sporlan valve

[Ralph L. Fullenwider]

Mike:

The closing mechanics of the Sporlan is simply a spring return applying
pressure to the diaphragm when 12 vdc is removed from the coil. Yes it can
become weak and usually requires a new rebuild kit, in this case, or so I
have found in the past. But it should not be affected by any pressure, have
you check to be sure there is no sand in the valve base that can effect the
throw of the piston with the rubber seal on one end and return spring on
the other?

Safe travels,

Ralph, I took the valve apart and cleaned it. I looked at some old Sporlan
parts i had taken out of another valve. The spring on the plunger is longer on
the old part. I ordered two rebuild kits from Steven. Hope to get them soon.
Hope to see you and Charlotte at the Christmas Rally. Mike McMahan 96 42'

Had that problem 4 months ago.
Had Stephen ship me the rebuild kit and the problem was solved.

Sounds like you have the problem all but done then.

Yes, Charolette and I will be at the LSB X-Mas Rally, we will be in space
17. Looking forward to seeing you and Barbara as well.
