Q:What does Z941H-25DN250 mean by electric gate valve (excluding electric equipment)?
9- electric (drive)4- flange connection (connection)1- plain wedge single gate valve (valve structure)H-Cr stainless steel (sealing surface material)25- nominal pressure is 25 kg, or 2.5MPa;DN250- valve by 250mm
Q:GB 300 gate valve, a multi?
GB DN300 flanged gate valve, PN10 manual 245kg bevel gear 315Other pressure levels, please specify specific pressure.Wenzhou Chaoda group Agel Ecommerce Ltd to provide the answer:
Q:Will the water supply and drainage to wear civil air defense gate valve, the use of bright rod or dark rod?
Water supply and drainage and civil air defense works, now with the dark rod type elastic sealing gate valve more.Compared to the gate and the traditional carve type or parallel double gate plate valve has the following characteristics: 1, soft sealing valve body, valve cover using precision casting foundry, a molding, no mechanical processing, do not use sealed copper ring, saving non-ferrous metals;
Q:What does gate valve DN80-PN16-QT450 mean?
DN80 means: liquid, internal thread connection, the valve sealing surface material for rubber, seat sealing surface material for lining adhesive, nominal pressure of 10 kg / cm2, nominal diameter of 80mm Iron Butterfly 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 are the differences between the gate valve and the cut-off valve?
The operating principle is different. The stop valve is an upward stem type, and the handwheel rotates and rises with the stem. Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open, the cut-off valve is not the same. The gate valve has no inlet and outlet direction requirements, and the cut-off valve has the required inlet and outletAt the same time, usually with the cut-off valve instead of gate valve, but the valve can also be used instead of cut-off valve. Valve sealing performance better, but the size is generally not large, the size of the gate valve can be done great.The main difference between them lies in:1, different structure, gate valve structure is more complex than the height, larger size, from the appearance point of view than the cut-off gate valve is short and high, especially the gate height space needs a higher open bar, the selection in the installation space under the condition of limited attention to.2, sealing surface, valve in the opening and closing valve and the valve seat surface always contact and friction between the sealing surface, and thus easy to wear, especially in close off the valve when the valve before and after the great pressure, sealing surface wear is more serious. And the valve once the valve is in open condition, it's seat and disc sealing surface between, not in contact,
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:What does gate valve Z41H-40 mean?
Z - that means gate valve (the initial letter of Zha)4---- is the connection form, which means flange connection1---- form of structure, which means Plain Bar wedge type rigid single gate valveH---- sealing surface overlaying ferrous carbide (initial letter of alloy steel He)40---- nominal pressure is 40 kg, or 4.0MPa, that is, PN10 at 250 degrees Celsius, the maximum working pressure is 40 kgThe material is cast carbon steel
Q:What does gate valve Z44T-10-200 code mean?
The meaning of the model is standard, the landlord himself to check the JB/T308 standard, Baidu library some, and is free to download:JB/T 308-2004 valve type method of preparation clear EditionHttp://wenku.baidu /view/5f798850ad02de80d4d84036.htmlZ = gate valve4 = connection: flange4 = structure form: double gateT = sealing surface material: Copper10 = nominal pressure: 1.0MPa, followed by no letters indicate body material: Cast Iron200 = nominal path: DN200
Q:What does "Z45W-10T" mean?What does each letter stand for?
For type PN10 Z45W Brass Gate ValvesZ is the valve type code, which represents the gate valve;Driving mode is hand wheel (code name omitted);4 is the connection form code, which represents the flange;5 is the gate valve structure form code, represents for the dark pole wedge rigid single gate;
