and P3 .
