Suggestion:

Safety valves are suitable for clean, particle-free, low-viscosity fluids. When a safety valve must be installed in the presence of particles, consideration should be given to installing a filtering device in front of the safety valve. The filtering device must ensure that the performance of the safety valve will not be affected.

Where a safety relief device is required and it is not suitable to install a separate safety valve, a rupture disc or a combination of safety valve and rupture disc may be used.
