Q: What valve is z45w gate valve?: Cast iron gate valve with turbine head, please contact me

Q: How big valves and fittings need flange installation, such as gate valves, DN50, DN80 and the like?.: See, you choose 100 of the pressure is not high, you can not flange

Q: What are the meaning of the cast rigid gate valves z41h-16c?: According to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== flange connection1== rigid single gateH== sealing surface material: Cr13 stainless steel16== pressure rating: 1.6MPaC== body material: carbon steel

Q: What is the meaning of socket welding gate valve A105, D&S:STLT, STEM:13Cr, CL800, SW, AP1602, BB-BG-OS&Y?: Body material: A105Sealing surface material: STLStem material: 13CrPressure rating: CL800Connection: SWImplementation criteria: AP1602BB-BG-OS&Y: plain rod support, bolt connection, flange valve cap.

Q: What's the difference between open rod gate and dark rod gate valve?: 4, the dark pole gate valve height smaller size; Ming rod gate valve requires a larger installation space;5, the structure of the rod gate valve is beneficial to the lubrication of the valve stem, and the degree of opening and closing is obvious. The stem thread of the dark rod gate valve is not only unable to lubricate, but also directly accepts the medium erosion and is easy to damage. Therefore, the open bar gate valve is used more widely

Q: What is gate well?: Technical requirement:1: the valve itself can not seep, it must ensure its tightness;2: water supply pipeline during use, pipeline will be pressure from different aspects, which will produce different degrees of jitter or settlement, which requires the connection of water supply pipes and valves in the well to be reliable, able to adapt to a certain degree of jitter and settlement, and to prevent water infiltration into the well chamber in the pipeline valve wells; deep, slightly larger are generally made of cast iron valve (such as the cut-off valve, butterfly valve) iron valves long-term immersion in water, will affect the service life or cause fracture, so the sealing requirements are higher;3: valve shaft, shaft and well body, manhole cover way of connection should be reliable, not because of heavy rain or water seepage water into the well room.4: valve well is buried in the ground, to bear from different directions of different pressure, and different chemical substances corrosion and damage, and requirements of its pressure capacity and acid and alkali corrosion is better.

Q: What is the difference between Z41X gate valve and Z45X gate valve?: There is no difference in function. The two models are mainly made of different sealing materials,

Q: The valve safety valve check valve + + + = exposed part of a water pump adapter? Five: Generally do not require safety valve, just install exhaust valve in individual places.

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: What are the types and product categories of knife gate valves?: Knife gate valve drive mode:Manual, sprocket, electric, pneumatic, hydraulic, bevel gear, electronically controlled, hydraulic and pneumatic drive. Knife gate shape: bright rod, dark rod two kinds. Knife gate valve material: cast iron, cast steel, carbon steel, stainless steel, fluorine and so on. Knife gate valve seal: hard sealing, soft sealing, single-sided sealing, double sided sealing and other material seal.
