Handling
Always keep the inlet flange down on a crated or uncrated flange valve to prevent
misalignment and damage to valve internals.
Pilot Operated Safety Relief Valves should be handled carefully. The internal parts of a pilot
operated safety relief valve are precision machined and fitted together to maintain perfect
alignment. Rough handling may damage the external tubing, pilot, and main valve seats or
may cause misalignment sufficient to incur leakage or erratic operation. POSRVs are shipped
with a protective covering over the inlet and the outlet flanges. This is to prevent damage to
the flanged surfaces and to prevent entry of foreign material into the valve.
Never lift the full weight of the valve by the pilot assembly, external devices or
tubing.
Do not rotate the valve horizontally or lift/carry using the pilot assembly.
Only lift the valve by the eyebolts inserted into the cover plate.
Handle carefully. Do not drop or strike the valve.
Storage
Store POSRVs in a dry environment and protect them from the weather. Do not remove the
valve from the skids or crates until immediately before installation. Do not remove flange
protectors and seating plugs until the valve is ready to be bolted into place during the
installation, i.e., both inlet and outlet.
