Emerson Fisher's C484-24 Series 3 in. Internal Valve is a single flange unit widely used on bobtail and transport trucks for compact means of direct pump connection to the valve outlet. Also used on in-line installations.
Flanged valves provide a sturdy and compact means of directly mounting a pump or piping connection. Special stud bolts, weakened with a groove on the outside diameter, are furnished with the valves to permit the pump or piping to shear off in the event of an accident, leaving the valve intact. A build-in excess flow valve reduces the chance of uncontrolled product discharge when flow exceeds the rated flow capacity.
