Q: What is the difference between the copper gate valve and the ordinary material gate valve?!: The copper gate valve is made of copper alloy, and the common materials are made of stainless steel, cast steel, cast iron, and so on. Now there are new types of ceramic gate valves. Different properties of the gate valve performance, processing technology, service life, applicable occasions are a certain difference. Copper gate valves should be used for fire end water outlet installations as well as other occasions with special requirements.

Q: What is the difference between the model z81x-16q and z81x-16c of the groove gate valve?: Not 16qIs 16p, the former body is stainless steel, and the latter body is carbon steel

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: 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

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: Does the tap belong to a stop valve or a gate valve?: Most taps are stop valves:1, gate valve (gate valve) is a headstock ram, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed doors, discomfort pumpsparameters vary, usually 5 degrees is not high, medium temperature is 2 degrees 52'. To improve its manufacturability, make up for the deviation of the angle of the sealing surface during processing. This gate is called an elastic ram.2, valve (stop, Globe, Valve) of the opening and closing parts are plug shaped valve, sealing surface is flat or sea cone, the valve along the center line of the valve seat in a straight line movement. Stem form of exercise (generic name: dark bar), but also lift rotating rod can be used to control air, water, steam, all kinds of corrosive media, mud, oil, metals and radioactive liquid media and other types of fluid flow. Therefore, this type of shut-off valve is very suitable for cutting or regulating and throttling. Because of the valve stem to open or close the trip is relatively short, but very reliable cut off function, and because changes in the valve seat and the valve stroke is proportional, is very suitable for flow regulation.The stop valve is an ascending stem type, and the handwheel rotates and rises along 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 outlet!

Q: What kind of valve is gate valve? Is it different from the cut-off valve?: Gate valve is applied to the big diameter pipeline valve, the valve is generally used in small pipe diameter pipeline, their internal structure is different, the valve can not regulate the flow of water, the valve can be. If you want to understand in detail, it is recommended to take a sample of valve manufacturers to see the internal structure.

Q: What's the meaning of the gate valve model z41x 16Q?: Gate valve (Z) flange connection (4) wedge type single gate (1) rubber soft seal (X) -16 pressure) (Q)

Q: What does gate valve DN80-PN16-QT450 mean?: DN80 means that the nominal diameter of the gate valve is 80mm, and PN16 is the nominal pressure of the gate valve is 16Mpa. Q quick form T cast iron, 450 flanged connection single gate valve.

Q: Is the axial force and torque of the wedge gate valve the same?: See where you are, it is better to compare it: wedge type single gate valve features: a structure more flexible, gate valve is simple, sealing performance better than flexible gate valve or double gate valve.
