Bypass valves available with flange styles, sizes

February 24, 2009 By    

Blackmer’s line of BV2 bypass valves is now available with optional flange styles and sizes. BV2 bypass valves have always been offered with optional 2-inch NPT or 2-inch weld flanges, but they are now available with optional 1.25-inch NPT or weld, 1.5-inch NPT or weld and 2-inch weld elbow bolt-on flanges. According to the company, the incorporation of these additional flange styles will increase the versatility and ease the installation of the BV2 bypass valves. Bypass valves are specifically designed to provide an external bypass control to protect pumps and system components from excessive pressure damage. Blackmer says its valves provide reliable close pressure control even under widely varying bypass flow conditions. Each valve is designed to open precisely at a preset spring pressure and close smoothly and quietly. The introduction of the new bolt-on flange sizes will give the customers a wider range of configurations to choose from, making Blackmer’s BV2 bypass valves applicable for more installations.
