Injection valves

Griffco injection valves are designed to ensure that the chemical dose of the fluid is injected into the centre of a process stream. This not only ensures better mixing of the dose in the fluid, but also prevents corrosion of the process pipe wall.
The check valve prevents the process fluid from going back up the feed line. The robust construction ensures reliability during maintenance or servicing.
