Safe Expulsion Of Unwanted Air In Piping Systems

Product Announcement from Plast-O-Matic Valves, Inc.

Safe Expulsion Of Unwanted Air In Piping Systems-Image
  • Safety: Allows safe expulsion of unwanted air in piping systems.
  • Dependability: Patent-pending float mechanism assures minimal emission of system liquid prior to sealing.
  • Minimal Closing Pressure: Closes at 0 PSI, as long as liquid is present.
  • Cost Efficient: Designed to improve system performance and competitively priced.
  • Superior Design: Valve opens and closes automatically, over and over and over.
  • Corrosion Resistant: Top quality thermoplastics and elastomers resist chemical attack and protect system purity. No metal components in Series DGV.

Series DGV Thermoplastic Degassing Valves...

Continuously Expels Trace Amounts of Gas as it Occurs


• Reduces replacement costs - no internal or external metal components; ideal for aggressive environments.
• Placed at the high point of a piping system, this innovative valve will vent gas as it occurs. A unique float/actuating lever allows the vent orifice to open when gas is present. After gas vents, liquid forces the vent to close. Whenever gas accumulates, the valve will re-open until the gas is vented.
• All-plastic construction designed for sodium hypochlorite, ozone systems, or any liquids prone to outgassing.
• Series DGV is designed for systems that continuously generate trace amounts of gasses. For system start-up requiring rapid expulsion of larger volume of air or gasses, see Series ARV.
