Product Introduction

A tall rectangular panel gives this equipment door a different mounting footprint from the compact square hatch. The assembly combines 316 stainless construction, a bolted frame and a silicone sealing interface. Its hinged panel is intended to return after relief rather than operate as a disposable rupture sheet. The panel dimensions describe the closure, not the full external flange. The surrounding vessel must accommodate the frame and moving panel, with the vent path directed away from occupied work areas.
