The 2" Diaphragm Support is for the PGV-201. Built with enough durability to handle the rigors of most residential and light commercial sites, the PGV is available in an array of configurations. For smaller landscape applications, the PGV is available in four 1" body configurations: angle, globe, male x male, or male x barb design. In turn, each model is available in either a flow control or non-flow control version.
