ZECO is one of the professional gate valve manufacturers, specializing in the production of wedge gate valve and through conduit gate valve products, two types of API 6D production for nearly 30 years, ZECO technology also with China valve association secretary-general of the general and technical consultants are in the same year, other disciples which brought ZECO very powerful technical support, have also brought ZECO to interact with the technology of the Chinese valve association is very frequent, and it is why a solid technical force, ZECO obtained also have 30 a few related gate patents, participate in national valve standards there are 10 items. Among those motorized gate valve suppliers, ZECO valve provides high-quality products and deserves trust!
According to the structural form, the gate valve can be divided into Wedge gate valve, through conduit gate valve, slab gate valve, and industrial gate valve. The structure difference is distinguished by the wedge, the wedge and seat of wedge gate valve are degrees, generally, 3 degrees, 5 degrees, the wedge and seat of through conduit gate valve are parallel, through the medium pressure from floating seat or wedge to seal
The drive mode of the gate valve can be divided into manual, pneumatic and electric, gear operated and motorized. The choice of operation mode is mainly based on the requirements of clients. ZECO can configure the operated actuators and brands required by clients.
When selecting the valve body material of the gate valve, the material should be determined according to the actual conditions of working conditions such as temperature, pressure & medium. Body materials of ZECO gate valves include, but are not limited to stainless steel, wcb, carbon steel, forged and cryogenic.
The size of the pipe determines the size of the gate valve and the rate of flow required through the gate valve is considered first. ZECO international standard valve company manufactures the ball valve of smallest 1/2 inch, 2 inches, 3 inches, 4 inches, 6 inches, 8 inches, 12 inch and maximum 56 inches.
Gate valves are a major product in API 6D. Gate valve is divided into API 600 and ASME B16.34 according to API standard, which can be applied to low, medium and high-temperature pressure conditions. It basically covers the whole pipeline of petroleum, chemical and natural gas industry. Therefore, the proportion of gate valve in the industrial valve is the same as that of ball valve, which is a very important product.
The industrial gate valve is simple in structure and reliable in use. The wedge is closed and tightened slowly by the inclination and finally achieves the complete sealing condition. On the one hand, it depends on the professional design of technicians, on the other hand, it depends on the professional technology of production line personnel. Gate valve features a lot of, but on the pipeline is particularly important in the fully open position, is equal to the pipe size, meaning that the gate valve is installed directly under the state of full open section pipe, no resistance to medium, which is why the gate amount is so big, because there is no flow resistance and the dielectric saved the cost of the pipeline, with monthly is very large.
