This operating manual has to be read carefully and observed by
the competent operating and maintenance personnel.
We have to 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!
- Before any maintenance work, the line and cleaning system must
be depressurized.
- Observe service instructions for a safe maintenance of the valve!
3. Mode of Operation
I. Manual operation (PR2-HF)
The valve is actuated by turning the handle (B).
turn left = open
turn right = closed.
II. Pneumatic operation (PR2-FS-H)
Through the compressed air supply at "A", the valve is driven into
the "open" position. Reset is done by spring force.
The valve is equipped with an emergency handle (B) which allows
opening and closing by manual operation.
turn left = open
turn right = closed.

* Valve position indication
A switch to signal the limit position of the valve shaft (On/Off) can
be mounted in the yoke area (C) if required.
* Steam-resistant housing (DN 25)
This housing is available for both valve actuations and is welded
direct to the tank or pipeline. It has connections for the steam inlet
and outlet.
5. Cleaning
- With the standard designs, the valve is cleaned during the pipe
cleaning process.
- By short-term interval-opening of the valve, the contact surface
between the valve shaft and the seat is cleaned, whereas liquid
drains off the sampling nozzle (D).
- The valve with steam connection is cleaned and sterilized through
the connecting tubes.
6. Installation
- The installation of the valve must be undertaken in such a way
that liquids can drain off the valve housing.
- The steam-resistant valve must be mounted in horizontal position.
The connecting tubes must be to the top and to the bottom.
- The standard valves can be welded into the pipelines either in
vertical position (sampling connection to the bottom) or in
horizontal position.
-Attention! Observe welding instructions.

- Before welding of the valves, the valve insert must be dismantled
from the housing. See to a careful handling to avoid damage.
- Welding may only be carried out by certified welders (EN 287-1).
(Seam quality EN 25817 "B").
- The welding of the valve housing must be undertaken in such a
way that deformation strain cannot be transferred from the outside
to the valve body.
- The preparation of the weld seam up to 3 mm wall thickness must
be carried out in butt manner as a square butt joint without air.
(Consider shrinkage!)
- TIG orbital welding should be preferred.
- 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 settle in the valve and cause
damage.
- Any damage resulting from the nonobservance of these welding
instructions is not subject to our guarantee.
7. Maintenance
- The maintenance intervals are different depending on the
application and are to be determined by the operator himself
carrying out temporary checks.
- Complete seal kits for the valve service are available
(see spare parts lists).
- Exchange of seals according to service instructions.
- Provide all seals with a thin layer of grease before their installation.
Recommendation:
APV food-grade grease for EPDM,HNBR and FPM
(750 g /tin - ref.-No. 000 70-01-019/93)
(60 g /tube - ref.-No. 000 70-01-018/93)
or
APV food-grade grease for VMQ
(60 g /tin - ref.-No. 000 70-01-017/93)
(60 g /tube - ref.-No. 000 70-01-016/93).
! Do not use grease containing mineral oil for EPDM seals !
! Do not use Silicone-based grease for VMQ seals !
- Assembly of the valve according to service instructions.
