Requirements and selection points of Manifold Block hydraulic valve manufacturers

What are the requirements of Manifold Block hydraulic valve manufacturers for hydraulic valves, and how to choose Manifold Block hydraulic valve? Next, manufacturers of Manifold Block hydraulic valve come to explain the requirements and selection points of Manifold Block hydraulic valve in detail.

 

Manifold Block hydraulic valve manufacturers requirements for hydraulic valves:

 

1. Good sealing performance.

 

2. Compact structure, convenient installation, debugging, use, maintenance, generality. Hydraulic station, hydraulic system, will use this valve,

3. Flexible action, reliable function, small impact and vibration when working.

 

4. Little pressure loss after oil flow.

 

Manifold Block hydraulic valve manufacturers product selection points:

 

1. Manifold Block hydraulic valves have the main advantages of small size, reliable operation, convenient maintenance and cheap price. When choosing, attention should be paid to the selection of normally open and normally closed type according to the process requirements.

 

2. The main control parameters of Manifold Block hydraulic valve manufacturers are size, nominal design pressure, allowable temperature range of medium, interface size, etc.

 

3. Manufacturers of Manifold Block hydraulic valve use electromagnet to push the valve to open and close. It is usually used in the two type control with the caliper below 40mm, especially for the converter to connect and cut off the gas path and liquid path.

 

The above is the sharing of requirements and selection points brought by Manifold Block hydraulic valve manufacturers. For more information about hydraulic valves, please pay attention to the official website of our company.

 

Manifold Block electromagnetic directional valve performance characteristics

 

I believe you do not know much about Manifold Block electromagnetic directional hydraulic valve. Today, hydraulic valve manufacturers come to talk with us about the performance characteristics of Manifold block electromagnetic directional hydraulic valve.

 

1. Reversing and reset time: it is generally stipulated that the time from the electromagnet to the end of the spool reversing is the reversing time of the electromagnetic reversing hydraulic valve, and the time from the electromagnet to the spool returning to the initial position is the reset time of the electromagnetic reversing hydraulic valve. Generally, the reversing time is not equal to the reset time, but roughly the same, the reversing time of the AC electromagnetic reversing hydraulic valve is about 0.01-0.03s, and the reversing time of the DC solenoid valve is about 0.02-0.07s.

 

2. Pressure loss: The pressure loss of Manifold Block electromagnetic reversing hydraulic valve is composed of two parts, flow loss and valve port throttling loss. Due to the small opening amount of the electromagnetic reversing hydraulic valve, the throttling loss is relatively large, and the pressure loss caused by the oil flowing through the electromagnetic reversing hydraulic valve is relatively large.

3, service life: the service life of the electromagnetic reversing hydraulic valve mainly depends on the working life of the electromagnet, in addition, the processing and manufacturing quality of the parts of the electromagnetic reversing hydraulic valve and the fatigue strength of the return spring also affect the service life of the electromagnetic reversing hydraulic valve.

 

4, the reliability of the work: the reliability of the solenoid reversing hydraulic valve mainly depends on the design and manufacturing of the valve, reduce the effect of various reversing resistance on the spool, while ensuring the machining accuracy of the valve body hole and the spool and other parts, in order to improve the reliability of the solenoid reversing hydraulic valve.

 

5, reversing frequency: the reversing frequency of electromagnetic reversing hydraulic valve is mainly limited by the characteristics of the electromagnet, the starting current of the AC electromagnet is more than 3 times higher than the current of the normal suction, often starting will aggravate the heating of the coil, the general allowable working frequency of the AC electromagnet is less than 60 times/min. Because the dc electromagnet is not limited by the starting current, the reversing frequency can reach 250 ~ 300 times /min, in addition, the reversing frequency can not exceed the limit of the valve reversing time, otherwise it can not complete the reversing process.

 

The above is the sharing of the performance characteristics of Manifold Block hydraulic valve manufacturers, to learn more about the solenoid directional hydraulic valve, please pay attention to the official website of our company.
