Technology and Function

Product Features

Name: The multiport selector valve is an electric selector valve independently developed by RUNZE Fluid Control Equipment Co., Ltd., also known as electric rotary valve;
Control: The selector valve integrates motor control circuit. By receiving instructions from the host computer to control the operation of the stepper motor to make the rotor turn to the specified hole position to achieve the switching of the flow path. Serial communication protocol supports RS232/RS485/CAN bus.
Corrosion Resistance: This type of selector valve adopts sapphire valve core, which can be applied to various corrosive liquid. The valve head is made of PCTFE (polychlorotrifluoroethylene) and stainless steel 304, maintenance-free and the liquid is not in contact with the stainless steel.
Valve Core Structure: The valve core adopts a multi-directional self-adaptive plane fitting method, which can extend the service life of the product effectively. (This structure has been applied for utility patent, patent number: CN204852471U)
Motive Power: The rotation of the valve body adopts the imported NMB planetary gearbox motor as the power plant, which is extremely reliable.
Orientation: The valve hole is oriented by optocoupler of code disc, which can effectively solve the problem of inaccurate positioning after the gearbox is worn down.
Drive: The drive module adopts a low-power drive chip. It can effectively reduce the heat generated when the chip is running which affects performance.
Control Unit Interface: XH terminal with 2.54mm pitch.
Mechanical Interface: 1/4-28UNF female thread.
Usage: Widely used in the collection and distribution of fluid samples.
Application: Environmental testing devices, experimental analysis instruments, medical analyzers, chromatographic instruments, etc.

Note:
Before using the selector valve, please read the “Instruction Manual” carefully and follow the provisions in it.

Description of Control Code

Overview

The data transmission between the selector valve and the host device (computer, single-chip computer, PLC, etc.) adopts serial communication (eg. RS-232/RS-485/CAN bus) and the following describes the communication format. The communication adopts asynchronous serial communication. Commands and data frames use sum check, and the sum check is two bytes (2 bytes). Commands and data in communication are in hexadecimal, and parameters are stored in little- endian mode.
Communication interface: RS-232, RS-485, CAN bus;
Communication mode: two-way asynchronous, master-slave mode;
Baud rate: RS232, RS485: 9600bps, 19200bps, 38400bps, 57600bps, 115200bps
CAN: 100Kbps, 200Kbps, 500Kbps, 1Mbps
Data bit: 8 bit
Parity: no check
Response time: <1 second

Note: ⑴ The code B2 in the response command indicates the current running status of the motor. Only when B2=0x00, the motor is in normal operation, and other parameters are shown in the above table, corresponding to different abnormal status respectively. In principle, the motor should be send the 0X4A command to query the motor status at the end of the motor operation. Only when the B2 parameter in the response command is 00, other commands can be executed correctly.
Note:
The code parameters of all the above commands are set in little-endian mode. Low data is stored in the low bit of the address and high data is stored in the high bit of the address.
