Bellows Seal Valve
Conval’s Clampseal® Bellows Seal valves provide a zero-emission solution, perfect for situations where traditional packed valves might struggle to contain light gases or hazardous fluids due to potential leakage in the stem/packing seal or stuffing box wall/packing seal zones. The valves can be installed in the pressure boundary zone of nuclear plants to ensure reliable and tight shutoff, emitting zero emissions.
These valves not only ensure environmental compliance but also adhere to all specifications outlined in MSS SP-117. Conval Bellows Seal valves are also designed with a pressure seal bonnet that provides easy access for servicing with no welds to cut or seal rings or gaskets to replace.
