ET7200 Proportional Integral Electric Control Valve
The ET7200 series electric control valve is a combination of a 1000N force electric actuator and a DN20-DN65 control valve body. It is widely used in air conditioning, refrigeration, heating, and building automation systems to precisely regulate the medium flow in the system, thereby achieving control of temperature, humidity, pressure, and energy savings.
Product Features:
1. The actuator housing is made of die-cast aluminum (surface treated with sandblasting and painting), and the outer shell is made of ABS engineering plastic, making it compact and lightweight.
2. The actuator uses a reversible synchronous motor with overload limit switch protection. It includes a limit switch, and the actuator motor stops automatically.
3. Operating voltage: AC24V±10% 50/60Hz (customizable to AC220V).
4. Control signal: On/Off / Floating point signal / On/Off with passive signal feedback.
Analog: 0-10V/4-20mA feedback output, optional voltage 0-10V or current signal 4-20mA DC.

Installation Notes
Clean the pipeline before installing the control valve. Install a filter screen on the inlet side of the valve.
Leave sufficient space during installation to facilitate maintenance.
The medium flow direction in the valve body should match the arrow direction on the valve body.
If the installation position of the control valve is not specified in the design drawings, it is generally installed on the return water pipe.
Vertical installation is preferred. For special occasions, it can be installed inclined or horizontally, but support and fixation are required if the volume, weight, or vibration is excessive.
The valve flange and pipeline connection should be concentric to avoid shear force. Tighten the connection bolts naturally.
