IFR12-33 Flow Fregulator Pressure-Compensated Valve

Name: IFR12-33 Flow Fregulator Pressure-Compensated Valve
Brand: Wuhu Inno Hydraulic Technology Co., Ltd.

This valve features pressure compensation functionality, allowing it to maintain a consistent flow rate even when the system pressure fluctuates. By automatically adjusting the valve's opening, the IFR12-33 ensures that the desired flow rate is maintained, regardless of changes in hydraulic pressure. This feature makes it ideal for applications where a consistent flow rate is critical, such as in precision machinery, process control systems, and mobile equipment.

3. Quiet, modulated response.

4. Industry common cavity.

Operation Symbol of IFR12-33

The IFR12-33 maintains a constant flow rate from ③ regardless of load pressure changes in the system downstream of ③, or in the bypass leg at ②. Reverse flow (③ to ①) doesn't bypass the control orifice. The regulated flow increases from closed to fully open, with counter-clockwise rotation of the knob.

Note: When used as a bypass flow control in applications where the priority flow port will be blocked by external valving, the bypass pressure drop will increase unless a small amount of leakage is provided for the priority port. Consult Inno.
