Request Information
Packed valves require two different seals: a 360º seal on the stem and a 360º seal on the stuffing box. The Conval Bellows Seal Valve removes these two leak paths.

Conval Bellows Seal Valves are used when packed valves may not reliably contain light gases or hazardous system fluids. The multi-ply Inconel™ static bellows stem seal is more reliable in most applications than sliding stem seals.

Conval Bellows Seal Valves have two back-up stem seals, a graphite packing and a pressure actuated backseat to contain system fluids in the unlikely event of a Bellows rupture.

Meets all the requirements of MSS-SP117.
