Hydraulic solenoid refers to an actuator create suction to pull and push valve core, thus control the direction of liquid flow, switch, flow, pressure, etc. Hydraulic solenoid is a vital component of hydraulic valves. In the control system, hydraulic serves as a connecting link between the preceding and the following. Hydraulic solenoid converts electrical energy into mechanical energy and dive the hydraulic valves.

Technically, a hydraulic solenoid consists of solenoid coil and iron core, they are usually supplied in full set or supplied separately on the market. How to choose the proper one among a host of hydraulic solenoid suppliers? With 70 years’ experience, KaiDi sums up a series of  hydraulic solenoid buying guide for you to choose better cost-effective solenoids. More solenoid specifications at solenoid buying guide Ⅱ: how to choose a solenoid?

Applications

As a basic electronic component, hydraulic solenoid has wide application fields. Many mobile hydraulic systems need hydraulic solenoid, such as construction and agricultural machinery, Forest technology, Wind, oil & gas, Trucks, Municipal technology, Industrial applications (injection molding machines, tooling machines, etc.).

HYDRAULIC SOLENOID APPLICATION

According to different applications, hydraulic solenoids can be classified into several types, including on-off solenoid, proportional solenoid, explosion-proof solenoid, displacement sensor and so on. All these hydraulic solenoids play various roles in hydraulic system.

How to choose suitable hydraulic you need? Firstly, figure out where hydraulic solenoid would be used. And then, what you need to do is look for the hydraulic solenoid with relative function. For example, explosion-proof solenoid is designed for equipment that must have the function of explosion proof; on-off solenoid for on-off valve; proportional solenoid for proportional valve.

One thing to note is that hydraulic solenoid for branded valves, such as Yuken, Rexroth, Vickers, Parker, ATOS and etc. Determine if the production and processing capacity of corresponding brand solenoid available.

Models

Except the application, every kind of hydraulic solenoid has a lot of models and specifications. Before buying, learn the common parameters of hydraulic solenoid will help to choose proper product. Here are some key parameters of hydraulic solenoid suggested by KaiDi:

Power system: AC or DC

Rated voltage: 12V / 24V / 110V / 220V

Valve size: NG6 / NG10 /NG16 /NG20

Work system: uninterrupted duty, intermittent periodic duty, etc.

Service life: 10 million / 6 million times

There are other parameters are worthy to note, including protection grade, rated stroke and special parameters for special application. In conclusion, a thorough knowledge of product is conducive to buy better hydraulic solenoid.

Certifications

Industrial Certification is a major consideration of solenoid buying. To meet different requirements, there are a variety of certifications on the market. For hydraulic solenoid, universal certifications include ISO, CE, UL, and etc. Besides, according to your actual demand, check the certifications of hydraulic solenoid manufacturer or supplier.

Quality control

As the saying goes, quality above all else. It is necessary to put quality as the first consideration. Except professional certifications, full quality inspection equipment and inspection procedures are also important. As for hydraulic solenoid, solenoid coil is a core part of solenoid. The working life of coil directly affects hydraulic solenoid. For instance, a hydraulic solenoid supplier who has complete coil test equipment and quality inspection procedure will be more convincing.

Service

The other important factor next to product quality is customer service. How to select more proper one between two good hydraulic solenoid suppliers with equal product quality? The answer is service. Common services for solenoid like shipping, sample, quality warranty, etc. Take KaiDi as an example, we provide following services for each client:

  • We supply free samples for part of products.
  • One year quality warranty promised.
  • Customization service available. From design to installation.
  • OEM available.
  • Fast delivery guarantee.

In addition to these factors mentioned above, production ability and experience in handling relative order are both considerable. KaiDi summaries only hydraulic solenoid buying guide based on almost 70 years’ experience in manufacturing hydraulic solenoid. We are aim of meeting full satisfaction of customers, if you have any concern about hydraulic solenoid or relative service, welcome to contact!
