Weirless Radial diaphragm valvesBioprocessing valves thatminimise contamination risk andsave up to 80% maintenance timeFluidTechnologySolutions
ASEPCO: Dedicated to qualityEfficiency by designASEPCO was established over 20 years ago with a single mission:to make the world’s best valves for aseptic processing.Every aspect of an ASEPCO valve is designed to minimise contamination risk, reducemaintenance and lower lifetime cost.Since then, biotechnology andpharmaceutical professionals havecome to realise a well designed,precisely built valve saves time andmoney, and reduces risk. We’vegrown and today we manufacturethe aseptic processing industry’svalve of choice.When you entrust your processfluid to an ASEPCO valve, wetake that responsibility seriously.We ensure every aspect of ourprocess—from the raw material tofast, convenient delivery—meetsyour needs.Fully traceable materialsSaves you time and moneyValves are made from fullytraceable materials, regardlessof the type of alloy you chooseensuring they meet your localstandards and codes.Our valves are designed to saveyou time and money. Changing adiaphragm only takes seconds,making our valves simple toinspect, easy to clean, andeffortless to use.Long‑lasting surface finishEach valve is fully machined,electropolished and passivated asstandard; giving you a consistent,long‑lasting surface finish.ASEPCO valves are designed to minimise risk.Changing a diaphragm takes seconds, with no needfor special tools or training, and a simple Tri‑Clamp assembly makes inspection fast and easy. Everysurface material that touches your process fluid ismanufactured to comply with multiple global industrystandards, safeguarding you and your process.12ASEPCO in‑line valves are built aroundour radial diaphragm that forms twoseals in one. This Weirless Radialarchitecture virtually eliminates the riskof contamination by entrapment, andmakes cleaning fast and easy.Defined shoulder seal eliminates entrapmentfor easy cleaningIn‑line valve features a 180 degree install anglewith full drainability in multiple orientationsTank‑bottom valves with up to three portsfor CIP/SIP or flushing while closedSimple Tri‑Clamp assembly makesmaintenance 80% faster43Simple Tri‑Clamp assemblyUp to 80% faster maintenance34Strong and lightweightactuators12FlowWeirless Radial diaphragmtank valvesASEPCO tank valves are also builtaround our patented radial diaphragm.Valves can be welded truly flush tothe bottom of your tank with no needfor gaskets, bolts or seams.

Valves specific to your applicationWithin our two valve ranges (in‑line andtank) we offer up to five different valvestyles with a variety of configurationsand material choices. Our tank valverange covers the most common sizesfrom 0.5” through 4”, while our in‑linevalve range is made up of 0.5” to 2”sizes.Weirless Radial diaphragm tank valvesFully tested and traceableCompliant with ASME BPVC, ASME BPE, CRN and CE‑PEDSupplied with material test reportsEvery valve serialised and laser‑etched316L stainless steel dual certified to EN 1.4435 andASME SA479 (also available in other materials)Our tank valves are designedspecifically to meet the stringentrequirements of the bioprocessingindustry. We offer several optionsto help solve the most challengingapplications.It is easy to weld our valves trulyflush to the bottom of your tankwith our heavy‑duty, thick weldflange. There are no gaskets, boltsor seams.Can’t find what you need?Our experienced engineerswill develop a custom valveconfiguration to meet your specificprocessing needs.Weirless Radial diaphragm in-line valvesDesigned to accelerate and simplify change-over times, the weirless in-line valve serieshas been developed with time and cost savings in mind.In‑line valveComposed of a forged body,the in-line valve is designedto provide a less restrictive flowpath over traditional weir stylevalves. The weirless designalso eliminates the potentialof trapping material throughour innovative, industryleading shoulder seal design.Configured to suit with clamp‑end or weld‑endconnections, or a secondary valveComplete fluid isolationEasy to assemble and inspect: Eliminates sources ofcontamination and reduces cleaning timeClean, self‑draining designDefined shoulder seal ensures contamination-freeprocessingEvery surface material that touches yourprocess fluid is manufactured to comply withmultiple global industry standards, safeguardingyou and your process.4Process valveOur hydrodynamic designgives you clean, consistentsampling every time.
