Detailed Description for Double Beat Valves

The shape of the double beat valve is of hollow cylinder with two seats of approximate diameter, at A and B in the figure. The cylinder is attached to the actuating rod by a web. The energy needed to lift the valve is determined on the basis of variance between diameters D and d: the smaller this difference can be made, the less the power necessary to open the valve. The steam drifts past seat B only. In later progression of the valve, the central portion is waisted so that the flow can pass at A as well, so expanding the valve opening area for the same amount of lift.

 Double Beat Valves is a kind of poppet valve arranged to permit it to be unfastened against a high pressure with a slightest force. One of its applications is in steam engines to all steam to move into the cylinders and to discharge the exhaust.
