LKF series is a full range pressure compensated variable fow control valve, referred to as "flow control valve". We adjust the size of the orifice area through the rotation of the valve spool, independent of other port pressure changes. to maintain the fow at the set value. currently. we have two ootions for customers to choose from, with or without adjustable spring safety valves.
| The role of the flow control valve: It is used to limit the maximum flow of the steering oil pump, flow control valves and safety valves are generally Crafted inside the oil pump. The flow rate of the steering oil pump is related to the gear speed (and thus the engine speed proportional. |
|
| Steering oil pump is generally designed so that even when the engine is running at high speed, its flow can also ensure the maximum movement speed of the power cylinder piston required for sharp steering. | |
| At beginning, when the engine speed is high, the flow rate of the oil pump will be too large, resulting in excessive power consumption of the oil pump and low oil temperature. Flow control valve is to limit the maximum flow of the steering oil pump. | |
| Working principle: 1.At normal pressure, the piston moves to the right and the pressure relief hole is closed. Pressure relief valve do not work. 2.When the pressure is medium, the valve plug moves to the right and the spring compresses. The pressure relief valve opens, excess oil flows back through the pressure relief valve to oil port. 3. When the pressure is high, the pressure relief valve is closed and the piston moves to the left. The pressure relief hole is opened, and excess oil flows through the pressure relief hole to oil return port. |
