It is an air-operated valve with an external air cylinder and a 90-degree elbow outlet, used as a safety shutoff at the bottom of a tanker. The valve incorporates a Teflon (Tef-O-Sil) seat for broad chemical compatibility and a fusible plug for fire safety. It is typically replaced when the valve fails to hold pressure, becomes damaged in an accident, or when the seal material no longer suits the product being transported.
