Synthetic Rubber3146 Series, 3176 Series, A3186, A3196 General InformationRegO Back Pressure Check Valves are designed to allow flow in one direction only. The check, normally held in the closed position by a spring, precludes the possibility of flow out of the Container . When flow starts into the Container , the Pressure overcomes the force of the spring to open the check. When the flow stops or reverses, the check seats will allow slight leakage after closure. These Valves will restrict the escape of Container contents in the event of accidental breakage of the piping or Pressure Valves for Container or Line Applications 3146 Series, 3176 Series, A3186, A3187S, A3196, and A3276 BCA3276 BCA3187SA3198 SContainer ServiceTypical InstallationInstallation3146, A3146, 3146S, 3147S, A3276BC, 3176, A3176, A3186, A319610 REGO PRODUCTS 10 YEAR WARRANTYF30F100 RegO Dr.

May also be used in the line applications where flow must be limited to one used with the appropriate single check filler valve, the combination forms a double check filler valve suitable for use in filling of bulk storage swing-away check offers more efficient flow rates than conventional designs. It swivels open vertically to reduce Pressure drop across the valve and improves flow Swing-away check design offers faster flow rates.
