DOUBLE BLOCK AND VENT VALVE ABSTRACT A valve has an upper region connectable to a first piping system, a lower region connectable to a second piping system and an intermediate passageway therebetween which is opened and closed by a valve member which is reciprocated by an overhead actuator. The valve member has first and second members which are slidable relative to one another. In the closed position, the first and second valve members seal with spaced apart seats and define therebetween an intermediate chamber including the surface of the interior passageway between the seals. A lower valve member extending exterior of the lower region has cleaning solution inlet and outlet passageways which communicate with the intermediate chamber whereby the surfaces of the intermediate chamber may be cleaned and whereby any leakage around either of the seals is drained externally. In the open position in which the valve member is positioned in the upper region, the first and second parts are biased together and a seal is formed between the valve member parts to block communication between the piping systems, the cleaning solution passageways of the valve member and drain.
