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 double-seat mixproof valve DELTA DE3 is suited
for applications in the food and beverage industries as well as in
the pharmaceutical and chemical industries.
The valves are designed for universal applications and stand out
for their increased mechanical reliability and absolute ease of
service.
The valve opens from the top to the bottom in low leakage
operation (unpressurized drain of fluid residues via the annular
cleaning gaps in the seat area).
Separation of two line passages by two balanced and
independently operating valve slides with intervening leakage
chamber. Flushing connection at (B1).
Double sealing function by two seals acting independently of
one another.
Arising leakages at the seat seals are discharged at (C) in
depressurized state.
Proximity switches can be installed at the main cylinder as valve
position indicators. (fig. 4.1.)
Operation by pneumatic actuator with air connection at (A). Reset
by spring force into the safety limit position "closed".
Main cylinder can be maintained.

4. Mode of Opeartion
4.2. Valve in "closed" position
The lower and upper valve shafts are closed by spring force
and safely separate the different uids Aand B. The leakage
chamber Lwhich is situated between the two valve shafts,
provides for a free and absolutely depressurized discharge to
the bottom. The valve shafts are balanced and, thus, safe against
pressure hammers.
4.3. Valve in "open" position
During the opening process, the leakage chamber Lis closed
against the product area and the pipelines Aand Bare connected.
In open valve position, the valve shafts are also balanced and,
thus, safe against pressure hammers.

5. Auxiliary Equipment
5.1. Valve position indication
Proximity switches to signal the limit positions of the valve shafts
can be installed at the main cylinder if required (fig. 5.1.)
D1 = valve position "closed"
D2 = valve position "open" (only for DN 40 - 50, 1,5” - 2”)
D3 = valve position "open" (only for DN 65 - 150, 2,5” - 6”)
We recommend to use our APV standard types:
operating distance: 5 mm / diameter: 11 mm
If the customer decides to use valve position indicators other than
APV type, we cannot take over any liability for a faultless function.
5.2. Control Unit
The installation of a control unit on the DE3 valve is possible.
Start-up, assembly and dismantling of the different designs are
described in the corresponding instruction manual.

6. Cleaning
Cleaning DELTA DE3 valves, one has to distinguish between
three areas:
6.1. The flow areas
The upper and lower passages are cleaned by the passing
cleaning liquid during the cleaning of the connected pipelines.
6.2. The lekage chamber (fig. 6.2.)
The cleaning of the leakage chamber is undertaken by CIP
spraying. CIP cleaning connection (B1).
CIP must generally be undertaken.
Spraying does not produce pressure build-up in the leakage
chamber and can be carried out in closed and in open
valve position.
The conduct of the cleaning liquid provides for perfect cleaning
of the whole leakage chamber.
Under standard conditions
15 valves DN 40 - 100, 1,5" - 4"
10 valves DN 125 - 150, 6” can be cleaned
via one spray distribution line DN 25.
6.2.1. Cleaning recommendation on intervals and spraying liquids
under standard operating conditions and with common
CIP liquids
cleaning step CIP cycle
pre-flushing 3 x 10 sec.
caustic flushing 80° C 3 x 10 sec.
intermediate flushing 2 x 10 sec.
acid flushing 3 x 10 sec.
subsequent flushing 2 x 10 sec.
Depending on the pressure ratio, cleaning temperatures and the
degree of soiling, different cycles must be adjusted.
The compatibility of the individual cleaning processes and liquids
with the respective seal materials must be veried.
7.2.2. Flushing quantities:
per CIP cycle DN 40 - 100, 1,5” - 4” about 1.2ltr. / 10s
DN 125-150, 6" about 5ltr. / 10s
7.2.3. Cleaning pressure at
CIP cleaning connection (B1): min. 2bar
max. 5bar

6. Cleaning
6.3. Shaft surfaces outside the flow passages (option)
The DE3 valve provides for the areas of the upper and lower
shaft rod which are not subject to cleaning, to be flushed (fig. 6.3.).
The valve is prepared for shaft flushing.
(see chapter 15).
Shaft flushing is recommended with sensible products to
increase product safety and the service life of seals.
The connection of the flushing device is done according to the
pattern described on the left via flushing connections.
6.3.1. Flushing and sterilisation of shaft surfaces
The following flushing liquids are permissible:
- hot water
- (slightly sour to avoid lime residues): max. 85oC
- common CIP liquids: max. 80oC
supply pressure at CIP cleaning
connection: min. 1 bar
max. 3 bar
flushing quantity per CIP cycle: about 1.2ltr. / 10s
cleaning period: 30s
interval: 1x / day (e.g. milk)
depending on product and
operating frequency: 1x / week (e.g. beer)
The free discharge of cleaning liquids must be ensured.
The upper and lower shaft flushing may only be carried
out if product is not imminent in the appertaining part of the
housing.
6.3.2. Installation of hoses:

7. Installation
7.1. General terms
- The valve must be installed in vertical position. Fluids are, therefore,
freely drainable from the valve housing and the leakage chamber.
- Valve housings can be welded direct into the pipelines (completely
dismantable valve insert).
-Attention: Observe welding instructions.
- Heights of installation and dismantling (see chapter 9).
7.2. Welding Instructions
Before welding of the valve, the valve insert must be dismantled
from the housing. Careful handling to avoid damage to the parts
is necessary (see 12.1.5).
It is not necessary to remove the lower shaft seal as it can be
destroyed during dismantling.
Welding must only be carried out by certified welders (DIN EN ISO
9606-1). (Seam quality DIN EN ISO 5817).
Welding 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 3 mm thickness shall be
carried out as a square butt joint without air. Consider shrinkage!
- TIG orbital welding is best!
After welding of the valve housing or of the mating anges and
after work at the pipelines, the corresponding parts of the
installation and pipelines must be cleaned from welding residues
and soiling before operation of the valves to avoid damage to the
valves and seals.
If these cleaning instructions are not observed, welding residues
and dirt particles can settle in the valve and cause damage.
- Any damage resulting from the non-observance of these welding
instructions is not subject to our guarantee.
- Welding directives for aseptic applications shall be drawn from the
AWS/ANSI Directives and EHEDG Guidelines.

11. Maintenance
- The maintenance intervals depend on the application and should be
determined by the user carrying out regular checks.
- Compressed air is not required to dismantle the valve.
Required tools:
- 1 x spanner SW13
- 2 x spanner SW17
- 2 x spanner SW24
- disassembly and assembly support for the lower shaft seal
ref.-No. 000 51-13-100/1; H171889
- Replacement of seals according to Service Instructions.
The customer is recommended to hold spare seals on stock.
For valve maintenance SPX FLOW supplies complete seal kits
including seal grease (pl. see spare parts lists).
- The valve must not be cleaned with products containing abrasive
or polishing substances. Especially the valve shafts must not be
cleaned with such agents under any circumstances. Damage of the
valve shaft can produce leakages.
- Assembly of the valve according to Service Instructions.
All seals must be provided with a thin layer of grease before
their installation. (see lubrication chart)
Attention! Use only food-grade special grease being
suited for the respective seal material.
Recommendation:
APV assembly grease for EPDM, HNBR , FPM
(0,75 kg /tin - ref.-No. 000-70-01-019/93; H147382)
(60 g /tube - ref.-No. 000-70-01-018/93; H147381)
! Do not use grease on mineral oil basis for EPDM seals.
Recommendation for actuator (main cylinder):
APV pneumatic grease:
(25 ml / tube - ref.-No.: 000-70-01-008/93; H164725)
Less suited grease types can influence function and lifetime.
