WebThese valves are typically gravity operated and require very little back pressure seal. Air release or vent valve safety allows any entrapped air or gas to escape, avoiding potential damage to the piping system. Ball check valves are ideal for vertical service and some designs can be used horizontally. Web1. Multiply flow rate (gpm) by 3, 157 2. Multiply specific gravity by total of Step 1 3. Multiply viscosity (cp) by pipe ID (inches) 4. Divide total of Step 2 by total of Step 3 For technical drawings and 3-D models, click on a part number.
