PENSTOCK RANGE
AVK UK is part of the globally
renowned AVK group who are
based in over 85 countries and
are known as one of the leading
innovators and manufacturers
of high quality valves and fittings
for the water, waste water,
fire fighting and gas industries
worldwide.
The AVK Penstock range are
designed to compliment our
existing Water and Waste Water
offering.
High Quality Manufacture
Quality & Testing
Manufactured in Europe, the AVK penstock
range is designed using Finite Stress
Structural Analysis (FSA) to ensure optimum
rigidity and allowing for modelling that allows
any undesirable deformation to be designed out
pre-production. Products are also subject to FEA
as part of their design.
The sealing performance of the AVK penstock
offer, exceed the requirement of BS7775. This
is assured by hydraulically batch testing for
leak tightness and rigidity and is a feature that
makes the stainless steel penstock superior to
typical cast iron versions.
Computer controlled laser cutting and the latest
robotic welding machines ensure minimal
waste material and correct welding processes minimising deformation across the penstock.
Stainless steel grade 304 or 316 on Duplex
gives maximum corrosion resistance with low
mass for ease of installation.
High quality penstock manufacturers
based in Spain and are a member of
the AVK group of companies

SAFOX Penstock

The Safox* range of
penstocks from AVK is
the premium penstock
offering, giving full sealing
characteristics in a number
of installation options.
Product Characteristics

•
•
Size range : 150 to 2200mm
Full sealing for wall fixing for bi-directional
duty up to 6 meter head with no fixings
below the invert
Superior sealing
Whilst leakage on penstocks is usually
caused by insufficient frame stability
and frame distortion, the patented Safox
system is not affected by such instability
due to the independence of the sealing
from the frame. Due to this independence,
the Safox perfectly seals to the
mounting wall and sliding plate and can
accommodate certain structural variations
Safox Features
The freely suspended sealing ring is self
adjusting and requires no adjustment after
mounting.
Safox penstocks are non-drip leak proof on
under seating and off seating heads up to
6 meter head. If required, the Safox can be
supplied to withstand higher pressure.
The Safox F can be supplied with flange
connection, and the Safox Q for quadrangular
openings is also available on request.
When required, chemical anchor bolts can be
supplied.

WRAS approved seal available for potable
water
The Orbinox model SA Aluminum Stop Log is designed
for open channel installations for temporary isolation and
flow control. Stop Logs are ideal for maintenance and
repair works or flood control and diversion. The logs are
made of extruded aluminum and are very easy to handle
due to their light weight.
Stop log
The logs are stacked on top of each other in the frame
guides. The water level is controlled by adding or
removing logs. The sealing system is bidirectional
(suitable for flows in either direction) and allows to
achieve very low leakage rates.
The frame can be made of aluminum or stainless steel
and it can be designed to be embedded in concrete, wall
mount or face mounted in a existing channel.
The aluminium and
stainless steel stop logs are
designed for open channel
installation.
Product Characteristics
Aluminium stop logs are designed for temporary
isolation and flow control. Stop logs are ideal for
maintenance and repair work on flood control
and reservoirs. The stop logs are made from
extruded aluminium and are easy to handle due
to their:
• Light weight construction
• Bi-directional sealing
• Sizes to suit application
• Lifting devices available i.e. lifting poles or
lifting beams
Stainless steel stop logs are designed for waste
water treatment plants, irrigation, hydraulic
works and hydro electric power plants.
They are made from grade 304, 316 or duplex
steel. The frames can be:
• Channel or wall mounted
• Bi-directional sealing
• Standard size range : 150 to 2000mm,
larger sizes available on request
• Lifting devices available i.e. lifting poles or
lifting beams dependent on size
