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.

Marc Soucy, P.Eng

National Sales Manager

I am a mechanical engineer with 30 years of plant, sales and service experience. I have been on both sides of the desk and can relate with you when issues arise in the plant. You can trust that I won’t recommend a product unless I know that it will do the job for you.

Marc Soucy, P.Eng

Directeur National des Ventes

J’ai un diplôme en génie mécanique avec 30 ans d’expérience dans les usines, les ventes, et le service. J’ai été de chaque côté du bureau et je comprends lorsque des problèmes font surface dans l’usine, l’importance que l’on doit y apporter. Vous pouvez être sûr que je ne recommanderai pas un produit à moins que je sache qu’il convient à votre application.
