Electric three-way adjusting ball valve

1. structure characteristics and application scope

Two seat sealing electric three-way adjusting ball valve compact structure, good sealing performance. It can realize the switching of the medium flow direction in the pipeline. It is also possible to connect or close two channels perpendicular to each other.

Four-seat sealing electric three-way adjusting ball valve has beautiful appearance, compact and reasonable structure. The electric three-way adjusting ball valve can not only realize the switching of the medium flow direction, but also make the three channels communicate with each other. At the same time, it can also close any channel to make the other two The channel is connected, and the convergence or diversion of the medium in the pipeline is flexibly controlled.

Main technical indicators of 2. control module

1. Control precision: 0.1%~ 3.1% adjustable.

2. Accept control signal: 0 ~ 10mA.DC, 4 ~ 20mA.DC or 1~5V.DC

3. Key selection: 1. When the input signal is interrupted: "interrupt" mode (open, stop, close) 2. Positive and negative action selection 3. Control accuracy selection.

4. The fully open and fully closed position of the electric device is automatically positioned and calibrated, which is convenient and accurate.

5. According to the input signal and the position of the electric device, the intelligent step distance adjustment is automatically positioned, and the oscillation suppression accuracy is high.

6. Output electric device position signal: 4 ~ 20mA.DC corresponds to fully closed and fully open electric device.

3. implementing agency

Type: optional PSQ, 3810R, LKR angular stroke actuator. Explosion-proof type selected 3810 series.

Technical parameters and performance: please refer to the instructions of the corresponding actuator and valve positioner.
