Description

The electric two-way valve complements central air conditioning fan coil units and includes a drive unit and valve body. A synchronous motor powers the drive unit, featuring a spring return and manual open lever function. The valve body has a piston-type structure. The electric valve works with a thermostat to control the motor, opening or closing the valve to manage water flow. This process regulates the air supply from the fan coil unit, allowing for automatic temperature adjustment.

Function

1. The electrically actuated two-way valve controls temperature based on load. In summer, it adjusts or closes water flow when the room temperature falls below the set value. The electric valve interlocks with the fan coil unit’s power supply. When the fan coil unit stops, the electric valve closes and stops the water supply.
2. The two-way valve serves as a critical control tool, allowing smaller units to support larger ones across different zones. When the main unit-terminal ratio is large, each terminal’s outlet pipe requires an electric valve. This ensures sufficient water flow, conserves energy, and prevents coil condensation in the air conditioning unit.

Installation Instructions

Install the electrically actuated two-way valve on the outlet pipe near the end of the valve. If all terminals have two-way valves, install a bypass valve on the main pipe (a differential pressure bypass is recommended). When installing the electrically actuated motorized two-way valve in the air conditioning unit, use the unit’s interlock function, especially if many two-way valves are used without a buffer water tank.
