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

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.

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.

Quality & Testing

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.

High quality penstock manufacturers based in Spain and are a member of

the AVK group of companies

SAFOX© PENSTOCKThe 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.

OBX 10/13 Revision 2SL-1

The Orbinox model SL Stop Log is designed for openchannel installations in waste treatment plants, irrigation,hydraulic works and hydro-electric power plants.The slide is formed by several logs that fit on top of eachother in the frame. By adding or removing logs, the SLmodel allows the user to control the flow in a channel.The sealing system is incorporated on both laterals andbottom area of each log, resulting in a substantiallywatertight seal. From sizes 150mm x 150mm to 2000mmx 2000mm, the SL model has a unique “lip” type sealdesign. The frame of the SL model is typically embedded inconcrete, but can also be designed to be wall mounted orface mounted in an existing channel.Orbinox can also design and manufacture the SL modelStop Log in larger dimensions and for higher serviceconditions while maintaining a low leakage rate. For moreinformation, please contact an Orbinox representative.

The standard SL model is manufactured in stainless steelwhich has a higher corrosion resistance in manyapplications which results in a higher life cycle with little orno maintenance. Other materials of construction areavailable upon request, such as AISI 904L, Duplexstainless, etc.
