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
• kVS 0.25 - 4.0 m3/h
• PN 16• Logarithmic flow characteristic
• Temperature: Circ. water / glycolic water up to 50%: 2 ... 120 °C
Features and benefits
- Reduced kVS on B port (VZ3 & VZ4 only)
- Linear bypass on 3 and 4 port valves
- Valves are supplied with screwed plastic cover for manual operation
- Connections: flat end or conex
