产品型号: QKL-B1T/QKL-B3-1/QKL-B3-1A

此为一个闭回路设计,由两个电磁阀、压力传感器以及电子回路控制所组成。

根据接收到的模拟讯号输入,由一端电磁阀用来控制进气量,与另一端电磁阀来控制排气量,透过压力传感器测量得到并回馈于电子回路控制,以达到精确的压力比例控制,该比例阀适合针对随时需要精准调控压力变化,与监控压力值的产业。

比例阀输入信号提供了0-10VDC(电压) 与 4-20mA(电流) 及 RS485 ModBus 通讯选择。监控输出则有 1-5V、0-10V及4-20mA 的选择。B1T、B3-1、B3-1A 系列为内部压力传感器 B2T、B3-2 系列为搭配外部压力传感器 (※适合用于远程造成压差的环境条件下)压力比例阀,除了会自行调控达到恒压以外,还能回馈参数到机台上做监控,排除压力值不准或压差造成的震荡问题。

本产品皆符合CE认证、SGS、RoHS、ISO13485 等认证。

Product Precautions

Installation
The valve can be mounted in any position. For very low pressure control, works best when mounted upright.
And Ensure a minimum closed end volume of 40c.c. to allow proper functioning.

※Preparation Before Piping
Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove chips, cutting oil and other debris from inside the pipe.
Wrapping of Sealant Tape
When screwing together pipes and fittings, etc., be certain that chips from the pipe threads and sealing material do not get inside the piping. When sealant tape is used, leave 1.5 to 2 thread ridges exposed at the end of the threads.

Operating Environment

  1. Do not operate in locations having an atmosphere of corrosive gases, chemicals, sea water, or where there will be contact with the same.
  2. In locations where the body is exposed to water, steam, dust, etc., there is a possibility that moisture or dust could enter the body through the EXH port, solenoid valve EXH port and/or built-in regulator EXH port, thereby causing problems.
  3. In locations which receive direct sunlight, provide a protective cover etc.
  4. In locations near heat sources, block off any radiated heat.
  5. Employ suitable protective measures in locations where there is contact with water droplets, oil or welding spatter, etc.

Air Supply

  1. Compressed air, nitrogen, oxygen or argon can be used as a fluid.
  2. Do not use compressed air which includes chemicals, synthetic oils containing organic solvents, salt, or corrosive gases, etc., as this can cause damage or malfunction.
  3. If oxygen is used as the fluid, it can lead to serious and unforeseen risks. However, it is possible to manage and control the risk of hazards and economic loss. In order to use the product safely, it should only be handled by personnel with appropriate knowledge, with support from a suitably qualified specialist.
  4. Oxygen gas increases the susceptibility of substances to burning; Oxygen gas can be ignited by frictional heat and static electricity. If oxygen is ignited, the metal and seal materials burn. Therefore, flush the piping thoroughly and mount a suitable filter to prevent foreign matter such as metal powder and dust from entering the product.
  5. Take safety measures by installing safety devices (e.g. a circuit that stops the supply of oxygen gas) to prevent fire and explosion in the event of failure, taking flameproof safety standards into consideration.
  6. Since there are some exhaust ports on the product, connect the piping in order to exhaust oxygen. Do not block the exhaust port.
