Series 4960 / 4970 / 4980 / 5960 Gauge Hatch
Brand: Protectoseal CompanyThe Protectoseal Gauge Hatches provide ready access to storage tank’s interior for inspection, gauging and sampling.
Gauge Hatches are intended for use where the fire protection afforded by a Protectoseal flame arrester is not considered necessary.
The lockdown feature on the Series 4970 / 5960 makes them particularly suited for use on tanks with normal operating pressure under 3 psiG.
Tightening the thumb screw holds the cover securely in place, thereby minimizing leakage and evaporation losses.
The Series 4960 / 4980 Gauge Hatches with Free-Lifting Covers have nominal opening pressures (based on their weight), but they should not be considered as primary pressure relief devices.
Vapors relieved are expelled to atmosphere.
