Shuntopac® Dynamic – shunt units with built-in differential pressure regulation and dynamic balancing
TTM Shuntopac® Dynamic provides correct adjustment even in systems with varying differential pressures or where the differential pressure is unknown. Equipped with a multifunction valve (PICV, combi valve) with combined functions:
- Modulating control valve
- Differential pressure regulator
- Dynamic balancing valve
Functions
- The control function regulates the flow according to the current power requirement
- The differential pressure function takes care of pressure variations in the primary system and keeps the differential pressure constant over the control valve cone
- The adjustment function limits the flow to the set value.
Benefits
TTM Shuntopac® Dynamic provides correct regulation even in systems with varying differential pressure or when the differential pressure is unknown. However, see technical specifications for working area for each valve model and size. TTM Shuntopac® Dynamic comes from manufacturer with the primary side adjusted to the projected flow.
This means that when the shunt unit is installed, only the secondary side of the shunt unit needs to be adjusted and that the differential pressure on the primary side is within the working area need to be checked. All TTM Shuntopac® models can be delivered with Dynamic design.

Equipment
1. Multifunction valve (PICV, combi valve)
These valve types have the following built-in functions:
a) Control valve, seat valve type
b) Differential pressure regulator which maintains a constant differential pressure over the plug of the control valve
c) Dynamic adjuster valve (max. flow restrictor)
d) Actuator
2. Adjuster valve
1 x of any make and dimension for adjustment/control of the flow on the secondary side of the shunt. Fitted in a pipe with a conical coupling or flange. The TA STAD/F make is supplied as standard.
3. Pump
Any make and type with a “wet” or “dry” motor.
4. Test sockets
Test sockets are attached on each connection, allowing
adjustment of the shunt unit primary side.
5. Shut-off valves
3 x ball valves DN20 to DN50 with full bore and tall spindle neck, or 3 x butterfly valves DN65 to DN200, designed to function as end valves if the shunt unit is removed from the system. Fitted to the pipe kit using conical couplings or flanges.
6. Thermometers
Graduated 0-120 °C for heat and -40 – +40 °C for cooling.
7. Non-return valve
1 x made of brass/cast iron/stainless steel with spring-loadedplug. Mounted in a flange.
8. Draining device
Version with R1/2″ hose fitting at all low points.
9. Data plate
10. Flow chart
11. Mounting bracket for wall mount
Options
- Floor stand
- Flexfit pipe bends
