ZECO is a well-known supplier of forged steel gate valves for oil companies and industrial industries. Forged steel gate valves are named after the fact that their body covers are made of forged materials, and their materials cover ASTM A105, ASTM A182 F11, ASTM A182 F5, ASTM A182 F304, ASTM A182 F304L, ASTM A182 F316, ASTM A182 F316L and so on. The forged steel gate valve is usually smaller than 2 inch, but due to its high pressure resistance, the pressure pound class can be CL2500, and the working temperature can reach -29℃ to -500℃. It is widely used in oil and gas pipelines and other industrial fields.
ZECO forged steel gate valve is equipped with reduced diameter design. Compared with cast steel gate valve of the same diameter, the medium flow rate is slightly smaller, but the pressure and temperature tolerance range are much higher. Meanwhile, ZECO can also produce full diameter design for users. ZECO forged steel gate valve has three types of valve body bonnet connection, the most common is the first bonnet bolt connection is also commonly known as the BB structure, the seal between the body covers is wound gasket seal, this structure is convenient for maintenance, in special cases of the valve need maintenance, disassemble the bonnet can be online maintenance; The second is the body bonnet by welding way, body and bonnet welded seal without leakage point; The third is the pressure self-tightening bonnet, bonnet and bonnet using thread connection, internal pressure self-sealing ring seal, through the use of high pressure working conditions, the greater the pressure, the better the sealing effect.
