A new Air/Vacuum Valve from Larox automatically exhausts large volumes of air from a pipeline. When the system is filled and operating, the fluid lifts the ball until it closes the orifice. The orifice will remain closed until the system is emptied. Air may enter the valve and displace the fluid while the system is operating, but the internal pressure will keep the valve tightly shut. The valve will not re-open until the system pressure drops to near atmospheric pressure and the ball is no longer buoyant.

Water meters
Neptune Technology Group has announced that all its bronze meters currently meet the future lead-free requirements of the Safe Drinking Water Act as well as planned revisions to NSF/ANSI standards regarding lead in drinking water system components. In 2001, the company made a significant investment to switch to lead-free bronze. With this investment, Neptune became the first North American water meter manufacturer with facilities dedicated to lead-free operations, production, and testing.

PVC pipe restraint
With the advent of increased pressure ratings being given for 4” – 12” sized C900 and C909 PVC pipe (as noted in the latest revisions of the applicable American Water Works Association industry standards and as adopted by the Uni-Bell PVC Pipe Association), EBAA Iron engineers have recently developed an appropriately designed split serrated restraint ring device that will provide the necessary restraint capabilities now required to accommodate these higher working pressures that have been assigned to PVC pipe. The EBAA 1900 series split serrated restraint ring product can restrain C900 & C909 PVC pipe for water and wastewater applications – whether above or below ground, and in residential or industrial piping applications.
