Blackmer Expands BV2 Bypass Valves To Include High-Grade FKM O-rings

The presence of FKM O-rings allows the BV2 valves to be used in a wider range of truck and process applications, including use with biofuels and many process applications that may not have been compatible with Buna O-rings. One thing to note should you choose to use FKM O-rings: they are not UL-listed and cannot be used in applications that require UL-listed equipment, such as in LPG or anhydrous ammonia applications.

Earlier this year, Blackmer upgraded its BV2 Bypass Valve line so that it is now available with optional flange sizes and styles. In addition to the traditional 2-inch NPT and 2-inch Weld flanges, the BV2 is available with optional 1.25-inch NPT or Weld, 1.5-inch NPT or Weld and 2-inch Weld Elbow bolt-on flanges. The option of using these flanges increases the versatility and ease of installation of the BV2 Bypass Valve line.

Blackmer bypass valves have been specifically designed to provide an external bypass control to protect pumps and system components from excessive pressure damage. Blackmer valves provide exceptionally 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.
