Principle of Operation

The 2100 Series maintains a tight seal until system

pressure exceeds the set pressure of the vent. To adjust

the set pressure, a series of weights may be stacked

onto the lid assembly. When excessive overpressure

occurs the weighted lid assembly lifts, breaking the seal

between the seat and seal portion of the lid assembly.

This allows vapors to pass through the vent orifice and

relieve pressure buildup. The vent reseals upon relief

and remains sealed; tethered lids may blow completely

off in a catastrophic pressure event (see Figure 4).

It is important to know that relieving vapors near the

set pressure in a continuous manner may cause the

lid assembly to flutter or oscillate. This is a common

occurrence in products of this type in the industry.

Operating the vent with flutter or oscillation over time

may cause premature vent damage or wear. Please

feel free to contact your local Sales Office with any

questions or for information on proper tank venting.
