1522/2-way Globe Control Valve• New generation with interchangeable trims,3 to 5 Kvs-value per connection portProcess Valves 2712Type 2712 can be combined with...Type 8630PositionerTopControlcontinuousType 1067PositionerSideControlThe 2712 system has been specifically engineeredfor reliable control in applications where controlaccuracy is paramount.The 2712 is made from an all stainless steel valvebody combined with Bürkert’s new generation universalpneumatic actuator.Each globe valve body can be fitted with three to fivesizes of trim sets. These parabolic trims provide a reliableand repeatable characteristic to vary the flow.The control cones are available in either stainlesssteel or with a durable Teflon seal for tight shut-off.When actuated by the 1067/8635 SideControls orthe 8630 TopControl it forms a unique control valvesystem which can be operated as either a simpleaccurate positioner or an autotune PID process controllerfor flow, temperature or pressure.• Flanged, weld end or threaded portconnections as standards• Excellent control characteristic• Ultra compact designType 8635Positioner SideControlTechnical dataOrifice DN 10-100MaterialsBodyActuatorSeal materialSeat leakage IEC 534-4/EN 1349Process media gases andliquids (vacuum version onrequest)Cast stainless steel 316L (conform to 1.4409)PA (polyamide) (PPS on request)St.st./St.st.
