!WARNING!
Failure to follow these instructions or to properly install and maintain this
equipment could result in an explosion and/or fire causing property
damage, personal injury or death.
MEC equipment must be installed, operated, and maintained in
accordance with federal, state, local codes and manufacturer's
instructions. The installation in most states must also comply with NFPA
No. 58, and ANSI/CGA G-2.1.
For installation in the European Union, the equipment must also comply
with PED/TPED and EN ISO standards. Periodic inspections, intermediate
inspections and exceptional checks of transportable pressure equipment
should be carried out in accordance with the Annexes of Directive
2008/68/EC and with 2010/35/EU Directive (TPED) to ensure continued
compliance with their safety requirements.
Only personnel trained in the proper procedures, codes, standards, and
regulations of the LP-Gas or NH3should install and service this equipment.
WARNING: These products contain a chemical known to the
State of California to cause cancer and birth defects or other
reproductive harm.
Installation
!CAUTION!
Make sure all pressure is released from upstream piping before
proceeding with installation.
1. Apply Loctite #565 or suitable thread sealing compound to
male NPT threads of mating fitting or hose end connector.
2. Tighten connection by placing a suitable wrench on the
wrench hex of the ME806-16 Turbo-Flo LE Transfer Valve. If
the hose end connector does not include a swivel, continue
tightening the valve onto the pipe or fitting until the valve is
upright (operating lever facing upward) when installed in final
position.
3. Connect a pressure source of a least 150 psi (1034 kPa) and
check for leaks (as evidenced by bubbles) at all joints and
sealing surfaces, using a suitable leak detector solution at all
joints. Ensure all connection joints are free of leaks before
putting the ME806 LE valve into service.
Operation
!WARNING!
To avoid risk of serious injury or death, never attempt to open the
ME806 Valve when it is under pressure and not properly connected to
transfer system. The ME806 Transfer valve is equipped with a pilot
equalization feature that will discharge a small amount of product if
attempting to open when not properly connected to a transfer
system.
1. Connect the Valve –With pump off, connect the ME806 TURBO-
FLO LE Transfer Valve to an ME868 TURBO-FLO ACME Adapter,
ME807/ME808 TURBO-FLO LE Shut-off valve or other shut-off
valve with standard 3-1/4" female ACME connector; tighten with
appropriate wrench.
2. Open the Valve(s)
a. Ensure the pump is off and the connected Shut-Off valve or
other connection is closed; open the ME806 Transfer valve by
releasing the locking latch and moving the handle toward the
ACME connection.
*Note: A slight motion of the handle opens a pilot orifice that
equalizes pressure on both sides of the valve. Once equalized,
the valve will open fully with continued pressure on the
handle. Once opened, the valve will remain open until the
handle is moved to the closed position (away from the ACME
connection). If the valve does not open fully with reasonable
pressure on the handle, check to make sure the latch is pulled
all the way out of the locking notches in the valve casting and
that the hose-end valve is fully closed.
b. Open the connected inlet shut-off valve or other connection.
3. Transfer Product –Turn pump on and follow safe filling / transfer
practices as outlined in the NFPA 58, national fuel gas code.
*Note: In case of emergency, the ME806 valve can be closed
instantly by snapping the spring loaded handle to the closed
position (away from the ACME connection).

ME806-16 Series
Form #435 Rev D 5/8/19
!CAUTION!
The ME806 valve series is rated for a maximum pressure of 400 psi
and an operating temperature range of -40°F to 212°F (-40°C to
100°C). DO NOT exceed these parameters during valve operation or
use.
4. End Transfer –Turn off pump, then close the ME806 Transfer
valve by pushing the handle away from the ACME adapter until
the handle safety latch locks in the closed position. Close the
inlet Shut-Off valve or other connection next. Disconnect
Transfer valve.
!WARNING!
NEVER disconnect the ME806 Transfer with the valve open. Ensure
the safety latch is in the locked position (both sides of the latch
engaged in notches on body) before disconnecting valve.
