Notes		When selecting either Flare Grip® or Grab Seal™ ends, we recommend end connections that are larger than the valve orifice size in order to achieve full flow. Adjusting to near zero suckback amount can cause the valve not to seal fully and leak across the valve seat. The valve works best if the nozzle is placed no more than four feet (1.2 m) from the valve. Leak detection port on side has standard port size of 1/4 - 28. For applications in concentrated Hydrochloric (HCI) applications, please consult the factory.
