Abstract: A valve system automatically controlled by an expanding/contracting material and method of dispersing fluid through valve system are provided. The expanding/contracting material may be a hydrophilic material, wherein providing fluid to the hydrophilic material causes it to expand and constrict a hose or tubes dispersing fluid to a designated area. The constriction of the hose or tubes prevents fluid from coming into contact with the hydrophilic material allowing for the hydrophilic material to dry and contract, thereby releasing the pressure from the hose or tubes.
