Acvatix – valves and 

actuators for room and 

zone applications

Acvatix – valves and actuators 

for room and zone applications 

TEVA (Terminal Equipment Valves and Actuators) is the 

comprehensive range of valves and actuators from Siemens 

covering all major HVAC applications in rooms and zones 

and satisfying all customer requirements. 

Thanks to the clear and application-related 

structure, the right 

combination of valve and actuator 

can be quickly and straightforwardly 

selected for any type of 

application – be it for fan coil units, 

chilled ceilings, or general zone 

or radiator applications. The valves 

and actuators offer long service 

life, are of very high quality and 

excel in rugged design, low-noise 

operation, and performance. Owing 

to an optimum match of valves, 

actuators and controllers, TEVA 

products make a major contribution 

to energy efficiency. As a result, 

energy and costs are saved. 

This way, you select products that 

offer you the highest levels of 

efficiency and reliability – from 

installation to maintenance. This 

is made possible not only by tools 

specifically developed by Siemens 

for sizing, calculation and project 

handling, but also by worldwide 

on-site support in more than 50 

countries. 

Highlights 

■ Comprehensive range of valves 

and actuators for all major HVAC 

room and zone applications 

■ Straightforward, fast and 

secure selection of the right 

valve actuator combination 

■ Highest levels of efficiency and 

reliability thanks to product 

range that offers longevity, 

quality and performance 

■ Significant energy and cost 

savings, reduced effort 

■ Excellent support owing to tools 

and worldwide presence of 

Siemens

HVAC Integrated Tool – 

comprehensive support 

The HVAC Integrated Tool (HIT) developed by Siemens is a software 

package that enables you to reliably plan and engineer 

heating, ventilation, air conditioning and refrigeration plants – 

more straightforwardly and faster. 

HIT simplifies the selection of 

products: The tool enables you to 

directly access the complete HVAC 

portfolio marketed by Siemens, 

which includes more than 2,500 

products – valves, actuators, 

controllers, sensors, thermostats 

or variable speed drives. 

To allow you to plan projects 

straightforwardly and quickly, 

HIT also offers you … 

… more than 300 standard 

applications, 

… integrated product selection 

modules for demand-oriented 

selection of products (e.g. in 

connection with sizing), 

… automatic generation of your
