The Fetterolf “Poppet”- type Ram-Seal valve utilizes a disc which rises into the vessel or reactor on opening to break through any material which might crust or bridge.

                The rising disc utilizes the same Ram-Seal system which has proven itself as a drop-tight, zero leakage design which may be used for full vacuum systems or pressurized systems up to 5000PSI.

                On closing, the resilient seal-ring on the disc(plunger head) receives a reactive force from the compression ring contacting a land inside the valve body. This compressive force expands the seal ring in all directions, forming a wide-band seal against the body wall and the disc. Metal-to-Metal seating is available as is a removable-replaceable seat design.

                On opening, the plunger rises into the vessel, allowing the fluid to drain around the valve disc rod.

                Design and manufacturing flexibility of Fetterolf allows dimensions to vary and match those of existing or obsolete Poppet – type values in every detail.
