ball valve Q45

ball valve Q45

Ball valve Q45 is a kind of ball valves. Q45 is the model number for the ball valve. The body materials of the ball valve Q45 are WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8(304), CF3(304L), CF8M(316), CF3M(316L). The nominal pressure or pressure level of the ball valve Q45 is from PN1.0 to 32.0MPa or from ANSI CLASS 150 to 900 or from JIS10 to 20K. The nominal diameter ranges from DN6 to 900. As for the applicable temperature, ball valve Q45 ranges from - 196 ° to 540 degrees Celsius. The ball valve Q45 can be connected by flange, butt-weld, thread and socket weld etc. besides, it can be driven by manual, worm gear and worm rod drive, pneumatic, electric, gas hydraulic linkage, and electro-hydraulic linkage. The ball valve Q45 is ideal for the medium such as water, steam, oil, nitric acid, acetic acid, oxidizing and so on. The design and manufacture for ball valve Q45 are in accordance with BS5351 and GB 12237-89. as for the face to face, it complies with ANSI B16.10 and GB12221-89. The flange dimension for the ball valve Q45 conforms to ANSI B16.5, JIS B2212-B2214 and JB/T79-94.

The ball valve Q45 has the similar working principle with the ball valve. The ball valve Q45 is opened by turning handles attached to balls inside the valves. The ball has a hole or port through the middle. When the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked. Ball valve Q45 not only has a simple structure, good seal performance, but also in a certain nominal diameter scope, small in volume ,light in weight, small material consumption and installation size, and driving torque small, simple operation. Ball valve Q45 is widely used in petroleum, chemical, liquefied petroleum gas, water, food, pharmaceutical, power generation, papermaking, urban construction, mineral, boiler steam system, the municipal administration, the atomic energy, aviation, the rockets departments, and people's daily life.
