Hydraulic Directional Control Cartridge Valve 1 More Function 3 Advantages - China

price: 60.00 Dollar US$

AAK Hydraulic Directional Control Cartridge Valve has 1 more function than HydraForce, and 3 advantages Chapin is from Canada and has purchased hydraulic cartridge valves in Ningbo for 5 years.

At the beginning of this year, their hydraulic cylinder needed hydraulic directional control cartridge valve.

He found a hydraulic directional control cartridge valve manufacturer in Ningbo to test the sample, but it was not successful.

When the external load of the oil cylinder suddenly changes, the response of the hydraulic direction control cartridge valve is slow, and the shunt accuracy cannot keep up with it, which is not synchronized with the execution of the oil cylinder.

According to the feedback from the original manufacturer of the hydraulic directional control cartridge valve, this is the standard model of HydraForce hydraulic directional control cartridge valve.

Now the function does not match, so he can only replace it with other model of HydraForce standard parts.

Chapin was a little confused.

Chapin contacted AAK under the introduction of his friends, and told us the dilemma of the hydraulic directional control cartridge valve sample at present, and asked whether AAK could improve the function of the original hydraulic directional control cartridge valve to match the cylinder execution synchronization? 2 days later, AAK's plan was ready.

Chapin paid the development fee the next day and asked for AAK samples.

After 40 days, AAK sent the samples of hydraulic directional control cartridge valves.

Yesterday, Chapin informed us by email that the test run was successful.

After replacing with the AAK hydraulic directional control cartridge valve, the cylinder execution was synchronized and the stability was improved.

The prototype has been delivered to the customer.

AAK hydraulic directional control cartridge valve has fast response, high shunt accuracy and stability.

These 3 advantages are attributed to the optimization of 3 structures based on the original hydraulic directional control cartridge valve.

1 - On the main valve sleeve wall of the hydraulic directional control cartridge valve, there are external main oil ports, 2 external load oil ports, locating pins, floating steel balls, and grooves corresponding to the through-hole.

The floating steel balls float between the bottom of the locating pins and the grooves.

This ensures that the internal load oil port and the external load oil port are always connected, which can realize the static two-way stroke correction of the two load cylinders, and remove the obstacles for synchronization.

2 - The spool valve of the hydraulic direction control cartridge valve is sleeved with an inner main oil port and an inner load oil port, and the throttling channel connected with the inner main oil port is on the valve spool.

The throttling channel has a fixed orifice and a variable orifice which are connected with each other.

The fixed orifice is connected with the inner main oil port.
