Griffco CS Corporation Stop

Griffco corporation stops operate like injection valves to inject chemical into the centre of the process stream; the difference is that they are retractable and feature a shut-off (ball) valve and radial seal, so the injector quill can be removed for servicing without turning off the process flow.

An integral check valve prevents process fluid from going back up the chemical line. A locking mechanism stops the quill sliding out under system pressure and a locking chain prevents it sliding all the way out during servicing. With limited seals and joints they provide virtually leak-free performance.