*Note: this valve system is designed for minimum product loss at
disconnect. To achieve the intended low emission feature of this
transfer system, you may need to adjust your standard operating
procedure for the filling process. When using the ME868 TURBO-FLO
ACME Adapter in conjunction with ME806 Transfer valve, do not vent
the product trapped between the container service valve and the
adapter.
!WARNING!
To avoid risk of serious injury or death, never attempt to open the
ME806 Transfer Valve when it is under pressure and not properly
connected to the system with an appropriate transfer hose.
Never attempt to remove, replace or service the ball bearings in
the bearing race.
Ensure hydrostatic relief valve is aimed away from people at all
times.
Remove valve from service immediately if any ball bearings come
out of bearing race.
Remove valve from service immediately if the safety latch does not
function properly.
Remove valve from service immediately if valve seals or joints leak.
ACME Nut Service and Replacement Instructions
!WARNING!
Failure to follow the adapter service and replacement instructions
could cause risk of serious injury or death. Adapter Nut replacement
must be performed by qualified service personnel.
1. Release all system pressure before attempting to service the nut.
2. Remove the (2) Set Screws [2] from Body [1] that retain the
Adapter Nut [3] and discard.
3. Remove the Adapter Nut [3] from the Body [1] casting using the
appropriate wrench on the wrench flats provided.
4. Remove Seal [4] from the Body [1] and discard.
5. Clean all threads and sealing surfaces and install new Seal [4] into
Body [1] casting.
6. Apply Loctite #242 (blue) or equivalent thread locker to new
Adapter Nut [3] and torque to 160 to 180 Ft-lbs (217-244 Nm).
*Note: If using an ACME Cap to install, leave Cap in place until after
set screws are installed in step 7.
7. Install new Set Screws [2] and torque to 80 in-lbs (9 Nm)
*Note: Use only the (2) Set Screws [2] provided with service kit.
8. Connect a pressure source of a least 150 psi (1034 kPa) and check
for leaks (as evidenced by bubbles) at all joints and sealing
surfaces by applying a suitable leak detector solution to all joints.

Preventative Maintenance and Safety Checks
The ME806 Transfer Valve is designed to provide a long and trouble
free service life when properly installed and maintained. Like all
mechanical devices, however, it is subject to wear and requires
preventative maintenance to maintain safe and efficient operation.
The valve contains a date of manufacture code, see above.
Perform the inspections and service as follows:
Before each use:
1. Inspect the safety latch to ensure that it is in the locked position
(both sides of the latch engaged in notches on body) prior to and
after each use. If it is not fully latched, move the handle grip
away from the ACME nut until latch is fully engaged.
2. Inspect ACME nut for worn threads. Replace nut assembly if
required. See “Periodic Checks” for important safety
instructions regarding the ACME adapter.
Periodic Checks
The following checks should be performed weekly on valves exposed to
severe service conditions such as frequent use (over 100 connections
per week) or when exposed to contaminants, corrosive agents or
extreme weather conditions. The checks should be performed at least
monthly on all other valves.
1. Adapter Nut Assembly –Inspect the hardened steel bearing races
for wear by checking the gap between the ACME nut race and the
nut adapter race. A gap greater than 0.135” (3.4mm, 2 stacked US
quarters) indicates excessive wear and MUST be removed from
service immediately, see Service and Replacement
2. Handle assembly –Inspect the valve handle, latch and springs for
proper operation. If service is required. Have handle assembly
replaced by qualified service personnel using the service
instructions provided with the replacement parts. Remove valve
from service immediately if the safety latch does not function
properly.
3. Seals –Inspect the valve seals for leaks (as evidenced by bubbles)
at all joints and sealing surfaces by apply Marshall Excelsior ”Leak
Detector” solution to all joints. If service is required, have leak
repaired by qualified service personnel using the service
instructions provided with the replacement parts. Remove valve
from service immediately if valve seals or joints leak.
