VAG GA Industries Figure 931-D is a Figure 930 Air & Vacuum Valve and a “surge check” valve factory assembled and tested as a unit. This valve system vents air during filling and admits air during draining. Pus, the surge check’s “slow closing” adjustable regulated exhaust feature minimizes surges, shock and valve damage caused by sudden air valve closure due to column separation/rejoining. 

Figure 931-DT is standard with NPT outlet, optional cowl. The Figure 931-DC is standard with an outlet cowl while the Figure 931-DJ has a Class 125 flanged outlet.
