1.1 Safety
These Installation and Operation Instructions must be observed
and applied at all times along with the general “VAG Installation
and Operation Instructions for Valves” (see www.vag-group.com/
Category: Installation and Operating Instructions).
Arbitrary alterations of this product and the parts supplied with it
are not allowed. VAG does not assume any warranty or liability for
consequential damage arising from non-compliance with these
instructions. When using this valve, the generally acknowledged
rules of technology have to be observed (e.g. DIN standards,
DVGW guidelines, VDI directives, etc.). The Penstock must only
be installed by qualified, specially trained staff. For further techni-
cal information such as dimensions, materials or applications,
please refer to the respective documentation (KAT-A 2452).
VAG valves are designed and manufactured to the state of the art
and their safety of operation is ensured in general. However,
valves may be potentially dangerous if they are operated impro-
perly or are not applied for the intended use.
Everyone dealing with the assembly, disassembly, operation,
maintenance and repair of the Penstock must have read and un-
derstood the complete Operating and Maintenance Instructions
(Accident Prevention Regulations, VBG 1 §14 ff [Regulations is-
sued by the Trade Associations].
The pressure in the pipeline section must be relieved and hazards
must be eliminated before protective devices are removed and/or
work is performed on penstocks. Unauthorised, unintentional and
unexpected actuation as well as any hazardous movements
caused by stored energy (pressurised air, water under pressure)
must be prevented.
For equipment for which monitoring is mandatory, the relevant
laws and regulations such as the Industrial Code, Accident Pre-
vention Regulations, Boiler Inspection Regulations, AD Data
Sheets (AD = Boiler Study Group) etc. must be complied with. In
addition to this, local accident prevention regulations must be
complied with.
For customised models of the VAG EROX

Penstock, please
read the order-related instructions which may be included sepa-
rately and/or are included in the order documentation.
Arbitrary alterations of this product, the parts and accessories
supplied with it are not allowed. VAG does not assume any liabili-
ty for any hazards and damage resulting from the improper use of
the product and from non-compliance with the instructions con-
tained in this document.
1.2 Proper use
The VAG EROX
®
plus
Penstock is a shut-off and modulating
valve for use in wastewater systems.
Its standard version is suitable for sealing pipelines and openings
in constructions (depending on the nominal diameter) up to a
pressure of 10 m water column (1.0 bar) and for modulating the
flow rate. The pressure-rate is valid for both direction.
For the respective technical application ranges (e.g. operating
pressure, medium, temperature) please refer to the product-rela-
ted documentation (KAT-A 2452).
Any deviating operating conditions and applications require the
manufacturer‘s prior written consent!
These Installation and Operation Instructions contain important
information on the safe and reliable operation of the VAG
®
plus
Penstock.
Compliance with these Installation and Operation Instructions
helps:
• to prevent hazards,
• to reduce repair costs and down-times of the Penstock and/or
the entire equipment,
• to improve the operational safety and useful life of the equip-
ment.
1.3 Identification
According to DIN EN 19 all valves bear an identification label spe-
cifying the nominal diameter (DN), nominal pressure (PN), body
material and the manufacturer’s logo.
A rating plate is attached to the body and contains at least the fol-
lowing information:
VAG
Manufacturer’s name
DN
Nominal diameter of the valve
PN
Nominal pressure of the valve
Serial number of the valve and Date of manufacture
2 Transport and storage
2.1 Transport
For transportation to its installation site, the Penstock must be pa-
cked in stable packaging material suitable for the size of the Pen-
stock. The container also needs to ensure that the Penstock is
protected against weather influences and damage. When the
Penstock is transported over long distances (e.g. overseas) and
exposed to special climatic conditions, it needs to be protected
by sealing it in plastic wrapping and adding a desiccant.
Any assemblies must be protected against damage by external
influences during transport and storage.
The VAG EROX

Penstock must be transported lying flat on
its rear side and in almost closed position (cf. Picture 1). Special
varieties and Penstocks in nominal sizes which due to their overall
size cannot be transported in a lying position will be delivered in a
special transport rack.
When actuators are mounted to the bridge of the Penstock, safe
bearings for the actuators need to be provided to prevent the
joints from being exposed to shunt loads.
For transport purposes and also to support assembly, lifting de-
vices such as cables and belts must always only be attached to
the bridge of Penstock (see Picture 1). The actuator, which may
have been assembled, is not suitable for this purpose. The length
