Large flow total control valve: Division I developed patented product, patent number: 201 220 379 865 Division I is the first big change for the heat flow thermostatic valve were developed and patented by the manufacturers, began to promote in 2012 and after a test the heating season, and has been widely praised. The development of the series now includes two sizes DN20 and DN25, body material Seiko produced using copper 59-1, 57-1 high copper content of the material than the market widely used, low lead content, good mechanical properties, resistance freezing tolerance has improved significantly, environmental protection and good; EPDM rubber seal material and comply with stringent European standards WRC; our sealing pad structure using more complex riveting installation, and after upgrades to improve safety and reliability never fall off; the design of rigorous science, our high flow valve with electric actuator with the stem, use ingenious structure, eliminate dependence on workers installing accuracy, according to a certain torque tighten the valve stem installation dimensions All the important factors to within a tolerance of ± 0.15mm, long-term stability of the product to provide a guarantee, the market now appears to produce many products can not be completely turned off by lax or after a period of time, among them the stem; we Each valve is fine. Which, DN25 kv value of 4.3; DN20 kv value of 3.8, and fully meet the requirements of high-volume low-pressure heating system; the same time, low pressure drop characteristics of the valve, it is the best partner with the hot table. Electric actuators: We developed an electric actuator, crafted, every part, every detail in the design process as well as all the intentions to control, core power components using the original French imports, low power consumption, stable performance, overall smooth operation, long life. In the structural design, we used a special institution and shape, ensuring a good action premise, give full consideration to the heat problem, bulb contacts, power lines and other sophisticated design and reliable, making 304 stainless steel springs, which are for improving life made effective protection, in addition, we have a unique sealed internal instigation, capable of displaying the status of the open valve off valve, there is 24V normally open, normally closed and 220V normally open, normally closed four specifications. Our research and development, manufacturing of electric actuators has several advantages: 1, using machinery imported from France bulb heating devices, to prevent the heat unstable, leaking, travel unstable, short life and so many other issues; 2, a unique smooth The exterior design is different from the common variety of mass market design image, while increasing the mirror triangle window actuator movement by the red line in the window visible; 3, advanced design tools + a wealth of experience in the design, combined with high-precision, high demand High levels of mold manufacturing system, the appropriate choice of resin formulations, to create excellent quality products inside and outside the structure and aesthetic appearance; 4, by means of a variety of experiments repeated testing and updating, making the implementation of more advanced structure is more reasonable and reliable ; 5, using high-quality standards in accordance with VDE power cord, to enhance the overall safety and reliability of the product and a good visual appearance; before being packaged 6, a series of tests for each product manufactured to stringent quality control measure ensure first-class product quality.
