Abstract
1422566 Valves BRUNSWICK CORP 22 March 1973 [7 Aug 1972] 13970/73 Heading F2V A rotary plug valve comprises a main valve housing 12 having a circular valve seat 18, a rotary plug 14 being "C"-shaped with two ears 28, 28<SP>1</SP> and a face, journally mounted on removable trunnions 27 and having a circular sealing surface 16 on the face of the plug to effect a seal with a circular sealing surface on the valve seat, and a circular access port 22 having a diameter that is smaller than the exterior ear to ear distance of the plug but large enough to permit insertion or removal of the plug by manipulation when the trunnions 27 are removed and the valve is rotated to the open position, the port having a cross-sectional area 1À0 to 1À6 times greater than a main flow cavity 20 encircling the valve seat 18. The sealing surfaces of the plug or valve seat may be separately removable seals or both may be integral providing metal-to-metal contact.
