Abstract
An irrigation valve comprises a housing including a chamber, a fluid inlet comprising a fluid inlet passage configured to fluidly communicate with a first conduit, wherein the fluid inlet is configured to communicate fluid from the first conduit to the chamber, a fluid outlet comprising a fluid outlet passage configured to fluidly communicate with a second conduit, wherein the fluid outlet is configured to communicate fluid from the chamber to the second conduit, a rigid substrate and a stretchable, compressible and/or flexible membrane on a surface of the rigid substrate, wherein the rigid substrate is configured to be positioned so that the membrane is located between the fluid inlet and the fluid outlet when the valve is in a closed position, and wherein a fluid pressure within the chamber causes the membrane to seal a first orifice of the fluid outlet passage when the valve is in the closed position.
