Q: What is the difference between gate valves Z41W-16R and Z41W-16P?: According to JB/T308P stands for Cr-Ni stainless steelR stands for Cr-Ni-Mo stainless steelCr-Ni stainless acid resistant steel has CF8, CF3, F304, F304L, which applies to the medium of work, such as nitric acid oxidation acid.Cr-Ni-Mo stainless acid resistant steel has CF8M, CF3M, F316 and F316L, which is suitable for working medium, such as acetic acid and reducing acid.

Q: Gate valve Z41H-16Q generally used for what place?: It is a standard flanged gate valve with engineering pressure 1.6MPa. Generally used in chemical processes, of course, can also be used for municipal and civil engineering. The valve is generally used for cutting occasions fully open or fully closed, is not suitable for flow regulation.

Q: How about the model of stainless steel gate valve?: Stainless steel gate valve is divided into 304 stainless steel gate valve, 316 stainless steel gate valve, 321 stainless steel gate valve. The expression is: Z41H-16P.

Q: What are the features and uses of the gate valve?: 1) advantages: sealing performance than the cut-off valve, the fluid resistance is small, open and close more effort, full sealing surface by the erosion of media, media flows from the restrictions, with double flow, small structure length, wide application range. 2) disadvantages: high size, open need a certain space, opening and closing time is long, in the opening and closing, the sealing surface is easy to erode and scratch, and the two sealing pairs bring difficulties to the processing and maintenance.3) use: gate valve is generally used in the caliber of DN15-1800mm pipes and equipment, and its dosage is great, mainly cutting off function, not allowed to throttle.

Q: What is the difference between cut-off valve and gate valve?: Simply put, the cut-off valve is one-way, only into, do not give up, the valve is two-way

Q: Which is more expensive, bronze gate valve or brass gate valve?: The casting and workability of brass are much better than that of stainless steel, especially the valve with more complicated internal cavity.

Q: What is the allowable leakage rate of the gate valve D?: In GB/T 13927, the leakage rate of the valve is divided into 10 grades, namely: A, AA, B, C, CC, D, E, EE, F, G class. And stipulates that when the order contract does not specify, the metal sealing valve according to D requirements.

Q: The main question is, what are the functional differences in which case?: The gate (gate valve) is a gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle gate valve. The direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle.Gate valve advantages: 1, fluid resistance is small,.2, opening and closing more labor-saving,.3, medium flow unrestricted, not disturbed flow, do not reduce pressure,.4, simple shape, structural length is short, manufacturing process is good, a wide range of applicationsValve shortcomings: 1, between the sealing surface is easy to cause erosion and abrasions, maintenance is more difficult,.2, big size, open need some space, opening and closing time is long,.3, the structure is more complex

Q: Fire protection gate valve from the wall how many distance there is no regulation?: Don't know don't answer. "According to the provisions of article 6.2.13 GB50038-2005" code for design of basement for civil air defense engineering, into or through the door unit between the door closed wall should be set up in the inner side or two nominal pressure pipeline is not less than 1.0MPa, the spool is stainless steel or copper gate or globe valve water pipe from the air enclosure structure. The installation position from the wall should be not more than 200mm.

Q: What are the standards for the execution of cast iron dark pole gate valves?: Four, summary:1, cast iron gate valve is mainly used as a connection and cut off the role of medium. The opening and closing parts of the valve are ram, and the direction of movement of the gate is perpendicular to the direction of flow of the medium. Cast iron gate valve with ductile iron as the main material, the weight is very light, only about 20%~30% of the traditional gate valve;2, cast iron hidden rod gate valve belongs to the class of products, but also the successor to the traditional gate valve, the use of gate generated by the deformation of the compensation role, so that the valve to achieve good sealing effect. Cast iron dark rod valve with open and close the advantages of convenient, reliable sealing, good elastic memory, long service life, can be widely used in metallurgy, electricity, sewage, medicine, construction, food, textile, tap water, energy and other pipeline regulation and closure devices as.
