1.0 INSTALLATION
1.1 BONNET ASSEMBLY TO BODY INSTALLATION
This section to be followed when assembling a bonnet
assembly including diaphragm and backing cushion to
a valve body.
1.1.1 Prior to assembly to the body, the
diaphragm/backing cushion should be resting flat
against the bonnet flange. The compressor should be
extending just short of the full closed position. Rotate
the input shaft to achieve this position.
1.1.2 Position the bonnet over the studs and onto the
body. Drop washers over the studs.
1.1.3 After the bonnet assembly is positioned over the
studs and rests against the body, lightly lubricate the
studs with Chevron Poly FM2 just above the bonnet
flange (i.e. the location at which the nut will engage the
stud when tight against the bonnet).
1.1.4 Assemble nuts finger tight. Final tightening of
bonnet fasteners shall be done by hand. Pneumatic
tools are not permitted. Bring the torque up gradually
with at least 3 passes on each nut. Nuts shall be
tightened in a crisscross pattern, so as to compress
the diaphragm evenly. Tighten nuts securely to 10
ft-lbs (120 in-lbs, 13.5 N-m).
!CAUTION
l
Nut assembly torque requirement of 10 ft-lbs
(120 in-lbs, 13.5 N-m) is critical to the success
of the valve's sealing function. Excessive
torque decreases the valve's sealing function
and increases the amount of effort required to
actuate the valve.

1.2 TOTE VALVE TO TOTE TANK INSTALLATION
This section to be followed when assembling a
tote valve to a tote tank.
1.2.1 Prior to pressurization (with the valve
slightly open), verify the torque applied to the
bonnet to body nuts per Section 1.1.4.
1.2.2 Assembly of tote valve to tote tank requires
an o-ring be located in the flange to create a seal
as shown below. This o-ring (#336) is to be
provided by the user to insure chemical
compatibility.
1.2.3 Position the tote valve over the studs mounted in the
tote tank’s flange. Make sure that the valve’s outlet port
does not extend beyond the footprint of the tote tank.
1.2.4 Secure the tote valve to the tote tank using washers
and nuts. Washers and nuts are to be provided by the
user to insure chemical compatibility. Tighten nuts per
user’s torque specification.
1.3 Maximum valve operating pressure is 14 psig (0.97
bar) at 100% pressure drop (DP). A pressure drop of
100% DP is when pressure is only acting on one side of
the diaphragm when the valve is closed and the outlet is
open to atmospheric pressure.
1.4 Cam-Lok cap/cover is to be placed on the valve’s
outlet port when the tote tank contains fluid. This Cam-Lok
cap/cover is to be provided by the user to insure chemical
compatibility.
2.0 OPERATION
2.1 The valve is closed with a quarter turn (90°)
clockwise rotation of the input shaft, opened with
a counterclockwise rotation. The valve is only
intended for manual actuation. Do not attempt to
exceed the quarter turn (90°) rotation limit. A
lever/handle capable of mating with the 0.50”
(12.7 mm) square drive on the valve’s input shaft
is to be used. This lever/handle is to be provided
by the user. It is recommended that this
lever/handle be at least 14” (355.6 mm) long.
2.2 Properly support the lever/handle against the
input shaft during actuation as shown below. Lack
of support may allow the lever/handle to
disengage from the input shaft during actuation
which can cause damage to the input shaft’s
square drive.

2.3 The valve position is visible based on the position
of the groove at the end of the input shaft and lock
plate as shown below.
3.0 MAINTENANCE
2.4 The valve shall lock itself in the open or closed
position. If a secondary lock is desired in the open or
closed position, a pin, tie-wrap or other suitable
securing device may be placed thru the locking plate’s
and bonnet half’s ¼” (6.35 mm) thru hole.
ALL MAINTENANCE PROCEDURES MUST BE
PERFORMED BY QUALIFIED PERSONNEL.
MAINTENANCE DONE BY PERSONNEL NOT
QUALIFIED TO PERFORM IT COULD RESULT IN
PERSONAL INJURY, DEATH OR PROERTY
DAMAGE.
