Double Seat Mix Proof Valves
Instruction Manual: US - rev. 1
Waukesha Cherry-Burrell®brand D4 / D4 SL Schedule 5 Valves
4. Mode of Operation
4.1. General terms
Due to its construction and mode of operation as well as to the use of
high quality stainless steel and adequate seal materials, the D4
and D4 SL double seat mix proof valves are suited for applications
in the food and beverage industries as well as in pharmaceutical and
chemical applications.
- The D4 and D4 SL valves separate two line passages by two balanced
and independently operating valve shafts with an intervening leakage
chamber.
- The valve opens from the top to the bottom in a low-leakage design.
- Leakages are discharged via the drain pipe (E) in depressurized state.
- The pneumatic actuator opens the valve via the air connection (1). The
springforceresetsthevalveintothe“closed”safeposition.
- The standard D4 valve is equipped with a non-seat lift actuator and a
CU41 control unit.
- The standard D4 SL valve is equipped with an actuator including seat
lift function and a CU43 control unit.
- D4 SL valve:
Cleaning of the seat is controlled via the air connections.
2 = to lift upper shaft
3 = to lift lower shaft
- The spray connection (C) cleans the leakage chamber.
- As an option, the closed and open positions of the D4 and D4 SL can
be detected via proximity switches.

4. Mode of Operation
4.2. Valve in "closed" position
The lower and upper valve shaft are in closed position and safely
separate the different liquids A and B. The leakage chamber L, which is
situated between the two valve shafts, provides for a free and depres-
surized discharge to the bottom. The valve shafts are balanced and
protected against pressure hammer.
4.3. Valve in "open" position
The upper valve shaft is pressed against the seal of the lower valve
shaft by control of the actuator.
First, the leakage chamber L is closed against the product chamber.
Then the two valve shafts move downwards into the open position. The
connection between the two pipelines A and B is established.

5.2. Valve position indication
Proximity switches to signal the closed and open position of the valve
can be installed at the proximity switch holder.
We recommend using one of these standard types:
three-wire proximity switch
operating distance: 0.196" (5 mm)
diameter: 0.433" (11 mm)
operating voltage: 10–30 V DC
pnp pulse-shifting, closing function
"non-ush"installation
Recommendation:
Proximity switch 24V DC, PNP, 11 mm DIA. (5 m cable): H16223
Proximity switch 24V DC, PNP, 11 mm DIA. (cable box): H16432
Note: If the customer decides to
use valve position indicators other
than those listed, SPX FLOW can-
not assume any liability for the
functionality of the valve.

6. Cleaning
In the cleaning process of the valves, distinction is made between the
following areas: Flow areas, Seat area, and Leakage chamber.
6.1. Flow area
The CIP-fluid cleans the upper and lower passages of the valve during
CIP.
6.2. Seat area - D4 SL valve (chapters 6.5. and 6.6.)
The seat area and leakage chamber are cleaned through lifting of the
individual valve shafts during cleaning of the respective passage.
6.3. Seat area and Leakage chamber
CIP spraying cleans the seat area and the leakage chamber. The clean-
ing connection is at item C in fig. 6.3.
D4 valve: CIP spraying must generally be undertaken.
CIP spraying does not produce pressure build-up in the leakage cham-
ber. SPX FLOW recommends performing CIP-spraying in the closed
valve position; however, it can also be done in the open valve position.
Under standard conditions 15 valves size 2" Sh5 - 3" Sh5 or 10 valves
size4”Sh5-6”Sh5canbecleanedviaonespraydistributionline1".
6.4. Cleaning recommendation

subsequent flushing 2 x 5 sec. 2 x 10 sec.
-D4 SL Valve: The lifting cycles refer to a cleaning pressure of
p = 29 - 72 psi (2-5 bar).
- Depending on the pressure ratio, cleaning temperatures, cleaning steps
and degree of soiling, time and number of cycles must be adjusted.
- Flushing quantities per CIP spraying cycle:
2" Sh5 - 3" Sh5 about 0.32 US gal/10s (1.2 ltr/10s)
4: Sh5 - 6" Sh5 about 1.32 US gal/10s (5.0 ltr/10s)
- Cleaning pressure at CIP cleaning connection:
min. 29 psi (2 bar)
max. 72 psi (5 bar)
Caution!
The cleaning liquid applied must be compatible with the respective seal
material.

