How to Reverse the Pinion in a Bray Pneumatic actuator

This video explains how to reverse the pinion inside a Bray pneumatic actuator. This change is made when the actuator needs to be mounted in a non-standard fashion, but still operate in the same manner.

Great video. This just helped me out a ton on a project that we're involved in. 169 actuated units and 10 had to have this done. Thank you for the video

dude, thanks for making this video, we have a ton of these things at our facility and when i rebuild them I always get my a$$ handed to me when putting the pistons back in. Thanks to your video and that little teeth skip trick the one I did today went smooth. thanks again

chris howton Hi Chris, I'm glad this video was useful. This is the first feedback we've received.

Tri-State Valve & Instrument, Inc. Thanks again, showed it to the rest of the guys in the shop, they found it very useful as well.

We have many of this actuator in different sizes here in morocco. This video really helps..

[@ikechinix9524]

Many thanks for the video. How about the spring cartridges on both ends? I didn’t see any when you dismantled the valve. I believe the valve should be a double acting position type.

These are a pain. The video really did help alot thanks

+Javier Sotero Hi Javier, no problem, I'm glad the video helped

[@Hewagej]

Nice video Thank you so match for share your video

[@CantizeSay]

you didn't put back the springs before inserting the end caps

Hello Sir, Have a good day. I have recently facing problem in a newly buying Siemens PS2(2wire, 4-20ma, 2 wire, without HART) smart positioner connect with my existing Single acting, air to open linear actuator(pneumatic control valve) having 20mm stroke when I am going to newly calibation. During commissioning this new positioner with existing control valve/actuator in initial condition its display shows P 85 and NOINI mode, at that time when if i press (+) and (-) button then the actuator totally doesn’t not move.only small clicking sound hearing inside the positioner and little air Release from actuating pressure line(Y1) of positioner , however pneumatic(4kg air pressure) and electrical(4ma , 24VDc) connection is ok there. Interesting matter is, if i place old existing positioner there then it easily move the actuator after pressing (+) and (- ) key in P85, NOINI mode. Is there any problem of lever setting or restrictor setting there.i don’t change any restrictor setting in this newly buying positioner during commissioning there.i am confused if there any setting required in restrictor at positioner during newly commissioning? I depreciating if anybody here who can advice me kindly please to fix this problem.

Why didn’t you put the springs in?

[@klyetry2527]

No springs, double acting.

[@duramax78]

Can anyone tell me what the main body on these are made of, also the ends and insides I have a few I’m scrapping, one small one like this and some bigger ones.

[@BingeDrifter]

Ummm can't you lift the actuator off the square drive and install it back one flat over on the valve shaft?

[@roadhog88]

Springs?

[@shivakumar-zw1gp]

How you aligned the piston with pinion ?
