for chilled and low-temperature hot water systems or
for systems with media containing mineral oils (MX..461..P)
• Fast positioning time (< 2 s), high-resolution stroke (1 : 1000), high rangeability
• Equal-percentage or linear valve characteristic (user-selected)
• Operating voltage AC 24 V
• Switch-selected control signal DC 0/2...10 V or DC 4...20 mA
• DC 0…20 V phase cut control signal with SEZ91.6 external interface
• Indication of operating state, position feedback and manual control
• Wear-free inductive stroke measurement
• Fail-safe feature: A → AB closed when de-energized
• Low friction, robust, no maintenance required
Use
The control valves are mixing or throughport valves with the ready fitted magnetic
actuator for position control and position feedback. The short positioning time, high
resolution and high rangeability make these valves ideal for modulating
• control of chilled and low-temperature hot water systems
• control or dosing control of fluids containing mineral oil (SAE05...SAE50), mineral-oil-
based diesel fuels, heat transfer oils
in closed circuits.
