water oil gas rising casting steel rising stem gate valve
1.Class A sealing
2.DN50-600
3.can put your logo on the valve

1.Product description

The gate valve can only be fully opened and fully closed to be used for cutting in the pipe-

line. It has such features as unlimited installation direction, small disturbed current, low press-ure drop, shorter face-to-face dimension, good sealing performance and wide application range.

1.This kind of Russian standard valve reach Class A sealing effect and Guarantee no leakage

100%.It has widely used in the fields of oil and gas etc,under the pressure of 1.6 mpa.

2.Sealing surface is made of stainless,can serve a long life.

3.Use of flexible graphite packing,sealing and reliable,easy operation.

4.Brass yoke nut and stainless stem will never get rusty,more easy operation.

5.Ductile iron handwheel have enough tenacity and breakage-proof.

Q:What does Z941H-25DN250 mean by electric gate valve (excluding electric equipment)?: Cast steel flanged gate valve 25 pressure bore 250

Q:Gate valve, butterfly valve, ball valve advantages and disadvantages? What are the usual valves?: Commonly used valves are: gate valve, globe valve, check valve, ball valve, butterfly valve, safety valve, regulating valve, plug valve and so onValve: valve is closed parts (RAM) vertical movement of the valve in the pipeline along the channel axis, used primarily as a medium cut that open and close use. In general, the valve can not be used as a regulation flow. The utility model can be applied to low temperature pressure, and can also be applied to high temperature and high pressure, and can be made according to different materials of the valve. But the valve is generally not used to transport mud and other media pipeline.Advantages: fluid resistance is small; the opening and closing torque needed by the smaller; can use the ring pipe flow to the two direction in the medium, that is to say the unrestricted flow of medium; the fully open, the sealing surface by the erosion of the working medium is smaller than the cut-off valve; the body has the advantages of simple structure, manufacturing good craft; the structure of relatively short length.Disadvantages: the size and height on the larger required installation space is larger; in the process of opening and closing, a relative friction sealing, friction is large, even scratch phenomenon caused by easily at high temperature; the valve has two sealing surface, to processing, polishing and maintenance of some increase the opening and closing time difficult.

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:Z45T-10 what kind of material is the gate valve?: Z45T-10 refers to the nominal pressure of 1Mpa gray iron valve. The meaning of letters and numbers is:(Z) - gate valve;(4) indication - internal thread connection;(5) indicating dark wedge rigid single gate;(T) - the body is made of copper or copper alloy;(10) indication nominal pressure 1 mpa.Is the gate valve 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. The gate has two sealing surfaces, and the two sealing surfaces of the most commonly used gate valves form wedge and wedge angle valves.

Q:What are the types and product categories of knife gate valves?: Knife gate valve drive: manual, electric, pneumatic, hydraulic, bevel gear, electro hydraulic and pneumatic drive.Knife gate shape: bright rod, dark rod two kindsKnife gate valve material: cast iron, cast steel, carbon steel, stainless steel, fluorine and so onKnife gate valve seal: hard sealing, soft sealing, single-sided sealing, double sided sealing and other material seal.

Q:What is the soft seal gate valve?: Cautions for installation and maintenance of soft sealing gate valve:For double gate valves, the direction of installation shall be in the vertical position of the valve stem, and the handwheel at the top.The installation of the soft gate valve shall be carried out in strict accordance with the installation environment, installation conditions and installation procedures on the factory manual.After installation, the soft seal gate shall be periodically checked for performance and killed in the cradle before any undesirable conditions occur.

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 is an inverted seal gate valve?: When the inverted sealing gate valve is fully opened, the sealing of the sealing is brought together, and the sealing effect is reduced, and the erosion of the filling to the fluid is reduced, and the service life of the filler is prolonged, and the possibility of leakage is reduced. Generally on the gate valve, stop valve has inverted sealing requirements.

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 type of flange does it fit with the gate valve?: According to the welding plate flange, flange material selection of piping material.
