Our company, set up in 2008, is located in the eastern suburb of Beijing. In the very beginning, we could only produce diaphragm check valves with only one specification. Now, we are able to manufacture the mini-type diaphragm check valves with all the five interface specifications of "1/8", "3/16", "1/4", "5/16" and "3/8". Besides, we have developed the spring check valves and the oil-way check valves, which are on continuous improvement. Apart from this, our company has spread to the manufacture of micro-diaphragm pumps and the non-touch liquid level switches.

We have built long-time business cooperative relationship with Bartels Company in Germany and promoted the application of micro-diaphragm pumps all over the world. The non-touch liquid level switches are developed to meet the customers' need. They are researched and developed by our own company. They are mainly used to protect the liquid level of mini-type plastic containers. The advantages are easy to install and low-cost.

We always insist on the spirit of "diligence, reality and creation during our development". We aim to set up our own brand of "Jiyue Plastic" and provide our customers with proper products and technique services.
