Orifice Check Valve is used on a fluid system which needs normal operation speed on one direction and reduced speed in other direction. The figure…
Hydraulic restrictor valve is used to reduce the fluid flow rate which decreased the actuator speed movement. There are two main type of restrictor, fixed…
In a hydraulic meter-out circuit the flow control valve is installed on the cylinder return line. The cylinder speed will be controlled through its discharge…
In a hydraulic meter-in circuit flow control valve is installed in the pressure line. Before the fluid flows to the cylinder, it’s metered through this…
On manual steering system, the gear box will multiplies the steering wheel torque input to create greater torque to the steering shaft. The steering shaft…
Needle valve has the same working principle with globe valve; the most obvious different is needle valve uses long tapered point at valve stem end…
Hydraulic pressure regulator is typically called unloading valve. There 2 main parameter on the unloading valve, there are opening pressure and closing pressure. For example,…
The figure above illustrates a pressure controlled sequence valve working principle. The spring tension which holds the piston can be adjusted to obtain opening pressure.…
On large hydraulic valve the force needed to operate the valve also increases. If the force is too large for solenoid or manual operation, then…
