Zone Valves

Zone Valves support flow measurement, switching, control, or installation work in liquid, gas, air, water, and process systems. Products in this category span three-way electric zone valves, bidirectional HVAC zone valves, hot and cold water control valves, 24 and 120 Vac actuator options, spring return models, and externally accessible manual override features.

Applications include heating and cooling zones, fan coil units, hydronic loops, building automation, chilled water, hot water, and HVAC equipment where each zone requires electrical flow control. Products represented in the source data include Dwyer Instruments.

Applications include:

• Control hot or cold water flow by zone
• Use two-way or three-way valve arrangements
• Apply spring return or bidirectional motor operation
• Connect valves to 24 or 120 Vac control circuits
• Use manual override during setup or service
