1 Datasheet No.: TPF-B-0 TPF-Series Flow Limiter Valve Body Material:Ductile iron QT450-0 Caliber:DN50...DN250 Standard of flange connection in accordance with ISO Characteristics Valve Stroke: Max 20/40mm Temperature Range: -0~50 The Max. Shut-off DP: 8Bar. The Flow limiter shall consist of two functional control elements. 2. The first element serves as an electrically actuated control valve, capable of responding to a control signal from a controller that is not part of the flow limiter. 3. The second element is based on the first element and serves to sense and regulate a preset flow differential pressure across the control valve. 4. Closing off differential pressure of actuator connected with flow limiter shouldn't be less than the pump head. 5. The flow limiter shall be precalibrated to a maximum flow rate as given by a customer. 6. Balancing cavity of the flow limiter adopts built-in connecting pipe. It has more compact structure and can avoid damages during installation compared with external connecting pipe. 7. Higher in cut-off differential pressure while lower in the possibility of leakage. 8. Valve body is made of ductile iron material, with anticorrosion treatment on the surface, delicate in apperance. 9.The standard features of actuator are with manual function and power switch. 0. Control valve adopts straight travel proportional actuator, it has higher control accuracy. Equal linear flow character can be achieved ideally.. Maximum flow can be regulated by aperture potentiometer on PCB or by external KVS regulator.

3 Differential Pressure Flow Curve Aperture Flow Curve flow Relationship of Aperture and Flow aperture q=r (L-) "q" represents percentage of flow, namely ratio of current flow and max. flow. L represents percentage of opening, namely ratio of current opening and whole stroke. R represents adjustable ratio, namely ratio of max. flow and min. flow with control range. (we can produce the valve with 20 adjustable ratio) Note:. This formula is the relationship of valve opening and flow with constant differential pressure.

4 Mounting Orientation Medium is chilled/hot water Maintenance Downward installation is forbidden When doing service work on the actuator:. Close the pump and turn off the power supply. 2. Close the shut-off valve, exhaust water in the pipe to reduce the pressure inside pipes.make water pipe(hot water) cool down naturally. 3. Dismantle electric wires from wiring terminals. Remark: Before debugging valve again, install actuator correctly.! Notice:When we do the pipe pressure testing and flushing, the valve body should be in a state of full open.this operation can not only protect the internal parts of valve body, but also prevent pipe from blocking.
