891 Series Flat Bottom Loading Adapter
Instruction & Maintenance Manual

Product Description

Civacon’s 891 flat bottom API adapter design reduces product retention and
increases flow while unloading. The ergonomic handle smoothly opens the
poppet during manual operation and the hardened nose is rotatable for longer
service life. The poppet seal is easily serviced without removing the API from
the truck. The 891 adapter conforms to API 1004 and EN13083 regulations.
Civacon’s 891 is a direct replacement for the 861, 897 and all competitors’

Manual

This manual contains the inspection, maintenance schedule and instructions
for repairing and replacing parts for all the 891 API adapters. The following
schedule, based on the environmental conditions in the northern United States,
is only a recommendation: Inspection and maintenance intervals must be
adjusted according to use and operating conditions. If any parts are damaged,
refer to the Annual Inspection and Maintenance section.

RevF Mar 2019

Semi-Annual Inspection

Visually inspect and test the valve for proper operation. This inspection can be done
without removing the API from the trailer. Before the inspection, ensure that all lines are
empty. Follow all safety procedures. If any of the following parts need to be repaired or
replaced, refer to the Annual Inspection & Maintenance section.

Visual Inspection

1. Inspect the nose external sealing surface for dents or

gouges which could interfere with interfacing equipment

or cause leaks. See Figure 2.

2. Inspect the backside of the nose (as shown in Figure

3) for excessive wear from the loading coupler. Its hard

coated surface should be free of gouges and grooves
which could cause leaks. If gouges and grooves exist, the
adapter end should be rotated or replaced. Inspect the
inside sealing surface (as shown in figure 3) for wear.

3. Inspect stop pin for excessive wear or damage. The

handle should remain in the open position when placed
on top of the stop pin. If the valve does not remain open

because the stop pin is worn, replace the pin. The gap
between the stop pin and handle should be at least 3/16”
(4.87mm) as shown in Figure 4.

Physical Inspection

1. Use the handle to open and close the API several times.

The handle should move smoothly.

2. Open the API with the handle as if unloading. Release

the handle from the latched position allowing the poppet
to slam shut. The poppet should close and center itself.

3. Open the valve by pushing on the poppet with a soft

nonmetallic tool as far off center as possible and allow the
poppet to slowly close. Repeat several times, the poppet
should center and re-seat every time.
