1. General Terms
This instruction manual must be read carefully by the competent
operating and maintenance personnel.
We point out that we will not accept any liability for damage or
malfunctions resulting from the non-compliance with this
operating manual.
Descriptions and data given herein are subject to technical changes.
2. Safety Instructions
Danger! The technical safety symbol draws your attention to
important directions for operating safety. You will
find it wherever the activities described are bearing
risks of personal injury.
-Separate electric and pneumatic connections.
-Depressurize and, if possible, discharge the line and cleaning
system before any maintenance work!
-Observe Service Instructions to ensure safe maintenance of the
valve.
-Do not open the actuator by force! It is under spring tension!
Attention!Valve design NC: Relieve the valve insert by controlling the actuator before releasing the clamp!
3. Intended Use
The intended use as field of application of the AP valve is the
shut-off of line sections.
Arbitrary, constructive changes at the valve will influence safety
as well as the intended functionality of the valve and are not
permissible.

materials, the aseptic process valve APV DELTA AP1 can be used
in the food and beverage as well as in the pharmaceutical and
chemical industries.
The function of the valve is to shut off line sections.
The diaphragm valves offer optimum protection of the product in
hygienic and aseptic applications.
Product safety is provided by the hermetic separation of the
product chamber from the environment (atmosphere) by a
flexible diaphragm shaft.
-Different variants are available:
Type: AP1 - NC (FS) (NC = normally closed;
air-to-raise, spring-to-lower)
Type: AP1 - NO (FH) (NO = normally open;
air-to-lower, spring-to-raise)
Type: AP1 - AA (LL) (AA = air/air actuator)
Type: AP1 - M (H) (M = manual operation)
-Operation by pneumatic stroke actuator with air connection, reset by
spring force.
-The cleaning of the inner area of the valve is undertaken during CIP
cleaning of the line system.
-Leakages at the diaphragm are indicated at the safety indicator
screw at the leakage drain.
-Maintainable actuator.
-Optical valve position indicator on the actuator cover.
-Thepneumaticactuatorcanbeequippedwithanelectricposition
switch (proximity switch) to indicate the current valve position.
-The valve diaphragm shaft is made of TFM material.
-Different housing variants (see spare parts drawings) are available.
-Connections
Beside the housings with weld ends according to DIN 11850 and
ISO 1127 the following connections are available:
-clamp connection according to DIN 32676
-clamp connection according to ISO 2852

6. Installation
-The installation of the valve must be undertaken in such a manner
that fluids can drain off the valve housing and should preferably be
provided in vertical position.
-The valve housing can be welded direct into the pipeline (completely
dismantable valve insert).
Attention! Observe welding instructions.
6.1 Welding Instructions
Shut-off valve AP/APT
-Before welding of the valve, the valve insert must be dismantled
from the housing (see paragraph 11.1.2. - 4.).
Careful handling to avoid damage to the parts is necessary.
-To weld APT valves in tanks, the corresponding dimensions for the
preparation of the tank bore can be drawn from table 1.
-Welding should only be carried out by certified welders DIN EN ISO
9606-1).(seamqualityDINENISO5817).
- The welding of the valve housings must be undertaken in such a
way that the valve body is not deformed.
-Thepreparationoftheweldseammustbecarriedoutasasquare
butt joint without air. (Consider shrinkage!)
-TIG orbital welding is best.
! After welding of the valve housings or of the mating flanges and
after work at the pipelines, the corresponding parts of the
installation or pipelines must be cleaned from welding residues and
soiling. If these cleaning instructions are not observed, welding
residues and dirt particles can damage or destroy the diaphragm
shaft.
-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.
