Guidance on the proper placement of safety valves to prevent malfunction.

The configuration of the piping between the protected vessel and the safety device is highly critical. The document mandates that inlet piping must be as short and direct as possible. Excessive pressure drop across the inlet piping causes "chattering"—a rapid, destructive opening and closing cycle of the valve. The standard demands that the pressure loss in the inlet line must not exceed a strict percentage of the valve's set pressure under maximum flow conditions. 2.
