DESCRIPTION
The Protectoseal Gauge Hatches provide ready access to the storage tank’s interior for inspection, gauging and sampling. Gauge hatches are intended for use where the fire protection afforded by the 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 minimising leakage and evaporation losses. The Series 4960 / 4980 Gauge Hatches with Free-Lifting Covers have nominal opening pressures (based on weight), but they should not be considered primary pressure relief devices. Vapours relieved are expelled into the atmosphere.
