These three port mixing valves are used for modulating
control of hot or chilled water in heating, ventilation and air
conditioning systems and can be operated by electric linear
actuators as ML6420/6425, ML7420/7425, M6421/7421 or
by pneumatic actuators MP953. FEATURES
• Cast iron body with flanged end connections
• Metal to metal seating for long life span
• Self adjusting packing
• Accurate positioning to ensure state of the art
temperature control
• Direct coupled electric and pneumatic actuators for
easy mounting
• Constant total flow throughout full plug travel
