THE WEDGE IS THEHEART OF A GATE VALVE124AVK fixed, integral wedgenut sealed with EPDMrubber prevents corrosion.Unique features and benefits of the AVKwedge Fixed, integral wedge nut sealed withrubber prevents corrosion (1).Double bonding vulcanization processensures maximum adhesion of the rubber.Guide rails with integrated wedge shoesensure low friction and smooth operation(2).Rubber vulcanized to the core with min.1.5mm on all pressure bearing surfacesand 4mm on all sealing surfaces givesoptimum corrosion protection.Large rubber volume in the sealing areaprovides optimum sealing (3).Large plain and conical stem hole (4)prevents stagnant water and accumulationof impurities.AVK’s rubber compound features anoutstanding compression set value,resistance to water treatment chemicalsand ensures minimised biofilm formation.Fixed integral wedge nut preventscorrosionAVK’s wedge nut design is superior to thetraditional loose wedge nut design as itprevents vibration, corrosion, malfunction andwater hammer. The wedge nut is made ofdezincification resistant brass with lubricatingabilities.Integrated wedge shoes for smoothoperationThe fixed wedge nut, combined with the guiderails with integrated wedge shoes, secures asmooth operation of the valve and low operatingtorques. The wedge shoes protect the rubberagainst wear which otherwise would arisecaused by the friction during operation.DN450-600: Externalwedge shoes onreversed guide rails.DN40-400: Integratedwedge shoes ininternal guide rails.Efficient bonding is the key to durabilityThe wedge core is immersed in two differentbaths providing: A primer to prevent corrosion Bonding between rubber and ductile ironcoreWe offer the best rubber adhesion and corrosionprotection on the market.4 WATER & WASTE WATER TREATMENT3A thin layer of rubbermust remain afterthe peeling test.The double bondingprocess preventscreeping corrosion.
STATE-OF-THE-ARTRUBBER TECHNOLOGYAVK Gummi develops andmanufactures the rubbercompound for wedgesand gaskets using highlyadvanced technology.Impurities in the medium being carried willnot affect the rubber surface or the tightnessof the valve as they will be absorbed in therubber when the valve is in the closed position.When the valve is reopened the impurities willbe flushed away and the rubber will regain itsshape.Unlike most manufacturers of resilient seat gatevalves, AVK has it’s own in house manufacturerof rubber components, AVK GUMMI A/S. AVKGummi develops and manufactures the rubbercompound for wedges and gaskets usinghighly advanced technology. Data is collectedthroughout the entire manufacturing processwhich provides traceability of every individualingredient, each compound and the finalisedcomponents. AVK GUMMI carries out a numberof tests to ensure that the compression setvalues, the adhesion and the tensile strengthmeet the predefined requirements.No contamination of drinking waterExcellent ability to regain original shapeTHE COST OF GETTING IT WRONG.Competitor wedges - totally destroyed due to lack ofbonding and incorrect vulcanisation.The EPDM rubber composition is designed tominimise the formation of biofilm. The rubberwill therefore not provide a breeding ground forbacteria.High resistanceThe drinking water approved EPDM compoundsare resistant to ozone and water treatmentchemicals such as sodium hypochlorite solutionsand are taste, smell and colour neutral. The NBRrubber is resistant to oil and gas and holds anapproval according to EN 682.AVK GUMMI A/S has an extensive knowledgeof a rubber’s compression set (its ability toregain its original shape). Even after manyyears of service where the wedge rubber hasbeen compressed numerous times, the rubberwill regain its original shape and ensure a tightsealing.WATER & WASTE WATER TREATMENT 5
HIGH STRENGTH AND LOWOPERATING TORQUESStainless steel stems withwedge stop and rolledthreads.1 The wedge stop (1) provides a firm stopagainst the wedge nut when openingthe valve. This prevents the wedge fromcompressing the stem seals and damagingthe coating inside the bonnet prolongingthe durability of the valve. The stem threads (2) are rolled in a coldpressing process which maintains thesteel structure and therefore increases thestrength of the stem. This method resultsin smooth thread surfaces and bringsabout low operating torques and prolongeddurability.THE COST OF GETTING IT WRONG.Competitor’s spindles and wedge nut damaged due tolow quality materials and processes.Broken wedge nut2Damaged spindle threadand O-ring6 WATER & WASTE WATER TREATMENT
NO COMPROMISE ONLEAKAGE OR CORROSIONTriple safety stem sealingsystem1.2.3.4.5.1An NBR wiper ring protects againstimpurities from the outside.Two EPDM O-rings in a polyamide bearingprovide tightness around the stem.The full circle thrust collar of dezincificationresistant brass provides a low free runningtorque.An O-ring is the main seal to the flow.Hot melt seal.23Secure assembly of valve body and bonnet4A bonnet gasket fits into a recess between thevalve body and the bonnet, which prevents itfrom being blown out in the event of a pressuresurge. The bonnet bolts are encircled by thebonnet gasket, countersunk in the bonnet andfinally sealed with hot melt to prevent corrosion.5100% pressure testEvery single valve is pressure tested accordingto BS EN 1074-1& 2 and EN 12266 beforeleaving the factory.The epoxy layer thickness must bemin. 250μ on all surfacesThe impact resistance is testedwith a steel cylinderAVK gate valves have as standard internaland external epoxy coating in line with WIS4-52-01. The epoxy powder coating can beapplied either manually or robotically usingthe latest, process efficient, state-of-the-artequipment.Thorough control of the coatingWe control each batch of epoxy coated components to ensure a minimumthickness of 250μ. The impact resistance of the coating is tested by droppinga steel cylinder on the coating surface through a one meter long tube. Thecuring of the epoxy coating is checked in an adhesive disbondment (v cut)test. The coating of all internal surfaces are 100% holiday free tested toensure that there are no pin hole cavities exposing raw material.Each valve is 100% holiday testedWATER & WASTE WATER TREATMENT 7
