2 IMI TA / Control valves / KTM 512 Union threads/ansi flanges KTM 512 Union threads/ansi flanges High-performing and compact, these pressure-independent control valves for variable flow heating and cooling systems are particularly effective in situations requiring high temperatures and/or pressure drops. They are also suitable for use on the secondary side in district heating and comfort cooling systems. Rust protection is assured due to the electrophoretically painted ductile iron body, while the plug delivers valve characteristic, suitable for modulating control. Key features > > Inline design Inline flow allows high pressure drops without noise. > > Adjustable flow Ensures the design flow. > > Adapters For use with most available actuators. Technical description Application: Heating and cooling systems. Functions: Differential pressure control over the builtin control valve and flow control. Dimensions: DN Pressure class: DN 15-50: PN 25 DN : Class 150 Differential pressure (ΔpV: Max. differential pressure: 1600 kpa = 16 bar (ΔH max Min. differential pressure: Low flow (: 24 kpa (ΔH min Normal flow (: 40 kpa (ΔH min High flow (: 80 kpa (ΔH min (Valid for max. position, fully open. Other positions will require lower differential pressure, check with the software HySelect. Temperature: Max. working temperature: - with measuring points: 120 C - without measuring points: 150 C Min. working temperature: -10 C Media: Water or neutral fluids, water-glycol mixtures. Material: Valve body: Ductile iron EN-GJS-400 Diaphragms and gaskets: EPDM Valve plug: EPDM/Stainless steel Surface treatment: Electrophoretic painting. Marking: IMI TA, DN, PN, Kvs, material and flow direction arrow. Connection: DN 15-50: Male threads according to ISO 228. (Separate connections with ANSI flanges and UNC threads. DN : Flanges according to ASME/ANSI B16.42 Class 150. Max. lift of the control valve: DN 15-50: 10 mm DN : 20 mm Actuators: DN 15-50: TA-Slider 500 DN : TA-Slider 750 DN : TA-Slider 1250 For more details on actuators, see separate technical leaflets. KTM 512 can be equipped with adapters for the most common actuators - see Adapters for actuators. The max. lift of the actuator must be checked. In the case of a shorter lift the maximum achieved flow will be decreased. Consult your local sales office for details. 2

3 Operating function DN The throttle (2 for flow adjustment, the control valve (9 and the diaphragm operated inline the differential pressure controller (6 are built in series in a common valve body. Pressure upstream of the throttle acts through an internal impulse pipe (V+ to the inlet side of the diaphragm (8. Pressure downstream the control valve acts to the outlet side of the diaphragm together with a spring force. The differential pressure controller pressure relieves the control valve, and at the same time limits the flow to the preset value. As the control valve is pressure relieved, it is possible to use low force actuators. V Fixing nut 2. Throttle 3. Holes for plombing (throttle 4. Holes for plombing (valve body 5. Venting screws 6.

Control valve DN The control valve (8 and the diaphragm operated inline differential pressure controller (4 are built in series in a common valve body.

Pressure downstream of the control valve acts to the outlet side of the diaphragm together with a spring force. The differential pressure controller pressure relieves the control valve, and at the same time limits the flow to the preset value. As the control valve is equipped with lift limitation device, stepless adjustment of maximum flow is possible. As the control valve is pressure relieved, it is possible to use low force actuators. 1 V Venting screws 2. Diaphragm 3. Spring 4. Inline differential pressure controller 5. Valve body 6.

4 IMI TA / Control valves / KTM 512 Union threads/ansi flanges Sizing The valve is capable of achieving a maximum flow according to the product tables. Min. differential pressure: Low flow (: 24 kpa (ΔH min Normal flow (: 40 kpa (ΔH min High flow (: 80 kpa (ΔH min (Valid for max. position, fully open. Other positions will require lower differential pressure, check with the software HySelect. Installation Install the valve in the return pipe, downstream the consumer, or in the inlet pipe, upstream the consumer. Flow direction is shown by the arrow on the valve body. Install the valve so that venting is possible and the flow adjustment scale is visible. Check allowed positions of the actuator. Installation of a strainer upstream of the valve is recommended. When filling, vent the body by using the venting screws. Application example Normal pipe fittings Try to avoid mounting taps and pumps immediately before the valve. Installation recommendation for accurate measurement due to distortion of fully developed turbulent flow profile. KTM 512 4

5 Setting DN Release the fixing nut (1. Turn the flow setting screw (2 clockwise to the position of 0,0 turns. Turn the flow setting screw anticlockwise corresponding to the number of turns on the flow chart. Tighten the fixing nut. The flow setting can be sealed by using the holes (3a and 3b on the flow setting screw and the valve body. DN Release the fixing nut (7. Turn the flow setting screw (6 clockwise to the position of 0,0 turns. Turn the flow setting screw anticlockwise corresponding to the number of turns on the flow chart. Tighten the fixing nut. 7 6 Detailed instructions are delivered with the valves. Table - Example: Valid table is delivered with each valve.

6 IMI TA / Control valves / KTM 512 Union threads/ansi flanges Actuator recommendation at varying inlet pressures The minimum actuator force required to operate the KTM 512 valves is dependent upon the maximum inlet pressure of the system. The following table shows the actuator recommendations from IMI Hydronic Engineering at varying inlet pressures. For other inlet pressures, the graph (Fig. 1 should be used to establish the minimum actuator force required.
