Product Structure
The German standard and national standardgate valves of Anix have reliable sealing, good performance and elegant appearance, in accordance with advanced national and international standards. The gate plates and the valve seats are wearing, high temperature and corrosion resistant, and have good scratch resistant performance and long service life. Wedge type elastic gate plate structure is used; roller bearings are provided for medium and large diameters to realize easy opening and closing; the valve rods are subject to tempering and surface nitrogen treatment and thus have good corrosion resistant and scratch resistant performance. Different pipe flange standards and flange sealing face types can be used to meet the requirements of different projects and users. There are a complete range of materials to be used for the valve bodies, and the packing and gaskets can be selected according to the actual working conditions or the requirements of the users. The valves are thus applicable to different working conditions with various pressure, temperature and media.
The American standard 、 Japanese standard globe valve of Anix is simple in structure and easily manufactured and maintained. The valve has small working stroke, short opening and closing time, good sealing performance, small friction on the sealing faces and long service life, suitable to be used for cutting off, regulating or throttling the media. The valve has relatively short opening or closing stroke of the valve rod and very reliable cutoff action. The valve seat and the flap are easy to be repaired; during replacement of the sealing components, there is no need to dismantle the whole valve from the pipes.
The high temperature and high pressure globe valve of Anix has a middle cavity of self tightening seal structure with good sealing performance. It is welded structure at two ends of the branch pipe. The valve flap and valve seat sealing faces are made of Stellite cobalt based hard alloy by buildup welding, and have good wearing, high temperature and scratch resistant performance. The valve rod is subject to tempering and surface nitrogen treatment. The bonnet packing box is of adequate depth, and the packing is added with corrosion inhibitor and sealed reliably. The valve is of back seal structure, which ensures no leakage along the valve rod during operation of the valve.
