Example:
1 VXP45.10-1 three-port valve
Valves, actuators and screwed fittings are packed separately.
Valves V…45.10-0.25 to V…45.25-6.3 are operated with SSB actuators (see data shee
CA1N4891.1E-P25 and CA1N4891.2E-P25) or SSC actuators. Valves V…P45.25-10,
V…45.32-16 and V…P45.40-25 are only operated with SSC actuators.
