Larox Offers Air Release/Vacuum Valve

The air/vacuum valve from Larox Flowsys Inc. automatically exhausts large volumes of air from the system while it is being filled with slurry. Air displaces the fluid and re-enters the pipeline to equalize pressure when the contamination is being emptied, preventing discharge of the medium. When the system is filled and operating, fluid lifts the ball until it closes the orifice, which remains 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 system pressure drops to near atmospheric and the ball is no longer buoyant. Sizes range from 2 to 8 inches in diameter with pressures of 240, 365, 600 and 1,500 psig. 410/636-2250; www.larox.us.
