The present invention relates to a chemical sprayer that includes a sprayer head assembly and a container. The container defines a cavity for storing a chemical to be sprayed. The sprayer head assembly includes a chemical passage, a carrier fluid passage, a vent passage, a valve chamber and a valve. The chemical passage is communication with the cavity. The carrier fluid passage is in communication with a carrier fluid source. Both the carrier fluid and chemical passages are in communication with the valve chamber. The valve is moveably positioned within the valve chamber and defines at least partially a first passage and a second passage. The first passage is configured so as to be in communication with the chemical passage when the valve is in an open position. The second passage is configured so as to be in communication with the carrier fluid passage when the valve is in the open position. The first and second passages are also configured so as to not be in communication with the chemical and carrier fluid passages when said valve is in a closed position. The valve also includes one or more seal portions positioned on the valve so as to block both the chemical and the carrier fluid passages when said valve is in the closed position. The sealing portions also preferably blocks a vent passage when the valve in the closed position. The second passage also preferably forms at least in part an outlet of the sprayer head assembly. A suction generating surface is also preferably defined by the valve.
