Introduction

The electric three-way valve is a machine used for fluid control in industries and industrial sectors such as air conditioning, thermal ventilation, and heat treatment plants.

Electric three-way valve - Yibiao Valve, VB3000 and VB7000 series electric three-way valves are used for fluid control in air conditioning, thermal ventilation, and heat treatment plants.

Used in civil systems such as building materials, metallurgy, light industry, grain, air conditioning, heating, ventilation, as well as chemical, petroleum metallurgy, and fluid automatic control.

Working Principle:

This valve mainly consists of a valve body, valve shaft, valve plate, crank mechanism, electric actuator, etc. During operation, the linear reciprocating motion of the electric actuator drives the valve shaft and valve plate through the crank to swing at a certain angle, thereby controlling the flow direction of materials and achieving the purpose of distributing materials.

Product Features

1. The actuator uses cast aluminum brackets and a plastic housing, making it compact and lightweight.

2. Equipped with a permanent magnet synchronous motor and a hysteresis clutch mechanism, ensuring reliable self-protection.

3. Compatible with various control signals: incremental (floating point), voltage (0~10V), current (4~20mA).

4. Features 0~10V or 4~20mA feedback signals (optional).

5. The transmission gears are made of metal, significantly extending the drive's service life.

6. Low power consumption, high output force, and low noise.

7. The valve body is available in various materials such as cast copper, cast iron, and ductile iron to suit different working media and temperature requirements.

8. The valve body offers two connection types: threaded and flanged, ensuring easy installation.

9. Valve body structure types include: three-way confluence valve and three-way diversion valve.
