Pressure and Vacuum Relief Valves, in-line

These devices are direct acting weight or spring loaded in-line valves, pallet type, used to protect plant equipment (tanks, vessels, process technical apparatus, piping etc.) against unallowable operational high pressure or vacuum. In-line valves may also be installed as end-of-line valves. In end-of-line applications the open area to atmosphere has to be protected against weather impact, dirt particles or animals.
