Double Check Filler Valves for Delivery Truck Tanks and Large Storage Containers 7579S, 6587EC and 3197C

Designed to provide fast filling of bobtails, transports and large bulk storage tanks.

The 6587EC incorporates a swing-away lower check which greatly reduces pressure drop across the valve. This lower pressure drop promotes faster filling rates and greater efficiency resulting in more profitable operations.


    • Double back check provides added system protection.
    • Upper filler valve assembly can be easily replaced without evacuating the container.
    • Both checks are spring actuated for quick, precise closure when flow into the valve stops or reverses.
    • 6587EC swing-away check promotes up to 65% faster filling rates for more profitable operations. Faster filling rates add longer pump life by reducing chances of cavitation.
    • Specify RegO® Filler Valves on all your original tank purchases to insure quality and dependable performance.
