6” High Velocity PV Valve

Category: Venting Products
  • QUIET AUTOMATIC OPERATION
    The PV-6 II valve has all of the proven design characteristics that have made the original PV-6 valve so reliable. In addition to quiet automatic operation, the vacuum side of the PV-6 II valve has 30% fewer parts, increased flow rate and a 16° angled housing to allow positive drainage of any cargo condensation.
  • SIMPLE WEIGHT OPERATED DESIGN
    Our weight operated design doesn’t suffer from the performance variations caused by spring deterioration or the increased friction between internal guide stems and bushings common with friction-type designs. All operating mechanisms are located outside of the vapor stream eliminates the possibility of valve sticking due to product or contaminant build-up. Also the vacuum side of the valve is angled for positive drainage of cargo condensation back into the vapor header.

  • SET POINT REPEATABILITY 3%
    Unique low friction design utilizes sealed stainless steel roller bearings outside of the vapor exhaust stream allowing the valve to open repeatedly within 3% of factory stated set opening point. Two easily reached test handles, as required by law, allow for easy testing.

  • 100% STAINLESS STEEL
    The main valve body is made of 1/2” thick stainless steel, with 1/4” pipe. Even the bearings and the full weather covers are stainless steel.

  • HIGH VELOCITY DISCHARGE
    The minimum discharge velocity rate of 40 meters/second is achieved at even the lowest flow rates. The unique pressure focusing nozzle creates a columnar exhaust flow path allowing vapors to disburse well above the deck level.
