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.
6 DV-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.
