1. General Terms
This instruction manual has to be read carefully and observed by
the competent operating and maintenance personnel.
For design reasons, the technical operating ranges of the valve
with regard to operating pressures and temperatures have to
be kept.
We have to point out that we will not accept any liability for
damage or malfunctions resulting from the non-compliance
with this instruction 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 nd it wherever the activities
described are bearing risks of personal injury
- Before any maintenance of the valve, the line system in which the
constant pressure valve is installed, and the air supply must be
depressurized.
- Any leakages arising at the diaphragm are carried off via the
leakage drain. Leakages must be drained off safely and without
risks (e.g. through a funnel). Leakages must be visibly detectable.
Attention!
Observe Service Instructions to ensure safe maintenance
of the valve!
3. Intended Use
The intended use as eld of application of the CPV valve is to keep
process pressures constant in process plants.
Arbitrary, structural changes at the valve may affect safety as well
as the intended functionality of the valve and are not permissible.

4. Application and Mode of Operation
The CPV constant pressure diaphragm valve forms part of the
pneumatically operated pressure regulating valves and pressure
holding valves which keep process pressures constant in process
technological plants of the food and beverage as well as of
the pharmaceutical and chemical industries (e.g. application of
separators, pasteurizers and UHT plants, llers, etc.).
The effective principle of pressure keeping is based on the
diminuation and enlargement of the free ow section at the valve
seat by the valve shaft which is connected with the regulating
diaphragm.
The actuation of CPV valves is effected by compressed air at (F).
Compressed air supply is to be undertaken via a regulating valve
for control air (ne pressure reducer) with integrated aeration. The
product pressure should be controllable by a measuring unit.
Recommendation:
1 = ne pressure reducer - type Manostat, 40 mbar - 8 bar
2 = lter - ≈ 50 μm
Valve variant CPV-o provides for a constant pressure regulation
before the valve. (o = open)
It opens with increasing product pressure and closes with
decreasing pressure.
Valve variant CPV-c provides for a constant pressure regulation
behind the valve. (c = closed)
It closes with increasing product pressure and opens with
decreasing pressure.
Thus, the set value adjusted is kept at a constant level. Through the
use of the product / air diaphragm, intermixing can be prevented
in case of diaphragm rupture due to wear. Leakages are indicated
immediately via the leakage drain.

5. Cleaning
Cleaning of the CPV valves is undertaken with pipeline cleaning.
The following has to be considered for the different valve variants.
Δp of about 3bar must be kept.
Cleaning CPV-o:
- At a max. CIP line pressure up to 3 bar, the valve is not controlled
with pneumatic air. The valve moves into open position.
- If the max. CIP line pressure of 3 bar is exceeded, the valve must
be controlled with pneumatic air pressure,
e.g. ...PCIP = 5 bar, Pair = 2 bar.
Cleaning CPV-c:
- Supply pneumatic air to produce a pressure difference of about
3 bar. The valve moves into open position,
e.g. ...PCIP = 2 bar, Pair = 5 bar.
6. Installation
The CPV constant pressure diaphragm valve is installed as corner
valve in such a way that liquids can drain off in depressurized state.
The installation position must provide for self-draing of the valve.
All valves are equipped with weld ends.
-Attention! Observe welding instructions!

7. Installation
7.1 Welding Instructions
CPV
- Before welding of the valves, the valve insert must be dismantled
from the housing. See to a careful handling to avoid damage to the
parts.
- Welding may 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 effected 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 is best.
- After welding of the valve housings or of the mating anges 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.
- Welding directives for aseptic application shall be drawn from the
AWS/ANSI Directives and EHEDG Guidelines.

(DIN EN 10088)
Screws: 1.4301
(DIN EN 10088)
Seals: standard design EPDM

10. Maintenance
The maintenance intervals depend on the corresponding application
(product, temperature) and are to be determined by the operator
himself carrying out temporary checks.
The following maintenance recommendation must be veried on the
basis of the individual operating conditions. As the valves are often
used in hot applications or are subject to operating frequencies
of more than 30,000 cycles per year, we recommend half-yearly
preventive maintenance.
Replacement of seals according to Service Instructions.
All seals must be greased well before their installation.
The diaphragm must be greased well at the product-averted
side, only!
Recommendation:
APV assembly grease for EPDM
0.75 kg tin - ref.No. 00070-01-019/03; H147382
60 g tube - ref.No. 00070-01-018/93; H147381
Attention!
Do not use grease containing mineral oil for EPDM seals.
