I ordered a rebuild kit for a Star Exhauster BB and am having problems getting a rubber rebuild kit for this valve. Does anyone have a rebuild kit?
If this valve can't be rebuilt, what options are available? The system was designed to function with the valve. It already has an accelerator on the system Sent from my Galaxy S®III -------- Original message -------- From: Brad Casterline <[email protected]> Date: 09/25/2013 8:20 AM (GMT-05:00) To: [email protected] Subject: RE: old 14.5k ecoh brass upright Maybe the push to change was to stop any K-Factor War between manufacturers. I have heard it said there was an RTI war and that is why the makers stopped publishing the RTI in the data, i.e., "this head activates the square root of X feet-seconds faster than this one so it has to be better". But with K-factors it is more noticeable because the numbers in the calc sheets are all 2 or 3 decimal places "accurate", so why shouldn't K be? -----Original Message----- From: Roland Huggins [mailto:[email protected]] Sent: Tuesday, September 24, 2013 4:50 PM To: [email protected] Subject: Re: old 14.5k ecoh brass upright I think it was the 99 edition when it was changed so it has been awhile.
