IFR12-33 Flow Fregulator Pressure-Compensated Valve

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.

INNO China hydraulic valves are widely used in hydraulic systems to control the flow, pressure, and direction of hydraulic fluid. They are essential components in various industries, including construction, agriculture, oil and gas, aerospace, and automotive. Hydraulic valves are used in applications such as cranes, excavators, bulldozers, tractors, aircraft, and trucks. They help to regulate the movement of machinery, prevent damage from excessive pressure or flow, and improve overall system efficiency.
