A valve body for an irrigation system is disclosed. The valve body is formed as a unitary molding and comprises a manifold arrangement integrally formed in the valve body and includes an inlet and at least one outlet. The manifold arrangement includes a valve receiving region located between the inlet and each outlet where each valve receiving region is operable to receive a valve to selectively control the flow of liquid between the inlet and each respective outlet of the manifold arrangement.

Irrigation apparatus

A watering device includes a main body having a main inlet for receiving pressurized water and an intermediate cap member in fluid communication and sealingly engaged with the main body. The watering device also includes a top cap member sealingly engaged with the intermediate cap member. The top cap member includes at least one watering outlet. The watering device also includes a diaphragm substantially covering a base portion of the intermediate cap member and arranged to interact with water flowing from the main body to divert water to function as a pressure compensator for substantially maintaining the flow rate of the watering device.

Watering device

The invention provides an improved miniature spray device () for providing uniform water distribution over a designated area surrounding the device (). The spray device () comprises a spray plate () which is provided with a water dispersion surface () which is preferably cone shaped, a water outlet () for directing a stream of water from a pressurized source towards a central region of the spray plate (), a support frame () for holding the spray plate () in spaced apart relation to and in alignment with the water outlet (), wherein the water dispersion surface () is provided with flow deflection means () for changing the direction of flow of the water as it flows over the surface () to produce a substantially uniformly distributed spray pattern.
