Product Description
1 Product Overview
31XX series multi-channel rotary valve is a product independently developed by Keyto, the main function is to achieve multi-channel switching. This series of rotary valve has a variety of model selection. Moreover, this series of rotary valves can withstand different reagents under different working conditions, and the operating life can reach more than 1 million times.
1.1 31XX Series Multi-Channel Rotary Valve Characteristic
This rotary valve is integrated with a drive controller, which controls the operation of the stepper motor by receiving instructions from the host computer. So as to realize the fluid channel switch. There are three kinds of serial port protocol: RS232/RS485/CAN bus.
The rotary valve adopts sapphire spool, which can be applied to all kinds of corrosive liquids. The valve head is processed by PCTFE (polytrifluoroethylene), which is maintension-free.
Spool rotor rotation depends on the planetary reducer motor as the power device, high reliability.
Advanced zirconia ceramic processing technology, strict inspection procedures, unique sealing scheme, to ensure that the service life of the valve can reach more than 1 million times, without maintenance and care.
Contact with liquid medium parts of the material of good chemical resistance. Various materials can be selected to ensure the compatibility of chemical media.
1.2 Word Definition
--When measured, the flow rate of the medium, unit gal/min;
--Specifies the density of the water medium at 60°F,;
--Pressure difference between front and rear of element under test;
,--When measured, the density of the medium and the pressure difference before and after the front element.
Converted to the domestic general dimension, then:
Cv=0.03, which means that the flow rate of the component is 5ml/s under the condition of 25ºC and 50KPa.
