Q:What is the Z15T-16C letter of the gate valve?
The Z class code indicates the type of gate valve, gate valve is the first letter of the alphabet. The gate is manual driving mode, 1 said the connection form of gate valve for connecting thread, 5 represents the structure form of gate valve for rigid single gate, T gate said lining material of copper alloy, 16 PN1.6MPa nominal pressure valve. C said the valve body material is carbon steel.
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:The difference between gate valve and butterfly valve, as well as cut-off valve,
The gate valve is one of the simplest valves. Generally manual, most of the electric valve failure, as a manual. Butterfly valve is more, I saw the pneumatic butterfly valve, that is, with gas control closed, general and solenoid valve matching.Without strict conditions and advantages and disadvantages, of course, the equipment requires a relatively high degree of automatic control. I can check it out on Baidu.
Q:What do you mean by forged steel gate valves 800LB DN20 SW?
Is the forged steel gate 800LB is DN20 on SW welding pressure
Q:What gate valve is the J41H-150LBDN100 gate valve?
Its closing principle is to rely on the valve bar pressure, so that the valve sealing surface and seat sealing surface close together, to prevent the circulation of media. The cut-off valve is divided into three kinds: straight through type, right angle type and direct current type oblique stop valve.
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 does gate valve DN80-PN16-QT450 mean?
The outer diameter of the pipe is usually 89mm;"PN16" means the nominal pressure of the gate valve is 16Mpa;QT450 QT said, nodular cast iron, tensile strength is more than 450MPa 450.
Q:What does valve qz45x - 10q mean?
Crown valve pressWhat does Q stand for? I'm not sure. It's probably made of ductile iron"Z" means "gate valve"4 represents flange connection5 represents the dark bar (1 represents the Ming pole)X stands for rubber seal and soft seal10q stands for 10 pressure
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:Gate valve type Z40Y, Z40H letters - what does that mean?
According to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== connection: flange0== structure: wedge type elastic RAMY== sealing surface material: hard alloyH== sealing surface material: Cr13 stainless steel
