Abstract
An irrigation valve has a valve body with an inlet passage, an outlet passage, and a valve seat intermediate the inlet passage and the outlet passage. A diaphragm includes a valve seat engaging portion that cooperates with the valve seat to control flow through the valve. The valve seat and the valve seat engaging portion of the diaphragm are offset relative to the inlet passage to improve flow through the valve to reduce pressure and energy loss.
