Manufacturer for Hydraulic Valves

2 months ago in early February, AAK customized a PV72-30AM Proportional Valve Assembly for a European customer.

The valve assembly includes a HydraForce solenoid operated, pressure compensated, spool type, normally closed, proportional priority flow control valve PV72-30AM-0-N-12DG, and a HydraForce CV08 series Check Valve, assembled to an aluminum block. This is just very similar to a valve and block assembly that we shipped to a customer in Russia before, and we finished it in 15 days and a/f'd it to customer by end February.

2 weeks ago in early April, we received email from customer that they are happy with test result and are willing to place order for another batch – part of them to be shipped by air and remaining to be shipped by railway or sea. This... Читать дальше (Содержит видео)

PV72-30AM Solenoid-Operated Proportional Valve Assembly

Chinese Hydraulic Screw-in Cartridge valve manufacturer AAK often receives various questions from overseas customers, some of which even come from college students conducting academic research. Today, we will once again introduce the main materials used for seals in hydraulic screw-in cartridge valves, as well as their respective characteristics:

1. Rubber Sealing Materials

1) Nitrile rubber (NBR)

- Excellent oil resistance, suitable for conventional hydraulic oil environments, with a working temperature range of -40 ℃ to+120 ℃.

- Mainly used in static sealing scenarios, such as O-rings and some combination seals

2) Fluororubber (FKM)

- High temperature resistance (up to 200 ℃), chemical corrosion resistance, suitable for hydraulic oil containing... Читать дальше (Содержит видео)

How to Select the Seals for Hydraulic Cartridge Valves

For each hydraulic Screw-in cartridge valve, hydraulic cartridge valve manufacturer AAK conducts very strict quality inspections from raw materials to shipment, and the inspection processes is roughly as follows:

1. Raw material inspection

The raw material manufacturer provides material analysis reports to hydraulic cartridge valve manufacturer AAK, and AAK regularly entrusts third-party organizations to conduct material analysis.

2. Inspection of purchased finished products outside

For some components that hydraulic cartridge valve manufacturer AAK purchased outside, such as the coils, O-Rings, TPE back-up rings etc, the component manufacturer provides material reports and inspection reports to AAK, and AAK conducts size sampling before storage....

Steps for Quality Inspection to Hydraulic Cartridge Valves

AAK customizes hydraulic manifold blocks for customers in multiple countries, including Germany, the United States, Russia, and Israeli military clients.

We strictly control the selection of materials, processing techniques, surface treatment, cleaning, and inspection to ensure the reliability and longevity of hydraulic manifold blocks like below:

1. Materials and Pretreatment

1) Material Selection

 The valve block material should have a dense structure and be free of defects such as sand holes and interlayers. If necessary, non-destructive testing should be carried out.

 If forging blanks are used, they need to undergo normalizing treatment to eliminate internal stress and non-destructive testing.

2) Pretreatment

 Cast iron or... Читать дальше (Содержит видео)

5 Tips to Guarantee Functionality & Durability of Hydraulic Manifold Blocks

Before CNY, we received an inquiry from a European customer for a Valve Assembly.

The valve assembly includes a HydraForce solenoid operated, pressure compensated, spool type, normally closed, proportional priority flow control valve PV72-30AM-0-N-12DG, and a HydraForce CV08 series Check Valve, assembled to an aluminum block. This is just very similar to a valve and block assembly that we shipped to a customer in Russia before, and we can finish it in 20 – 25 days.

The customer confirmed the order with us before CNY. Because this assembly is urgently needed for an application, once our factory is reopened from holiday in February 10, 2025, we expedited the process and finished it in 15 days. Today, it was picked up by customer and air freighted by FedEx... Читать дальше

HydraForce PV72-30AM Solenoid-Operated Proportional Valve Assembly

In recent months, we received the inquiries for HydraForce hydraulic solenoid cartridge valve SV12-P23A-0-U-24EG-M3 from several customers.

This is a solenoid-operated, 2 way, normally open, poppet-type, screw-in hydraulic cartridge valve, designed to function as a load holding or blocking valve in applications requiring low internal leakage. It has the Position Indicator Switch with Restricted Flow, and with Neutral Sense, DT04-4P, Dual Output NC/NO.

Currently, only a few of the hydraulic cartridge valve manufacturers in China can offer this option and the price is very high. At the repeated requests of the customer, AAK purchased the original product from overseas, and is in developing it. It is difficult and may take a long time.

China’s cartridge valve exports increase in 2025

Today, we'd like to introduce a hydraulic counterbalance valve, equivalent to Danfoss 1CE30.

This model was developed for a customer in Brazil last July. Besides Brazil, till now, it has been shipped to Russia and India. Customers are very happy to have found a supplier with expected quality at a reasonable price.

Here are the advantages of this counterbalance valve:

* Economical and suitable for simple jacks.

* Quick and easy field installation.

* Can be used interchangeably with pilot one-way plugs of similar size.

* The quality of this valve is benchmarking SUN, but price is much cheaper.

* The service life is 2 times that of domestic hydraulic cartridge valve manufacturers in China

AAK is posting new Hydraulic Relief Valves equivalent to SUN RPEC8, RPGC8, RPIC8, RPKC8 series

Today, we'd like to introduce a series of hydraulic relief valve, equivalent to SUN RPEC8, RPGC8, RPIC8, RPKC8 series.

These valves are normally closed modulating elements that incorporate an integral pilot control cavity. They are balanced piston design.

The RPEC8, RPGC8, RPIC8, RPKC8 pilot control cavity will accept any T-8A pressure control cartridge. When the pressure at the inlet (port 1) reaches the pilot control cartridge's setting, the modulating element starts to open to tank (port 2), throttling flow to regulate the pressure. The pilot cartridge's setting determines the difference in pressure between port 1 and port 2. With the -8 control option,... Читать дальше (Содержит видео)
