Heavy-Duty Corporation Stops Datasheet
Heavy-duty, with lead-free brass or 316 SS valves
Process connection MNPT: 1/2″, 3/4″, 1″
Every heavy-duty corporation stop comes with two injection safety chains. The first prevents the injection quill from being completely withdrawn before the corporation stop is closed, a safety feature to protect against back pressure; the second secures the quill while it is in operation.
