A waste container crusher particularly adapted for crushing automotive type oil filters or other structurally rigid disposables containing hazardous waste has a housing with an open bottom which is closed off by an anvil plate. The anvil plate slideably receives three equiangularly spaced posts which are secured to a roof plate at the top of the housing, above the anvil plate. Nuts on the posts support the anvil plate below the roof plate, so that the anvil plate is suspended from the roof plate by the posts. The roof plate is secured to a hydraulic cylinder which produces a 10 ton driving force for a platen guided by the posts to crush a container placed on the anvil plate below the platen. In the anvil plate, four blind bores in a rectangular pattern in the top surface intersect a central blind bore extending from the bottom surface, and a smaller central through-bore provides communication between the lower central blind bore and the top of the anvil plate. In one embodiment, a pneumatic-hydraulic control circuit is provided in which the hydraulic cylinder is driven until an air powered hydraulic pump stalls. In an alternate embodiment, an electro-hydraulic control circuit drives the hydraulic cylinder according to a timed cycle.

A modular valve has a valve housing which defines a manifold interface having a normally open port, a normally closed port and a common port. A manifold block is mounted to the valve housing with its valve interface sealed against the manifold interface. The valve interface of the manifold block has first, second and third valve ports which lead to respective first, second and third mounting ports at a mounting interface of the manifold block. The first, second and third valve ports and the normally open normally closed and common ports are arranged to communicate with one another in either of two angularly spaced positions of the valve housing relative to the manifold block. In one position, the first valve port comunicates with the normally open port, the second valve port communicates with the normally closed port, and the third valve port communicates with the common port. In the other position, the first valve port communicates with the normally closed port, the second valve port communicates with the normally open port, and the third valve port communicates with the common port.
