  • AUTOMATIC OPERATION

    The Equate PV-4, 4" P-V Valve is designed to automatically maintain safe design working pressure and vacuum levels within your barge. Your barge remains closed vapor tight until set point pressure or vacuum overcomes the force of each respective set point spring, allowing vapor flow out or air flow in, at a rate sufficient to maintain safe levels within your barge.

  • SIMPLE DESIGN

    Having very few parts, the Equate P-V valve is spring operated with one spring to determine the pressure set opening point and the second spring to determine the vacuum set opening point. A manual test handle allows the tankerman to check operation of both the pressure and vacuum sides of the valve. Both the test handle and valve weather covers are easily removed allowing complete valve inspection in minutes. Easy to replace elastomer seals, one pressure and one vacuum seal, insure vapor tightness.

  • 100% STAINLESS STEEL

    All components are 300 series stainless steel for extended service life and reduce need for maintenance. The resilient pressure and vacuum seals are the only parts that are not stainless steel.

  • CERTIFIED TO MEET ALL USCG REQUIREMENTS

    Every Equate P-V Valve is 100% factory tested prior to shipment and is USCG Approved.
