Abstract

1502949 Valves ASSOCIATED ELECTRICAL INDUSTRIES Ltd 30 June 1975 [15 July 1974] 31264/74 Heading F2V A control valve has a body 18 with inlet and outlet ports 19, 20; a seat 21 and a co-operating valve head 25 each with radial sealing surfaces, the head being movable between closed and open positions by at least one half of a revolution of a control means 27, flow through the valve being stopped by abutment of the head against the seat and being caused to increase smoothly during transition to the open position by the smooth increase in the space between the seat bore 22 and a throttling portion 24 of the valve head. The throttling portion may be domed or in the form of a truncated cone and may have a shallow cylindrical base, Figs. 3, 4 (not shown). The seat bore may be tapered and the seat may be separable from the body. The sealing portion of the head may be an annular washer.
