Honeywell V5050A, V5050B DATASHEET
V5050A,B
FLANGED LINEAR VALVE PN16 AND PN25/40
SPECIFICATION DATA
GENERAL
These three-port mixing valves are used for modulating
control of hot/chilled water or steam in heating, ventilation,
and air conditioning systems and can be operated by electric
linear actuators ML6420/ML6425, ML7420/ML7425, and
ML6421/ML7421 or by pneumatic actuator MP953.
FEATURES
• Cast iron body with flanged end connections
• Low seat leakage rate
• Metal-to-metal seating for long life span
• Self-adjusting packing
• Accurate positioning to ensure state-of-the-art
temperature control
• Easy mounting of direct-coupled electric and
pneumatic actuators
• Constant total flow throughout entire plug travel
