Characterization forged globe valve socket weld J61H a closure member for linear movement along the centerline of the valve seat. Because stem to open or close the relatively short trip, but also has a very reliable cutting function, but also due to travel proportional to changes in the valve seat and the valve port valve is very suitable for flow regulation. Can be used in water, sewage, construction, food, electricity, medicine, metallurgy, textile, and energy on the fluid line for cutting or regulation and throttle use. Cut-off valves are generally welded flange connection or connection with the pipe connected. Optional drives are: hand wheel, bevel gear, electric, pneumatic. Structural features a cut-off valve is to rely on the stem pressure on the sealing surface of the valve seat sealing surface snug fit to prevent the media circulation. Is mandatory sealed valve. 2 medium flow shut-off valves have "low prices" and "high-low" two, only allowed one-way flow medium, directional installation. 3, cut in the form of structural valve body has a straight, DC type and right angle. 4, closing the valve open, the valve shut-off valve opening height of nominal 25% to 30% of the diameter, the flow already reached the maximum, which indicates that the stop 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 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 therefore smaller than the height of the valve shut-off valves, but the structure is longer than the length of the gate. 8, the opening and closing torque, compared with laborious. 9, fluid resistance, due to the valve body media path more tortuous, large fluid resistance, power consumption. 10, when fully open valve is often affected by erosion.

Order prompt a customer if the product has special requirements, must provide the following description in the contract:.... A length of the structure; b connection form; c nominal diameter, full bore, necking, pipe size; d use 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 and requirements of the model, both parties sign a contract under the same conditions to understand.
