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:

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.
