Proportional Hydraulic Control Solution

Finotek offers multi-proportional control solutions as per customer requirements, equipped with our cartridge valves or other brands to generate different function hydraulic control manifolds, it accurate controls the pressure, flow rate and fluid direction. The proportional control includes:
– Proportional flow control: Precise control the flow rate of hydraulic actuators.
– Proportional pressure control: Precise control the pressure of hydraulic actuators.
– Proportional direction control: Precise control the action of hydraulic actuators.

Proportional Flow Control Solution: Normal Working Requirement
Proportional-Flow-Control-Solution-Normal-Working-Requirement

1. Equipped in hydraulic actuators which requires normal accurate control.
2. Electro-proportional valve controls the speed of hydraulic motor
3. Pressure relief valve limits the output pressure of hydraulic pump
4. With Max. pressure 35Mpa, Max. flow rate:480L/min.

Proportional Flow Control Solution: Pressure Compensation
