 Technology and Function

Product Features

1.  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;
2. 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.
3.  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.
4. 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)
5. Motive Power: The rotation of the valve body adopts the imported NMB planetary gearbox motor as the power plant, which is extremely reliable.
6. 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.
7. 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.
8.  Control Unit Interface: XH terminal with 2.54mm pitch.
9. Mechanical Interface: 1/4-28UNF female thread.
10. Usage: Widely used in the collection and distribution of fluid samples.
11. 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.
 Naming Rules
The model parameters are as follows:For example: slope type 6-port sapphire selector valve is named as QHF-SV06-X-T6-K1.2-S.
Product Specification
The SV-06 selector valve can be divided into 6-port, 8-port, 10-port, 12-port and 16-port according to the number of ports. The 6/8/10-port can be installed in place of other selector valves of RUNZE . The size of the mounting plate is shown in Figure 2-3-2 (unit: mm).Structure Dimensions (unit: mm)Technical Parameters

 Flow Configuration
Center port is the common port and the valve can switch to any specific port by rotor. Flow configuration is shown . Reset Status
Reset direction is counterclockwise (unchangeable). After reset, the rotor slot is between the port 1 and the port of the maximum number. At this time, the center port and other ports are disconnected, as shown . Port DefinitionPort diagram

 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

 Installation and Debugging

1. Cable connection (including power supply and communication line) (see Figure 8 above);
2.  Installation and debugging tools, see 《Instructions for Debugging Tools》for details.
