The area where a valve closes in the combustion chamber of a four-stroke engine is called the valve seat. During a valve job, this seat is ground at a set angle, usually 45 degrees, for a good seal. In a three-angle valve job, additional angles are ground into each side of the seat angle to ease the transition and improve flow.
The ports of the angle valve ( Inlet and outlet) are oriented at an angle 90 deg.
where the process require the fluide to be leave at right angleto the direction in which it enters at that time we use angle valve
By shutting off the water supply prior to this valve of course
No, you do not have to remove the engine to do a valve job.
To regulate the flow of a liquid or gas.
the interoir angle the exterior angle and the full angle
Three quarters of a right angle is 67.5 degrees.
Triangle - Tri means Three and Angle is an angle
Bicuspid valve.. a birth defect of the aortic valve.
Rather than grinding in the combustion chamber, which would lower the compression ratio, I would think there would be more to gain by working in the valve pocket. Especially the short-side radius and the bottom of the valve guide. Also, a good three-angle valve job can improve flow through the head.
