633LVH - 4" Vapor Recovery Adaptor
633LVH Vapor Recovery Adaptor

Civacon's 633LVH high-flow, low pressure drop poppeted vapor recovery fitting permits simultaneous multiple compartment loading at +1000GPM without exceeding the pressure rating of the PV vents. The same high-flow design delivers faster unloading, too.

  • High flow rate/low pressure drop design affords faster loading
  • Two sight glasses, along with a 3/4" pipe plug, facilitate easy detection and draining of liquids in case of accidental overfill
  • Proper vapor collection -- with superior flow characteristics -- means vents are less likely to pop open from compartment back-pressure. As a result, there's less chance of vapor loss to the atmosphere
  • Includes Model 101 Air Interlock Valve
  • Drilled mounting pad for optional air interlock valve
