Stainless Steel is recommended for high temperature applications 130F causing it to oat; the valve is 3. Larger outlet sizes are available OPENED, allowing oil-free water to discharge. As oil starts to OSV Options accumulate around the sphere,Slave Valve for dry vault applications the sphere will sink lower.
