723V Pressure Vacuum Vent

Pressure Vacuum Vents are installed on the top of vent pipes from underground or above ground fuel storage tanks. The vent cap and internal wire screen are designed to protect the tank vent lines against intrusion and blockage from water, debris or insects. A normally closed poppet in the valve opens at a predetermined pressure or vacuum setting to allow the tank to vent.

Features

Preset and Tested Factory Settings – 2.5" to 6" water column pressure settings and -6" to -10" water column vacuum settings.
Cycle Tested for Reliability – tested to the equivalent of 80 years of service in the most severe environment without leakage problems.
Long Service Life – corrosion-resistant Duratuff® composite construction.
Easy Installation – the 723V is available in 2" and 3" threaded versions.
Complies with NFPA 30 Requirements – for venting gasoline vapors upward.
Manifold Vent Pipes – vent pipes may be manifolded to produce a single Pressure Vacuum Vent line. The 723V exceeds California’s requirements of a maximum vapor leak rate of 0.17 SCFH at 2.00 inches H2O.
High Maximum Flow Rate – 6450 SCFH at 2 psi (0.1 bar) pressure drop.
Leak Rate – multiple pressure vacuum vents may be installed on a single site. The 723V exceeds California standards with a leak rate of 0.05 SCFH or less at 2.00 inches H2O.
No Tools Required – a removable snap fit top allows for easy maintenance (recommended yearly).
Screened Tank Vent Lines – a 65 micron stainless steel screen helps prevent debris and insects from entering the tank vent lines. An added screen installed at the base prevents debris from intruding from the vent stack.
Removable Threaded Bushing – designed for easy installation on NPT threaded risers. Allows easy access to lower screen.
