Excess Flow, Check, Filler & Vapor Equalizing Valves

RegO ® Excess Flow, Check, Filler, & Vapor Equalizing ValvesSwing-Away Back Pressure Check Valves forContainer or Line ApplicationsUL®Designed to provide protection of a container opening when desired flowis always into the vessel. May also be used in the line applications whereflow must be limited to one direction.When used with the appropriate single check filler valve, the combinationforms a double check filler valve suitable for use in filling of bulk storagetanks.The swing-away check offers more efficient flow rates than conventionaldesigns. It swivels open vertically to reduce pressure drop across thevalve and improves flow rates.Part Number Inlet Connection Outlet Connection Wrench Effective Length Propane Liquid Capacity at Various Differential Pressures (GPM)Brass Steel F.

The unobstructed throat area reduces flowturbulence through the valve, thereby reducing pressure drop. Large flowchannels and spacious side ports assure ample capacity for the mostdemanding high capacity filling operations.The valve is designed for installation in internally threaded flanges in containerbottoms.Part NumberFlange ConnectionM.

With glass on both sides of the indicator, flowcan be observed from either side, even under some poor light conditions. The integral swingcheck also serves as a back-check valve to prevent reverse flow and product loss if the hosefails in a loading operation.By installing an indicator on the upstream side of the plant pump, suction conditions can beobserved and the pump speed adjusted to obtain the maximum possible flow rate withoutcavitation. Additionally, if an indicator is installed in the piping at the loading rack, just aheadof the loading hose, the operator can maintain a constant check on pump conditions.Both installations are designed to allow for observation to provide maximum pump efficiencyand assure safe plant pump operation.In compressor operations a sight flow indicator installed in the liquid line will give a visualindication when the tank car or transport is emptied. Compressor operation can then beimmediately reversed to start recovery of the vapor.PartNumberInlet/OutletConnectionsLengthA7794 2" F. NPT 5 3 ⁄4"A7796 3" F.
