Abstract

A valve fitted in a pipeline has two circular seatings against which external surfaces of valve discs (14, 15) come to rest. Control of the valve is provided by control rod (16) of which the upper part is threaded, the rod being raised or lowered by an internally threaded hand wheel. Pairs of pivot arms (40, 42) secure the valve discs to a sleeve (30) on the lower end of the control rod. When the sleeve is lowered it contacts the bottom of the valve after the lower edges of the discs, the further sleeve movement pivoting the arms (40, 42) which move the discs against the seats. The transmission to the valve discs is via spring bellows (60) urging the discs against seats.
