Slow Close Check Valves Diaphragm Actuated

The VAG/GA Industries Figure 5273 Slow Close Check Valve will fully open when inlet pressure is greater than outlet pressure allowing flow. The check valve will close drip tight via the control connected from the outlet to the cover when outlet pressure is greater than the inlet pressure. Opening and closing speed control valves are included with the check valve to prevent surges in the line when the check valve opens and closes. In addition, the Figure 5273 is standard with epoxy coating internally and externally for corrosion protection, as well as isolation valves for quick and easy maintenance or repair.  See the Slow Close Check Valve Data Sheet for additional information.
