The Rego 8017DP is designed especially for use as a high capacity liquid withdrawal valve on LP-Gas/anhydrous ammonia containers. These valves incorporate an integral excess flow valve. When product is required, the valve must be completely open and backseated to allow the excess flow valve to function properly as explained in the excess flow valve section of this catalog. No internal relief.
•Positive-acting excess flow valve opens for maximum flow at minimum pressure drop when filling — regardless of the type of coupling in which the valve is installed.
•Excess flow seat is fully contained in the tank coupling for maximum protection in the event of external damage to the valve.
•Resilient seat disc assembly is fully contained on three sides for bubble-tight shut-off and long service life.
• “V”-ring spring loaded stem seal design requires no repacking or field adjustment.
