Abstract: A fluid circulation valve assembly comprises a valve body and first and second pressure relief valves. The valve body comprises two inlets to receive output of fluid pumps, two outlets to direct fluid from the two inlets out of the valve body, respectively, and two overpressure outlets to direct fluid from the twos out of the valve body, respectively. The first and second pressure relief valves intersect the two inlets, the two outlets and the two overpressure outlets, respectively. Each pressure relief valve comprises a spring operated overpressure valve configured to open an inlet to an overpressure outlet at an overpressure condition; and a manually operated valve having a first position configured to fluidly connect an inlet to an outlet while not affecting operation of the overpressure valve, and a second position configured to fluidly connect an inlet to an overpressure outlet while opening the overpressure valve.

Abstract: An apparatus for dyeing textile materials is provided that includes one or more chambers for dyeing and one or more storage baskets. The apparatus has a first station with a container hydraulically connected with the chamber. The first station is for the drawing and metering of dyeing solutions and for the admission of the dyeing solutions into the container to feed the chamber for dyeing the material disposed inside the storage basket. A second station has a stirrer. The basket is connected in a stable but removable way to the stirrer. The basket is located in correspondence with the chamber.
