H-Tec Air Release and Vacuum Valves for Wastewater

  • Innovative Design
    The large body prevents contamination by creating a large air gap. The beveled bottom allows debris to be quickly and easily flushed back into the force main. The smooth interior surface ensures debris does not plug the valve. The debris shield prevents solids from contaminating the seal.
  • Non-Leaking
    The valve will seal drip tight even at 0 psi pressure in the process piping. Traditional ARV’s require 3 PSI or more to seal resulting in a release of sewage.
  • Infinitely Variable Air Discharge/Intake
    The unique cup seal allows infinitely variable amounts of air in, or out as needed by the application.
  • Easy Maintenance
    The working parts of the valve can be removed easily through the top of the valve, and the cup seal is simple and easy to replace. H-Tec air valves are easy to assemble and disassemble.
  • Corrosion Resistant Materials
    The internal components are stainless steel and high grade plastics such as Buna-N, Polyethylene, and Delrin®. They will not corrode in wastewater applications. The body can be epoxy coated steel, or stainless steel. H-Tec valves are designed to provide years of dependable service in corrosive environments.
  • Light Weight
    H-Tec valves weigh much less than traditional air release valves making installation and maintenance easier.
  • Readily Available Parts and Service
    Parts and service are readily available and easy to obtain.
