The Shand & Jurs FRP 94063 Series Manhole Cover is designed to provide emergency venting relief of low-pressure storage tanks and vessels. These covers also provide quick, easy access for tank inspection and maintenance. When the tank is exposed to abnormal internal pressure beyond the capability of the conservation vent, the manhole protects the tank against costly rupture.

The Shand & Jurs FRP 94063 Series Manhole Cover provides an effective vapor-tight seal until pressure relief is required to protect the tank. Under emergency flame conditions, the cover opens fully to allow escape of vapors and prevents damage to the tank.

Construction

Fast Inspection, Easy Maintenance
Unit's rugged and lightweight design provides for easy, convenient handling for installation, inspection and maintenance. The pressure cover is normally restrained to allow automatic reseating. Disconnection of the retaining cord allows the pressure vent cover to be completely removed, thereby allowing access into the tank through the full diameter seat opening. Facilitates tank inspection and repair procedures.

Maintains Accurate Pressure Setting
Factory tested prior to shipment to meet Shand & Jurs high standards. Standard pressure setting of ¾ oz/inē on all models. Higher settings are also available.
