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.

SAFOX Penstock The Safox* range of penstocks from AVK is the premium penstock offering, giving full sealing characteristics in a number of installation options. 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. *copyright Büsch Technology GmbH Weir Penstock The weir penstock is a versatile 3 or 4-sided sealing suitable for wall mounted applications. 3 or 4-sided frame design Suitable for wall mounting with a square or rectangular opening Standard size range : 150 to 2000mm, larger sizes available Fabricated stainless steel frame and slide, resilient rubber sealing with non-rising or rising spindle available Bi-directional sealing Designed according to DIN 19569-4 Leakage allowance lower than allowable in DIN 19569-4 (class 5) Replaceable seals Variety of actuation options are available i.e. Manual, electric, extension spindles, pedestals 4 PENSTOCK SOLUTIONS
