MVF461H 2" 2-Way Magnetic Control Valve, 35.1 Cv

Control valves with magnetic actuators, for modulating control of hot water, high temperature hot water, and steam.

The MVF461H Series valves are through-port or mixing valves with magnetic actuators. The actuator is equipped with an electronics module for positioning control and position feedback. If the power is off, the valve control path A to AB is closed. The short positioning time, high resolution and high rangeability make these valves ideal for proportional control of district heating stations, and heating applications using high temperature hot water and steam.

Features:

• Fast positioning time (< 2 seconds)
• Selectable valve characteristic: Equal percentage or linear
• Selectable standard interface: 0/2 to 10 Vdc or 0/4 to 20 mA
• High resolution (>1:1000)
• High rangeability
• Wear-free inductive stroke measurement
• Spring return A to AB closed when de-energized
• Positioning control and position feedback signal
• Low-friction, heavy-duty and maintenance-free
• Phase-cut signal input for Staefa controllers
