Pressure Relief & Vacuum Valves

Pressure Relief Valves

Pressure Relief Valves (PRVs) are valves used to control or limit pressure in a system or vessel which can build up for a process upset, instrument or equipment failure, or fire.

More Info

Vacuum Relief Valves

Equipment must be protected against being subjected to an internal vacuum (i.e., low pressure) that is lower than the equipment can withstand.

More Info

Rupture Discs

A rupture disc (or bursting disc) functions as a pre-designed "weak point" in a pressurized system. Rupture discs should be the strongest part of your pressure protection system.

More Info

Test Insert / Pipe Covers

Test insert assemblies are placed between relief valves and shut-off valves (block valves) so relief valves can be isolated and tested in place through the port of the test insert.
