The Hongyuan designed for: valve, S316L stainless steel regulating valve: designed for: check valve regulating valve (Contact: 187,327,0358 QQ: 619688609) company mainly engaged in a variety of materials pipe: 304,304 L, 316,316 L, 321 310S ,18-8, 16Mn, 20 #, 20G, 12Cr1MoVG, P91, 10CrMo910, 15CrMo F51 petroleum, chemical, metallurgy, electric power, shipbuilding, machinery and other industries, such as pipes, valves, pressure vessels, condensers, heat exchangers , tower, manhole, hand hole flange joints sealed. Valve control components in the fluid delivery system, with a cut-off regulation, diversion, to prevent the counter-current, voltage regulators, shunt or overflow pressure relief function. Valves for fluid control systems, shut-off valve from the most simple to the extremely complex automatic control systems used in a variety of valve, a considerable range of varieties and specifications. The valve can be used to control the flow of air, water, steam, various corrosive media, mud, oil, liquid metal, and the radioactive media, such as various types of fluid. The valve according to the material divided into cast iron valves, cast steel valves, stainless steel valves, chromium molybdenum steel valve, chrome molybdenum vanadium steel valves, the duplex steel valves, plastic valves, non-standard custom valve material. Truncated class: such as gate valves, globe valves, plug valves, ball valves, butterfly valves, needle valves, diaphragm valves. Truncated class valve, also known as closed-circuit valve, globe valve, its role is to connect or disconnect the media line. (2) non-return categories: non-return valve, check valve, also known as the one-way valve or check valve, non-return valve is an automatic valve, and its role is to prevent the media back in the line, to prevent the pump and drive motor inverted, and the medium of the container leaks. Pump water off the bottom valve is a check valve class.
