Q: Gate valve Z41H-16Q generally used for what place?: Commonly used in petroleum, chemical systems, especially in long-distance pipelines of petroleum and natural gas.

Q: What kind of gate valve is Z6CS-H102?: Z== valve type: gate valve6== pressure rating: 800LB, API602C== structure: bolt connection, valve cover, bolt connection gland, bright rod support typeS== connection form: socket welding, that is, SWH1== body material: A10502== inner material: seat sealing surface STL, gate sealing surface STL, valve stem 13Cr

Q: greater than DN50 of the pipeline butterfly valve?: Have not heard of this requirement, before the ball valve and butterfly valve quality is rarely used now are good, can be used, but not easy to control the flow valve butterfly valve can close more time-saving, fluid resistance of small. HVAC branch pipe, to flow control, so the choice of gate valve and cut-off valve is more reasonable, and now choose a ball valve is also a lot.

Q: Why? God, can you explain to me in detail why?: The exit of the general pump is the first soft connection (shock absorber), followed by the check valve, and then the partition valve (such as butterfly valve, gate valve, cut-off valve, etc.), this is not the final answer.The question is interesting, and no corresponding information has been found in the relevant standards. We have also discussed the related issues, but differences of opinion is relatively large, the advantages of 1, first installed check valve installed after the valve or butterfly valve, check valve, can be protected, especially in a parallel pump, when the pump does not start, another pump starts when the impact force is gate valve or butterfly valve bear, disadvantages: gate valve or check valve who will protect? There have been a case of butterfly valve is broken. 2, first installed gate valve or butterfly valve installed after the check valve, advantages: can protect the butterfly valve or gate valve, the impact on the check valve to bear. Disadvantages: check valve who will protect, check valve by pressure difference switch, if the high pressure high pressure pipe, pump, if the flow is not stable, so check valve will repeatedly switch, will affect the check valve life. Personal opinion: check valve, check valve performance now have changed, many are using the slow closing check valve, so the impact force is two aspects to bear, because exports are not fully open the valve or butterfly valve, so you can put in check after the gate valve or butterfly valve valve. If not the slow closing check valve installed in the valve or the best after the butterfly.

Q: What is the difference between an elastic gate valve and a rigid gate?: One is cast iron, intermediate rubber gate, one is cast steel, and the other is steel flashboard,

Q: Does the tap belong to a stop valve or a gate valve?: If it is about to pull open and close, it is cock valveIf it is rotated up and down, it is a stop valve

Q: What is the difference between gate valve Z41T and Z45T?: The difference between Z41T and Z45T is that 41 is the dark rod, that is, the screw is not out of the turbine, and the 45 is the Ming bar, the screw out of the turbine outside, the price is also different?.

Q: Gate valve is gate valve, gate valve specifications, model code is generally what?: Valve lock plate valve, gate valve and code.According to domestic valve model standards, the valve model is by the valve type, gate valve drive mode, gate valve connection, gate valve structure, sealing material, valve body material code to indicate.1, gate valve type code named Z;2, gate valve drive mode code by letters, common 2- electric hydraulic, 9- electric, 6- pneumatic, 5- bevel gear drive, 3- turbo worm; manual do not need to write out;3, gate valve connection form code with letters to indicate, 1- internal thread, 2- external thread, 4- flange type, 6- welding, 7- pairs clamp type, 9- clamp, 0- card sleeve;4, the valve structure of code, 0- flexible wedge, 1- rod single wedge gate valve, 2- rising stem wedge gate valve, 3- parallel single gate valve, 4- parallel double gate valve, 5- dark pole single wedge gate valve, 6- dark bar wedge gate valve 7-, dark bar parallel gate valve, parallel gate valve 9- dark bar;5, sealing materials or lining materials were used R- T- austenitic stainless steel, copper alloy, X- rubber, S- plastic, N- nylon, F- fluorine plastic, H-Cr series stainless steel, hard alloy Y-, J- rubber, M- Monel alloy, Tc- ceramics;6, the body material code Z- K- gray cast iron, malleable cast iron, Q- ductile iron, copper and T- alloy, C- steel, P- chromium nickel stainless steel, R- stainless steel chromium nickel molybdenum, chromium molybdenum vanadium steel V-.For example: electric, flanged, rod wedge gate valve, sealing surface material by direct processing, nominal pressure PN0.1MPa of the valve body is made of grey cast iron gate valve: Z942W-1 electric wedge gate valve.

Q: Acid resistant alkali valve gate valve: A products have few connections and good overall steel quality.B closure speed is fast.C opening limit mechanism is convenient, flexible and precise.

Q: What is the difference between a flanged gate valve and a wire gate valve?: Flanged gate valves are flanged and must be welded to the flanges of the pipe, bolted together
