Q: What valve is z45w gate valve?: Z = gate valve4 = connection: flange5 = structure form: dark rod typeW = sealing surface material: same as valve bodyDetails: JB/T308-2004 valve model preparation methods

Q: Why is gate valve or butterfly valve used for water pump?: General pressure is small, use the butterfly valve, when the pressure is big, use the gate valve. The two main function of the valve is to adjust the flow and easy to overhaul.Zibo Boshan new Duke water supply equipment

Q: Z45T-10 what kind of material is the gate valve?: JB/T 308 regulation3.7.4 nominal pressure of less than 1.6Mpa gray cast iron valve body material code, in the type of preparation to be omitted.So its body material is gray cast iron, the sealing surface is copper alloy

Q: What else, P54140V, 170V? What do they mean?: P work pressureP54 temperature at 540 degrees of work pressureThe pressure at P54 100 is 540 at the temperature of 100barV valve for chromium molybdenum vanadium steelP54 pressure 140V temperature at 540 DEG C for 140bar valve for chromium molybdenum vanadium steelP54 pressure 170V temperature at 540 DEG C for 170bar valve for chromium molybdenum vanadium steelFrom the JB/T4018 "valve type model preparation method"The standard unit is MPa, but it is usually used in bar

Q: Analysis of the advantages of elastic seat sealing gate valve?: General valve on the market for a long time there is Water Leakage or rusting, overcome the valve seal bad, rust and other defects, using the elastic elastic valve seat seal gate produce small quantities of elastic deformation of the compensation function to achieve a good sealing effect, with a switch to lighter and reliable sealing, good elastic memory and life and other significant advantages. The utility model can be widely used as an adjusting and intercepting device for pipelines such as water supply, sewage, building, petroleum, chemical industry, food, medicine, light industry, electric power, ship, metallurgy, energy system, etc.. This is the advantage and advantage of an elastic seat seal gate valve.

Q: What is a protective gate valve? What is gate valve knowledge?: Explosion-proof valve products, is a kind of safety valve can eliminate the shock wave which can stop the water hammer shock wave, it is a product composed of multiple sets of safety,

Q: What is the difference between Z41X gate valve and Z45X gate valve?: 2 kinds of valve function, there is no difference.Nothing more than a one with a bright bar. One is a dark pole.Dark pole is cheaper.Everything else is the same. Contact me if you need another valve. Zhejiang Futai Valve Co., ltd.. The contact picture is in the head.

Q: Gate valve z41t what does that mean?: According to the provisions of the JB/T 308-2004 valve type programming method:Z = gate valve4 = connection form: flangeT = sealing surface material: copper alloy

Q: Why does the centrifugal pump start and stop in the case of closing the gate valve?: After the valve is closed to stop the cause of centrifugal pump outlet valve is closed to stop the pump to prevent the flow back into the pump, impeller, impeller in reverse, part of the mechanical seal in the pump pump impeller reversal will have adverse consequences, serious damage to the centrifugal pump, to close the valve after the shutdown.

Q: What are the types and product categories of knife gate valves?: Definition of knife gate valve:Knife gate valve called knife type valve, knife gate valve, slurry valve, slurry valve, it is a gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, by the blade shaped gate can cut fiber material to cut off the media, there are two gate sealing surface, the valve gate pattern is the most common the two sealing surface to form a wedge, the wedge angle varies with the valve parameters, usually 5 degrees, the wedge type knife gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process of deviation, make up the sealing surface angle in the process. This gate is called the flexible gate.
