Valves for terminal & zone

VZ 2/ VZ 3/ VZ 4

VZ valves provide a high quality, cost effective solution for the control of hot and/or chilled water for fan coil units, small reheaters, and recoolers in temperature control systems.
The valves are used in combination with AMV(E) 130/140, AMV(E) 130H/140H and AMV(E) 13 SU actuators.

Main data:

• DN 15, 20
  
• k_VS 0.25 - 4.0 m^₃/h
  
• PN 16
  
• Logarithmic flow characteristic
  
• Temperature: Circ. water / glycolic water up to 50%: 2 ... 120 °C
  

VZL 2/ VZL 3/ VZL 4

VZL valves provide a high quality, cost effective solution for the control of hot and/or chilled water for fan coil units, small reheaters, and recoolers in temperature control systems.

The valves are used in combination with:
    - AMV(E) 130(H)/140(H) ABNM A5 with extension plug;
  ​​​​​​​  ​​​​​​​- AMV(E) 13 (SU) and TWA-ZL actuators.

Note: TWA-ZL thermal actuator does not close port B. In case that stem extension plug is not used together with AMV(E) 130(H)/140(H) dead zone in valve close position will occur.