3.1 PERIODIC INSPECTION
!WARNING
s
When the process fluid is hazardous or
corrosive, extra precautions should be taken.
The user should employ appropriate safety
devices and should be prepared to control a
leak of the process fluid. Failure to follow these
instructions could result in serious personal
injury or death, and property damage.
3.2 BONNET TO BODY INTERFACE LEAKAGE
If leakage occurs at the body/diaphragm seating area,
immediately depressurize system, open valve slightly
and tighten nuts per Section 1.1.4. If leakage
continues, diaphragm replacement is required per
Section 3.6.
!WARNING
s
Remove all line pressure.
Periodically inspect condition of external valve parts.
Replace all parts showing excessive wear or
corrosion. Contact manufacturer at the address listed
on the back page of this manual in order to obtain
replacement parts or for specific instructions.
3.3 BONNET ASSEMBLY LEAKAGE
If leakage is occurring thru the bonnet assembly the
diaphragm has ruptured and must be replaced per
Section 3.6.
6DV-1/4 Turn IOM - 11/06
Page 7
3.4 LEAKAGE THRU THE OUTLET WHEN CLOSED
If leakage is occurring thru the body’s outlet when the
bonnet assembly is in the closed position the
diaphragm may be worn. The diaphragm must be
replaced per Section 3.6.
3.5 EXCESSIVE TORQUE TO ACTUATE VALVE
If more than 60 ft-lbs (81.3 N-m) of torque is required
to actuate the valve verify that the bonnet nuts are
tightened to a torque of 10 ft-lbs (120 in-lbs, 13.5
N-m).
3.6 DIAPHRAGM REPLACEMENT
Elastomer diaphragms are not intended to be used
with the quarter turn tote valve. Replacement
diaphragm should be identical in size and grade as
the original diaphragm.
3.6.1 Remove pressure/fluid from the tote tank
containing the valve. The diaphragm can be replaced
with the valve on the tank or after removing the valve
from the tote tank if desired.
3.6.2 Partially opened the valve by rotating the input
shaft counterclockwise. This will ease the pressure
being exerted by the compressor holding the valve
diaphragm to the body weir.
3.6.3 Remove the bonnet nuts. Lift bonnet assembly
from valve body. If the valve is mounted to the tank
support the bonnet assembly as the nuts are
removed.
3.6.4 Unscrew diaphragm from compressor by turning
counterclockwise. Note: Fine bronze shavings may be
present in the bonnet assembly due to component
wear. Clean out these shavings once diaphragm and
backing cushion are removed.
!!CAUTION
l
Nut assembly torque requirement of 10 ft-lbs
(120 in-lbs, 13.5 N-m) is critical to the success
of the valve’s sealing function. Excessive
torque decreases the valve’s sealing function
and increases the amount of effort required to
actuate the valve. If the proper amount of
torque is applied to the bonnet nuts but the
valve requires excessive torque to actuate
contact manufacturer at the address listed on
back page for specific instructions.
3.6.5 Replace backing cushion and plastic PTFE
diaphragm. Note: To engage the threads of the
diaphragm stud invert the plastic PTFE diaphragm. To
invert the diaphragm, press on the center of the
diaphragm face with thumbs while holding the edge of
the diaphragm with fingers.
3.6.6 Screw new diaphragm into compressor by
turning hand tight. Then back off until holes in
diaphragm and bonnet flange line up.
!!CAUTION
l
Do not overtighten diaphragm.
3.6.7 Assemble the bonnet to the body per Section
1.1.
Only Chevron Poly FM2 (silicone free) lubricant is
permitted on the tote valve's body studs. These are
the only components where lubricant is permitted on
the valve assembly. No lubrication shall be used in
the assembly of the quarter turn bonnet. No
lubrication shall be used on the diaphragm.
Bonnet assembly is not intended to be disassembled
nor assembled in the field. Contact manufacturer at
the address listed on the back page for specific
instructions.
