Abstract of the Disclosure A diaphragm-type check valve for vacuum pipes is provided which enables opening of the valve using substantially less operating force than is required in conventional valves of the same size and type. The valve includes a flexible diaphragm which is disposed in the pipe and is held in its closed position by the vacuum in the pipe. A mechanical operator such as a vacuum- actuated piston causes opening of the valve. A cavity located on the side of the diaphram opposite that which is exposed to the pipe vacuum is selectively connected to a source of suction or vacuum (preferably that provided by the pipe itself) so as to substantially equalize the pressure on both sides of the diaphragm and thereby enable opening of the valve with a less bulky operating mechanism that provides only the reduced operating force referred to above.
