Globe valves

Plan and install in record time

Globe valves are used for flow shutoff, flow regulation or fluids mixing in the majority of HVAC applications. Siemens recommends globe valves especially for floor heating, zone control, heating groups, district heating and boiler plant applications.


Acvatix globe valves provide you with:                                                                      

  • Reliability rates and long service life, even in extreme temperature and high pressure environments
  • Fast installation 
  • Visible operating and position displays for easy troubleshooting during servicing
  • Simplified system modernization with backwards compatibility 
  • Siemens HVAC Lab product quality certification

Hydronics made easy

PICVs (pressure-independent combi valves) prevent oversupply and reciprocal hydronic interference, reducing energy consumption and operational costs. Additionally, PICV enabled precise temperature control improves the comfort and wellbeing of building users. Siemens recommends PICVs especially for radiators, chilled ceilings, VAV and fan coil units.


Acvatix product benefits:

  • Simple planning and implementation of energy-efficient HVAC systems
  • Flexible planning thanks to continuous volumetric flow ranges and large differential pressure ranges
  • Simplified dimensioning, presetting, hydronic balancing, and commissioning
  • Easier system extension with independent pressure control       
Control ball valves
Control ball valves

An excellent choice for your business

Designed for efficiency, with precise control and leak-free operations, control ball valves are used for continuous and precise control in closed circuits. Siemens recommends control ball valves especially for air handling units and the 6-port control ball valves for heated and chilled ceilings.


Acvatix benefits:

  • Simple handling for quick, error-free installation 
  • Highly efficient, with low torque and friction, and fine kvs graduation
  • Broad range of actuators and customer-specific adaptations
  • Flexible connection with internal and external thread screw fittings for the 6-port control ball valves
Magnetic valves

Solid conditions with accurate control

Magnetic valves are valves with a pre-installed magnetic actuator. They are used for the shutoff and mixing of fluids (water, water with antifreeze, heat transfer fluid etc.) and steam in nearly all HVAC applications. Magnetic valves are also ideal for applications with even the most stringent requirements, including industry-related areas such as engine test benches. Siemens recommends magnetic valves especially for domestic hot water and chiller plants.


Your benefits with Acvatix:

  • Energy efficiency 
  • Rapid, magnetic valve control in under two seconds
  • Precise drop-by-drop control, for high efficiency and stable control conditions
Rotary valves
Rotary valves

Close off and mix reliably

Rotary valves are primarily used in energy generation and distribution. Typical applications are if an additional boiler needs to be connected, or for the switching over of storage tank charging. Siemens recommends rotary valves especially for cooling towers.


Acvatix benefits:

  • Fast and simple valve-actuator coupling
  • Large dimensions for the highest volumetric flows
  • Visibility of operating status and position displays for easy service troubleshooting 
Refrigerant valves

Hermetically sealed for highest safety

The Acvatix range offers hermetically sealed mixing, diverting, and 2-port valves for refrigeration plants. They also include refrigerant valves for expansion, hot gas and suction throttle applications. All Acvatix refrigerant valves save energy in the refrigeration plant, for example through their accurate superheat control also in part load situations.


Your benefits with Acvatix:

  • Hermetically sealed refrigerant valves – also in IP65 design
  • Energy savings with accurate superheat control, fine stroke resolution and <1 second  positioning time 
  • Vibration-free operation
  • Safety feature for power failure 
  • Control of dynamic processes
  • Easy to install and service  
  • High degree of environmental compatibility

PICVs – pressure-independent combi valves

Why PICVs?

Simple: Pressure-independent combi valves (PICVs) make your daily work easier – planning, installation or commissioning – while also ensuring enhanced occupant comfort and low energy costs.  

PICVs combine the following into one valve body:

  • A control valve
  • A differential pressure controller that shields against pressure fluctuations in the hydronic network
  • A presetting scale for the desired maximum volumetric flow
  • Pressure measuring points for differential pressure measurement.

Properly equipped, PICVs prevent oversupply and reciprocal hydronic interference.
