Maximum Design Flow Rates

The Product recommended maximum design flow rates, permitted at activation, are listed in the Maximum Design Flow Rates Table below – applicable for all stainless steel, carbon steel and high nickel alloy breakaway couplings.

1. OPEN: the two flaps interlock, offering the minimum head-loss until the breakaway coupling separates.

2. BREAKAWAY LOAD EXCEEDED: the breakstuds elongate and the flaps are released and rotate through a controlled arc.

3. CLOSED: the flaps have moved through 90 degrees, where they snap onto their seats prior to the breakaway coupling fully separating.

4. BREAKAWAY: with 100% shut-off achieved, the two halves of the breakaway coupling then separate completely.
