Characterization Luo molybdenum steel globe valve GB WC6 a valve closure member for linear movement along the centerline of the valve seat. Since the stem to open or close the relatively short trip, but also have very reliable cutting function, but also because the trip is proportional change in the seat and the valve port valve is very suitable for flow regulation. Can be used in water, sewage, construction, food, electricity, medicine, metallurgy, textile, energy, fluid lines for cutting or regulation and throttle use. Cut-off valve is usually flange connection or welded connection with piping connected Optional drives are: hand wheel, bevel gear, electric, pneumatic. Structural features 1, the cut-off valve is to rely on stem pressure on the valve sealing surface and the seat sealing surface snug fit to prevent the media circulation. Is mandatory sealed valve. 2, medium flow shut-off valves are "low prices" and "high-low" two, only allowed one-way flow of media, directional installation. 3, the cut-off in the form of structural valve body are straight, DC and right angle. 4, when the cut-off valve is open, the valve opening height of the cut-off valve nominal 25% to 30% of the diameter, the flow already reached the maximum, which indicates that the cut-off valve has reached the fully open position. 5, the cut-off valve structure simpler than the gate, manufacturing and maintenance are more convenient. 6, the sealing surface easy to wear and abrasion, sealing, and no relative sliding between the valve and the valve sealing surface when opening and closing, and thus wear and scratches are not serious, good sealing performance and long service life. 7, when opening and closing, the valve stroke is small, and thus the height of the cut-off valve is smaller than the gate, but the gate is longer than the length of the structure. 8, the opening and closing torque than laborious. 9, fluid resistance, due to the valve body media path more tortuous, large fluid resistance and power consumption. 10, when fully open valve is often affected by erosion.

Usually prompts customers as the products have special requirements, shall provide the following description in the contract:.... A length of the structure; b connection form; c nominal diameter, full bore, reduced in diameter pipe sizes; d use of media and temperature and pressure range;. e testing, inspection standards and other requirements. Second, the factory can configure various types of drives according to customer specific requirements. Third, as provided by the customer to determine when the valve type and model, the customer should correctly explain the meaning of the model and requirements contracts under the same conditions of supply and demand sides understand.
