GMK swing check valve is used to prevent back flow in the line. Flow is in a straight line through the valve resulting in minimal pressure drop. The disc swings into the open position as the media flows through the line. Back pressure in the line holds the disc in the closed position. Swing check valves may be installed in horizontal or vertical lines, but must be installed in proper relation to the media flow as indicated by the flow direction arrow marked on the body.
quick video of what I did to check my valve clearance and the tools you need hope you enjoy.
,,,,,, But first i’m going to build some intake and exhaust valves, cast iron heads with steel stems,,, No! wait,, we got to have a blueprint,, some country logic and a red felt pen, now we got a blueprint (I guess you could call it a redprint), let’s get on with the show, the valves in this series are needed for a McCormick Deering (IHC made by International Harverster Co)(yes the first head goes on the baling wire engine) 1 1/2 hp gas engine with a throttle governor, both the sparkplug and ignitor models used this type, one with threads and one with a cross pin (the early models had two valves with pins only, no threads), the lathe is a Grizzly Industrial model G9972Z, 11″ X 26″, bench type with gear box, (((one problem with this lathe as shipped is the low end speed range (150 RPM) needed for machining cast iron))), other than that it’s not a bad machine for a homeshop and I have had no problems with this lathe and the price was right,,,,, comments, leave ‘em if you got ‘em,, subscribe, pass it on, this is #1 of this how to build intake and exhaust valves series, to be continued,,,
