144Zero Deadleg T-Valve, ManuallyOperated, Stainless Steel Block MaterialProcess Valves 3234Type 3234 can be combined with...Type 8034Flow meterThe Burkert Zero Deadleg T Valve system is designedfor control of ultra pure, sterile, aggressive or abrasivefluids. Enables especially optimal sampling, draining ordiverting of critical process fluids. The valve body ismachined from a single piece of block material(monoblock – no weld seam).The high quality diaphragms separate hermeticallycritical fluids from the actuator.The manual actuator in PPS or stainless steel canbe sterilized.Validation / certification•Certification of Conformity for Raw MaterialEN-ISO 10204 3.1.B•Attestation of compliance with the orderEN-ISO 10204 2.1•Test report EN-ISO 10204 2.2•3A Certification•Certification of Conformity for Pickling andElectropolishing Processes•Certification of Conformity for the SurfaceQuality DIN4762-DIN4768-ISO/4287/1•Certification of Conformity for the 100% Weldinspection or Endoscopy RCCM RSEM ASME•FDA CFR No. 21 177.2600 Certification•Test Certification and Conformity Certificationfor the Final Assembly of Diaphragm Valves•ISO 9001 CertificationMulti-Port Block Type 3233/2031Tandem valve• Fully integrated in Burkert’sProcess Control Systems• Zero dead volume• Monoblock – no welds• Quality certifications /Technical dataBody materials1) Internal Ra < 0.1 µm/4 µInch/500 Grit: on request• Monoblock stainless steel• 316 L/1.4435/BN2Fe < 0.5%/C≤ 0.03%Actuator materialsActuator and bonnet PPS, stainless steel 1.4581Seal materialMediaViscositySurface qualitiesEPDM, PTFE/EPDMNeutral gases and liquids, high purity, sterile, aggressiveor abrasiveUp to viscous(average roughness)Internal mechanical polished Ra ≤ 0.5 µm (20 µInch or 240 grit)Internal electro polished Ra ≤ 0.4 µm (16 µInch or 280 grit)Internal mirror finish 1) Ra ≤ 0.25 µm (10 µInch or 330 grit)TemperaturesMediaAmbient-10°C to +130°C (14 to 266 °F) (short +150°C) (302 °F)+5°C to +140°C (41 to 284 °F)Port connectionsWeld end • EN ISO 1127/ISO 4200• DIN 11850 Series 0 to 3• ASME BPE• SMS 3008• BS 4825(various other Weld end, Tri-Clamp® andSterile threaded end connections are available,please consult for advice)InstallationOption(on request, not for DN 8/10)As requiredLocking functionSubject to modifications