7. Installation and Commissioning
- The valve must be installed in vertical position to ensure that fluids can
drain off freely from the valve housing and the leakage chamber.
Caution! Leakages and fluid losses from seat lifting and CIP-
spraying must be safely collected and drained!
- The valve housing can be welded directly into the pipeline (completely
removable valve insert).
Note! Observe welding instructions.
- Observe heights of installation and removal!
Caution!
Before first startup:
- Actuate the valve by applying compressed air. The opening, closing
and shaft lifting processes must run smoothly.
- Check the function of the control unit or valve position indication.
- Check for possible leakages during commissioning. Replace defective
seals.
7.1. Welding Instructions
- Before welding the valve, remove the valve insert from the housing.
Caution! Handle and store the valve insert carefully to avoid damaging
the parts.
2-4" valves: Remove the lower shaft seal and guide ring from the
housing.
6" valve: It is not necessary to remove the lower shaft seal as it
can be damaged during removal.
- Weldingshouldonlybecarriedoutbycertiedwelders(DINENISO
9606-1) (seam quality DIN EN ISO 5817).
- The welding of the valve housings must be undertaken in such a way
that the valve body is not deformed.
- The preparation of the weld seam up to 0.12" (3 mm) thickness must be
carried out as a square butt joint without air. Consider shrinkage!
- TIG orbital welding is recommended.
-Caution! Afterweldingthevalvehousingormatinganges,andafter
performing any work on the piping, do not operate the valves until the
corresponding areas of the installation and piping have been cleaned
and welding residue has been removed. If the piping is not cleaned
before operation, welding residue and dirt particles can settle in the
valves and cause damage to the valves and seals.
- If these welding instructions are not followed, any resulting damage will
not be covered by the warranty.
- Welding directives for aseptic applications shall be drawn from the
AWS/ANSI Directives and EHEDG Guidelines.

The maintenance intervals are different depending on the application
and must be determined by the operator performing regular checks.

substances. Abrasive and polishing agents are especially harmful to the
upper and lower shaft.
Required tools for standard maintenance:
- 1 x wrench SW13, SW24, SW30, SW32
- 1 x wrench SW36
- 2 x wrench SW17
- 1 x Allen key SW3, SW6
- longhookwith45°tiporlongnosepliers
- pick tool for O-ring and rubber seal removal
- double joint forceps
- assembly stick D4 for assembly of lower shaft seal, see page 23
- disassembly and assembly tool for lower shaft seal, see page 23
- assembly tool for middle seal, see page 24
- assembly tool for seat seals, see page 25
- 2 long M8 hex screws for safe removal of valve insert
- For valve maintenance SPX FLOW offers complete seal kits (see spare
parts lists).

The item numbers refer to the spare parts drawings in section 15,
starting on page 27.
For Disassembly/Assembly tools, see chapter 13.
11.1. Removal from the line system
Caution!
1. Shut off the line pressure in the product and cleaning lines, and
discharge the pipes if possible.
2. Remove the compressed air lines from the valve actuator (17).
3. Release the 2 screws at the clamp rings and lift the control unit off the
adapter.
4. Design with proximity switch holder:
Release the screws at the proximity switch holder and lift off the
proximity switch holder.
5. Remove the flange screws (27) in the yoke (6). For additional safety,
replace two flange screws with longer screws that are partially threaded
into the flange. Once these longer screws are in place, the other two
flange screws can be safely removed.
6. Screw one flange screw (27) into the threaded bore of the yoke (6) to
lift the complete valve insert. Do not remove the screw. It helps to re-
install the valve insert.
7. Carefully lift the valve insert vertically out of the valve housing (1).
