Hello, I'm Xiaoyong, and I'm glad to bring you guys another new Keyto product sharing. What I wanna share today is the multi-channel rotary shear valve series product, which is self-developed by Keyto.
Rotary valves have different names in the market, such as rotary shear valve, distribution valve, switching valve, etc. They are commonly used in the working environment where laboratory analytical instruments, water quality testing instruments, medical instruments, etc., which require switching the direction of multiple fluids flow. According to the function, rotary valves can be categorized into selective rotary shear valves and sampling rotary shear valves. The selective rotary shear valve is the connection that one channel is connected to multiple channels, and the sampling rotary shear valve is the connection between two channels.
The rotary shear valve products are mainly used to switch the direction of multiple channels of fluid. For example, the rotary shear valve of one channel with multiple selections works with a central port public channel connecting the stator and rotor for switching between channels, achieving the fastest response times of less than 130ms for adjacent positions and less than 780ms for the furthest position. When we use rotary shear valves together with pump products, fluid handling methods such as one-inlet and multiple-outlet, multiple-inlet and one-outlet can be realized.
Keyto rocker solenoid can be categorized into long lifetime model and regular model according to the service life. For long lifetime models, medium materials in contact with the fluid include PCTFE valve head, ceramic stator, and sapphire rotor. For the regular model, the medium materials in contact with the fluid include PCTFE valve head, PEEK stator, PTFE rotor. Both the stator and rotor are corrosion-resistant and wear-resistant. If you have any special reagent tolerance requirements, please feel free to contact us. Keyto supports customized material.
Keyto multi-channel rotary solenoid valve adopts advanced machining technology, strict inspection methods and a unique sealing solution to ensure the reliability and long service life of the product. For long lifetime model, the service life can reach more than 1,000,000 cycles when using saturated NACL solution as the medium, the operating withstand pressure is higher than 0.7 mpa.
For regular models, the service life can reach more than 200,000 cycles when using saturated NACL solution as the medium, and more than 500,000 cycles when using pure water as the medium, the operating withstand pressure is higher than 0.3 mpa.
The multi-channel rotary shear valve is integrated with the software drive controller independently researched and developed by Keyto, which controls the rotation of the step-motor by receiving the command from the host computer, and the step-motor drives the rotor to rotate to achieve the fluid path switching. Three communication protocols are available: RS232/RS485/CAN bus.
Keyto multi-channel rotary valve provides 6 channels, 8 channels, 10 channels, 12 channels, 16 channels, 24 channels and other different specifications of the channel for your choice, details can be checked through our official WeChat public account: keyto垦拓, or online customer service or telephone 0755-29516669. Expecting your visit! That's all for today's keyto product sharing! See you next time!
This is the first one.
