1.2 Explanation of the signal words
Different signal words in combination with warning signs are used in this
operating manual. Signal words illustrate the gravity of possible injuries if
the risk is ignored:
Signal word Meaning
DANGER Refers to imminent danger. Ignoring this sign may
lead to death or the most serious injuries.

2 General
2.1 General warnings
The following warnings are intended to help you to eliminate the dangers
that can arise while handling the product. Risk prevention measures al-
ways apply regardless of any specific action.
Safety instructions warning against risks arising from specific activities
or situations can be found in the respective sub-chapters.
WARNING
Danger from unsuitable materials
The materials of the dosing pump and hydraulic parts of the system
must be suitable for the dosing medium that is used. Should this not be
the case, the dosing media may leak.
ðMake sure that the materials you are using are suitable for the
dosing medium.
ðMake sure that the lubricants, adhesives, sealants, etc. that you
use are suitable for the dosing medium.
ðWear appropriate personal protective equipment, especially for
the protection of eyes and skin.
CAUTION
Danger when changing the dosing medium!
Changing the dosing media can provoke unexpected reactions, dam-
age to property and injury.
ðClean the dosing pump and the system parts in contact with the
media thoroughly before changing the dosing medium.
2.2 Hazards due to non-compliance with the safety
instructions
Failure to follow the safety instructions may endanger not only persons,
but also the environment and the device.
The specific consequences can be:
ndanger for individuals through dangerous dosing media,
ndanger to the environment caused leaking from the system.
2.3 Personal protective equipment
Based on the degree of risk posed by the dosing medium and the type of
work you are carrying out, you must use corresponding protective equip-
ment. Read the Accident Prevention Regulations and the Safety Data
Sheets to the dosing media find out what protective equipment you need.
You will require the minimum of the following personal protective equip-
ment:
Personal protective equipment required
Protective goggles
Protective clothing
Protective gloves
Table 3: Personal protective equipment required
Wear the following personal protective equipment when performing the
following tasks:
nInstallation,
nShut-down,
nMaintenance work.
2.4 Personnel qualification
2.4.1 Specialist staff
Thanks to their professional training, knowledge, experience and knowl-
edge of the relevant specifications, specialist staff are able to perform the
job allocated to them and recognise and/or eliminate any possible dan-
gers by themselves.
2.4.2 Personnel tasks
In the table below you can check what qualifications are the pre-condi-
tion for the respective tasks. Only people with appropriate qualifications
are allowed to perform these tasks!

Multi-function valve PENTABLOC Operating instructions
3 Intended use
The Multi-function valve PENTABLOC includes various functions and ful-
fils the following tasks:
nThe pressure retaining function to optimise dosing accuracy.
nThe anti-siphon function avoids undesired siphoning.
nThe safety function protects the dosing pump and the connected
system against excess pressure.
nOption for pressure-relief in the delivery line by returning the medium
to the supply tank.
nDosing control from a bouncing ball in a transparent viewing tube.
Intended purpose
The Multi-function valve PENTABLOC ensures the exactness of dosing
pumps with fluctuating back pressure, especially in the area with a pres-
sure of 0 to c. 1 bar. When dosing in unpressurised systems, the inertia of
the accelerated fluid leads to overdosing. As such, the dosing pumps
must be protected against too high a level of pressure, in order to be able
to dose the exact quantity.

4.3 Functions

F
M
K
Fig. 2: Function of the back-pressure valve
The back-pressure function is achieved when a medium entering at in-
put(A) presses against the diaphragm(M). The spring(F) of the left-hand
grip(L) is moved from a pressure of c. 1.5 or 3 bar. The medium can flow
to output(B).
The intermittent media flow entering the dosing pump causes the ball(K)
to jump visibly.
4.3.2 Anti-siphon function
B

F
M
Fig. 3: Function as an anti-siphon valve
The Pentabloc serves as an anti-siphon valve. The design prevents the
medium from flowing in an uncontrolled fashion, whether through an op-
erational vacuum or resulting from a siphon effect.
4.3.3 Pressure-relief function
C
A
R
F
M
K
Fig. 4: Function as a pressure-relief valve
The Pentabloc serves as a safety valve, if the system pressure exceeds 5
or 11 bar. In this case, the medium presses against the diaphragm (M)
and the spring of the right-hand grip (R) concedes. This medium can flow
to the output for the return (C) and is led into the dosing medium contain-
er via a return hose.
4.3.4 Pressure relief function

Fig. 5: Function for system pressure relief
The Pentabloc has a function to relieve the piping system when the pump
is not working. To do so, pull both handles outwards at the same time.The
medium can flow out of the output to the return through a return hose into
the dosing medium container.
