Accu-Vent Automatic Degassing Valves are designed to automatically vent gases and vapors that are commonly released from chemicals such as Sodium Hypochlorite or Hydrogen Peroxide or Sulfuric Acid.
Standard Features include CPVC (Corzan) and Viton corrosion resistant wetted materials of construction,
specially designed float material automatically vents built up gases on system start up and under working pressure, it can be used on feed side or discharge side of pump (or both), standard 1/2"" NPT threaded connections or optional 3/4"" NPT. Available in other materials of construction for various gaseous liquid chemicals.
Gases or vapor are compressible, if not vented cause what is known as vapor lock in your metering pump and the system. This originates malfunction in the metering pump and in most cases failure on discharging chemical to the system.
The valve is designed to allow for the venting of gases and condensed vapor back to the feed tank, which improves priming on initial startups and continuous trouble free operation while working under pressure.
The valve when in operation vents gases, vapor and a small amount of liquid, which is the same as the chemical being pumped. This discharge must be returned through hard piping or tubing back to tank, to prevent personnel or equipment from coming in contact with the vented corrosive liquid.
