Mitsubishi 150# servomotor The GVSM has a check valve that relieves between the chambers on either side of the piston. What is it for? I was told this design is similiar to WH

It looks like it would slow down quick closing GVs! but that don't make sense. pressure under the piston and draining above the piston would have the pressures in the direction for the relief to lift
what do you think?

Best of luck!

Yes the GVSM is double acting (UP to CLOSE), the drawing shows that this valve would relieve the pressure on the lower side of the piston to the upper side of the piston. the spring setting also sees the upper piston side pressure. I can observe that the relief will limit the closing force of the GVSM. I would think that would also reduce the closing velocity.
So I have derived what the drawing indicates it will do, but is that what the design was suppose to do and why would a designer do it?
Also, can anyone open the first files that are pdfs? (I can't)
