product description: four-way valves used in oil, natural gas, coal, mining, refining, processing, pipeline transport system; Chemical products, medicine and food production; Water and electricity, thermal and nuclear power production system; Urban and industrial water supply and drainage, heat supply, gas supply system; The drainage irrigation system; Widely used in gold production systems, the production and construction, national defense construction and people's life is closely related to the important mechanical products. Ball valve closed in all kinds of pipe system, in order to cut off or open medium flow, so that in accordance with the scheduled program will medium to each of the specified point. The performance parameters: 1. Pressure of work: 1. 6Mpa- 42. 0Mpa。 2. Working temperature: - 196≤650℃。 3. Drive mode: manual, worm, pneumatic and electric. 4. Connection mode: internal thread, external thread, flange, welding, butt welding, socket welding, clamping sleeve, fixture. 5. Manufacturing standard: national standard GB, JB, HG, American standard API, ANSI, British standard BS, JIS, JPI, etc. 6 valve body material: copper, cast iron, cast steel, carbon steel, WCB, WC6, WC9, 20 #, # 25, forged steel, A 105, F11, making, stainless steel, 304 L, 316 L, chrome molybdenum steel, low temperature steel, titanium alloy steel, etc. How it works: ball valve evolved from cock. The movable part, as a sphere, using the ball around the stem axis rotate for 90 o, achieve the goal of opening and closing. Ball valve is mainly used for cutting, distribution, and change the flow direction of the medium inside the pipeline. Design for v-shaped opening - ball also has a good flow regulating function. Ball valve has simple structure, good sealing, small volume, light weight, material consumption, small installation size, small driving torque is small, simple operation, convenient opening and closing. Ball valve is one of the fast developing varieties of valves for nearly a decade. Especially in the United States, Japan, Germany, France, Italy,, Britain and other western developed countries, the ball valve has a very wide range of use, increasing varieties and quantity, and with high temperature and high pressure, big, high sealing, long life, good regulation performance, and the multi-function direction of check valve, its reliability and other performance index has reached the high level, and parts replaced gate valve, cut-off valve, throttle valve. With the progress of ball valve technology, in a short period of time in the foreseeable, ball valve in oil and gas pipelines, oil cracking device and get more and more widely used in industry. In addition, in other industries, in large and medium size, medium and low pressure areas, ball valve will also become one of the dominant type of valve. Ball valve is a valve in the 1950 s. For half a century, ball valve has developed into one of the main valve class. Ball valve is mainly used to cut off or turn on the medium, can also be used to adjust and control of the fluid. V-shaped ball valve can be more accurate to adjust and control traffic, and three-way ball valve is used to distribution medium, change the flow direction of medium.

are an important part of the society and they come in handy in any place where there are os&y valve in need of os gate valve.
Shenzhen Mech Valve Trading Co., Ltd. is committed to attracting, developing, and keeping a diverse work force that reflects the nature of our global business.
We take advantage of high technology to produce products that support safer and better quality and that enhance the using experience of gate valve.
While the productivity and efficiency benefits of automation are unequivocal for manufacturing wedge gate valve, the need for skilled humans to operate, utilize and advance technologies is equally unmistakable.
