HAWE online product configurator

Dzyanis August 30, 2022 0 Articles hawe, valve 977 Views

It was always a challenge for us to configure HAWE proportional multi-section valves such as PSV, PSVF, etc. And I asked many times our vendor about something like an online configurator for HAWE products. You know, the best part of using tools like this is preventing errors, especially in so complicated configurations with a bunch of options. But the best what they suggested is to use HAWE CD with a very old configurator or just send requests to them. What actually is not a time-saving solution.

Here you can directly configure products, access product data, make a customer service request or program your machine control. You can also communicate directly with your contact person via the customer portal. We are looking forward to your feedback and requests in order to continuously optimize and expand our online service offer.
Your HAWE Team

So, what you need to start using product configurator is to make an account in HAWE Customer Portal first:

https://customerportal.hawe.com/

And now, almost for each product at their website you get a link to the “TypeMan+” platform, where you can configure the product. For example here is the link to PSV valve configurator:

In addition to the product configurator, you get a spare part catalogue, 3D catalogue and other benefits. Make your life easier!

Parker 689B series valve obsoleted

Parker 689B series valve

So, Parker continues to discontinue nice products 🙂

Now they obsoleted valves 689B series…

It is hard to find panel-mounted hydraulic push button valves. Most of the push-button valves are cartridges and to be assembled with a body. Body has mounting holes and some design of brackets is required to mount to assy body + cartridge to the panel.

The benefit of the valve 689B series was in mounting holes at the top, which lets easy mount to the panel.

In most applications, I easily replaced this type with an electrical button that operates a simple solenoids valve. But some specific applications require simple hydraulic manual control (some equipment at the rig, where the electrical-over-hydraulic control is not allowed by safety reasons.)

So, the question to you guys, can you advise an elegant replacement for this valve?

Updates:

Jan 29, 2020 By the advice of couple vendors I ‘m going to try to use Doering push-button valve as a replacement:

Doering push-button valve

Different spacers can be used, but I’m going to proceed with custom spacers to make button hight as low as possible over the panel. Not really elegant solution but time is limited and I need to make a decision. I will update this pose as soon as the panel is done to show how the solution looks like.

SUN Hydraulics – delivery time issue

Dzyanis October 28, 2019 2 Articles SUN, valve 737 Views

SUN delivery issue Working on the design of new projects I like to involve SUN Hydraulics valves and use them a lot. They are not expensive, pretty reliable and have uncredible understandable paper and online catalogs.

All these major benefits coming to naught as soon delivery time even of very wonderfull products makes impossible to use them in projects. This is exactly what going on these days.

Today I got a quotation from a local vendor for the valve FDEA-LAN with delivery time 31 weeks!!! It is longer than my project needs to be completed!

Helios Technologies (formerly known as Sun Hydraulics) has three facilities in the Americas, two in Europe and already three in Asia-Pacific (one more plant in China has been opened this year). But this fact doesn’t help to provide SUN valves faster.

Because the company, where I’m working now, has fillies in Europe we know the issue with the SUN product delivery time is currently common for the whole world. There no any comments from SUN and its parent Helios at their websites and I see the delivery time is increasing every month.

Therefore, I’m seriously starting to think about solutions on how to proceed. Problem is a lot of manifolds that have already been designed in our projects use SUN cavities. And to re-design of these manifolds is a pain, you know why. I’m seriously thinking to use SUN clones to cover these positions. Currently, I dug the next manufacturers:

Winner Hydraulic. This is a manufacturer from Taiwan, but they do not have distributors in North America.
PressureBoss Hydraulics Inc. From their website is not clear what country their plant is physically situated. They have distributors in the US but not in Canada.

For new projects, I’m starting to look at Parker and Eaton cartridges. They have a pretty good assortment and actually last months I already used some of their valves as quick replacement options.

How you are dealing with SUN Hydraulic delivery issue?

Proportional valve control calculation. Part 2.

Dzyanis February 20, 2017 0 Articles cylinder, proportional, valve 977 Views

Part 2. Proportional control in the regeneration mode.

Fig.1. Regeneration mode schematic

The goal of the calculation is definition of a cylinder velocity at the current operating voltage at the valve’s solenoid.
For calculations we need to know: cylinder and valve parameters (take them from manufacturer catalog), values of forces at cylinder rod (load) and pressure drop at return line (can be assumed as zero if unknown).

Summary:
2.1. Regeneration mode schematic
2.2. Regeneration Mode: Cylinder extension calculation
2.2.1. Balance of forces at the cylinder
2.2.2. Spool lands ratio and pressure drops at the spool lands
2.2.3. Hydraulic cylinder extension. System pressure calculation
2.2.4. Flow through spool lands: max. and at current voltage
2.3. Hydraulic cylinder retraction calculation
