Types C471, C477 and C486 Internal Valves

Failure to follow these instructions or to

properly install and maintain this equipment

could result in an explosion and/or re

causing property damage and personal injury

or death.

Fisher

equipment must be installed, operated

and maintained in accordance with federal,

state and local codes and Emerson Process

Management Regulator Technologies, Inc.

(Emerson™) instructions. The installation

in most states must also comply with NFPA

No. 58 and ANSI Standard K61.1.

Only personnel trained in the proper

procedures, codes, standards and regulations

of the LP-Gas industry should install and

service this equipment.

The internal valve must be closed except

during product transfer. A line break

downstream of a pump may not actuate the

excess ow valve. If any break occurs in the

system or if the excess ow valve closes, the

system should be shut down immediately.

Introduction

Scope of the Manual

This manual covers instructions for the Types C471, C477

and C486 internal valves.

Description

The valves are typically used on the inlets and outlets of

bobtail and transport trucks and on large stationary storage

tanks. They can also be installed in-line. Designed for

propane, butane or NH

at ambient temperatures, the valves

can be used on other compressed gases, but the user should

check with the factory to make sure the valves are suitable for

the particular service.

Specications

The Specications section on the following page shows

specications for Types C471, C477 and C486 internal valves.

DOT Internal Self-Closing Stop Valve Requirement—

U.S. Department of Transportation (DOT) regulations

49CFR§178.337-8(a)(4) require each liquid or vapor

discharge outlet on cargo tanks (except for cargo tanks used

to transport chlorine, carbon dioxide, refrigerated liquid and

certain cargo tanks certied prior to January 1, 1995) to be

tted with an internal self-closing stop valve. Fisher “C” Series

internal valves comply with the internal self-closing stop valve

requirement under the DOT regulations.

Types C471, C477 and C486 valves. It may also be possible to use cable controls from other manufacturers or to fabricate a linkage mechanism. Any control system requires thermal protection (fuse links) at the valve, at the remote control point and, if necessary, near the hose connections. The Instruction Manuals for Emerson™ actuator systems show how to install the fuse links. Installation instructions on Fisher® Types P650, P163A and P164A cable controls, are in Document D450012T012.

All operating controls should be inspected and cleaned and oiled. The controls should be checked to see that they fully open—but not over-travel—the internal valve operating lever and operate freely to close the valve. 4. Standard construction internal valves must be removed if the container is to be steam cleaned.
