EX7-M21 Alco electrical control valves 800625 Emerson 25-230 kW

As today’s systems require improved energy efficiency, tighter temperature control, a wider range of operating conditions and incorporate new features like remote monitoring and diagnostics,

the application of electronically operated valves becomes mandatory.

Only these offer the controls performance necessary to meet these needs. Electrical control valves are actuators only.

For operation in a system they need sensors, valve drivers and controllers.
