Valves for thermostatic sensors

KOVM

KOVM is 3-way mixing valve which can, among others, be used for the water-side regulation of terminals in the form of “fan-coils” or as induction units. It can be combined with RAVK self-acting thermostatic actuator.

RAV

VFG / VFGS 2 / VFU

Valves for heating, district heating and cooling systems.

The valves can be used with following actuators:​​​​​​​
    - Thermostats (TR) AFT...;
  ​​​​​​​  - Safety Temperature Monitor (STM) STFW;
  ​​​​​​​  - Actuators AMV(E) 655, 658, 659.

VG / VGF

VG and VGF are pressure relieved 2-way normally open (NO) valves, designed to be combined with:

• AVT thermostatic actuators
  
• STM safety temperature monitors
  
• STL safety temperature limiters
  

• For domestic hot water (DHW) production: hot water tanks; storage charge systems; instantaneous domestic hot water production.
  
• In mixing loops and room heating systems as well.

VGS

VGS is pressure relieved 2-way normally open (NO) valves for steam, designed to be combined with:

• AVT Temperature actuators;
  
• STM Safety temperature monitors;
  
• STL Safety temperature limiters;
  
• AMV(E) 20 / AMV(E) 30 electrical actuators
  
• AMV(E) 23 / AMV(E) 33 electrical actuators with spring return function.
  
  

• DN 15-25
  
• k_VS 1.0-6.3 m³/h
  
• PN 25
  
• Temperature: Steam/circ. water/glycolic water up to 30 %: 2 … 200 °C
  
• Connections: Ext. thread (weld-on, thread and flange tailpieces)
  
• Flow and return mounting
  ​​​​​​​

VGU / VGUF

VGU and VGUF are pressure relieved 2-way normally closed (NC) valves, designed to be combined with:
- AVT Temperature actuators;
- AMV(E) 20 / AMV(E) 30 electrical actuators;
- AMV(E) 23 / AMV(E) 33 electrical actuators with spring return function.
​​​​​​​
In combination with AVT temperature actuators and AMV(E) electrical actuators, valves can be used primarily in cooling systems.

VMA

VMA is 2-way seated valve primarily for use in district heating systems.

It can be combined with:

• ABV thermohydraulic actuators and
  
• VMA DN 15 can additionally be combined with self-acting thermostatic actuators RAVI, RAVK and RAVV.
  ​​​​​​​
  ​​​​​​​

VMT

VMT is 2-way seated valve primarily for use in heating systems.

It can be combined with:
• ABV and ABNV* Thermohydraulic actuators
• RAVI, RAVK and RAVV self-acting thermostatic actuators
* ABNV can be combined with VMT-/8 valves only.

Main data:
• DN 15 - 25
• k_VS 1.5 - 8.0 m³/h
• PN 10
• Temperature: Circulation water / glycolic water up to 30%: 2 … 120 °C
• Connections: Ext. thread

VMV

VMV is 3-way seated mixing valve primarily use for flow temperature control.

It can be combined with:
• AMV(E) 10, 13 electrical actuator
• AMV 150 + AMV(E) 130/140 electrical actuator
• ABV thermohydraulic actuator (NC version only for DN15 and DN20).
• VMV DN 15 and DN 20 can additionally be combined with self-acting thermostatic actuators RAVK
