- Q: Z11H/Y forged steel gate valves H/Y what does that mean?SZ45H S what do you mean?Blow 2Z41YGY-40P, what do you think?What does NKZ61H vacuum valve NK mean?What does DS/Z64H water seal valve DS mean?Specific valve number how to see ah, detailed information, thank you!

Table 10 the sealing surface of the valve seat sealing surface or liner material code or liner material code sealing surface or lining material code or code of lining material tin based bearing alloy seal (Babbitt) B Monel M alloy T enamel C nylon plastic rubber X N steel boriding nitriding steel D P hard alloy Y fluorine plastic lining F lead Q ceramic G austenitic stainless steel R Cr13 stainless steel H S note: the plastic body directly processed seat sealing surface material code with "W". When the sealing surface of the sealing material is not the same, the material name is indicated by the material with low hardness. The value of the nominal pressure of 10 times, according to the number of MPa (1MPa=106Pa). The valve body material code represented by the letter, in accordance with the provisions of table 11. Table 11 the valve body material body material material code code code C chromium nickel molybdenum stainless steel R Cr13 stainless steel H S plastic steel chromium molybdenum copper and copper alloy I T malleable cast iron titanium and titanium alloys K A L Aluminum Alloy CrMoV V Cr Ni stainless steel P Z gray cast iron ductile iron Q. In the original standard of nominal pressure equal to or less than 1.6MPa gray cast iron and the nominal pressure is greater than or equal to 2.5MPa carbon steel valve omitted the code.
- Q: How to identify the good or bad of the valve, without pressure test and instrument?
- First, the appearance, two according to the standard to see flange thickness, outer circle, wall thickness and other dimensions are standard, 3 see details.
- Q: Ketem valve relative to other valve companies in the industry what are the advantages?
- The electric actuator built-in servo system, no need to add servo amplifier, input 4-20mA signal and 220V AC power supply can control the operation. Compared with the ordinary electric ball valve, the utility model has the advantages of compact structure, small size, light weight, close distance between the valve seat and the end face flange, less material retention, superior sealing performance, etc..
- Q: Chinese valve and a valve which is better?
- Look what valve you use, ah, these two can be ah!
- Q: What's the difference between valves and valves without valves?
- The difference between a valve with and without a valve is that it has the advantage of having the valve exhaust. The advantage of the valve is that it can control the amount of exhaust and prevent the discharge of other fluids.Valve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
- Q: Which direction is the valve? Which direction is it?
- Ball valve: handle and Guan Daocheng 90 degrees for the pass, 180 degrees to open (ie in line with the direction of the pipe open)The gate: clockwise, counterclockwise.
- Q: What do letters represent in the QF-2 and PX-32 valve models?
- This is the material code, specific check: valve code. Just OK
- Q: What is the difference between a stop valve (a power station valve) and other valves?
- Power station cutoff valve advantages editor1., the fluid resistance is small, and the coefficient of resistance is the same length as the pipe section.2., simple structure, small size, light weight.3., reliable and reliable, the current gate valve sealing surface materials widely used plastic, good sealing, vacuum system has also been widely used.4 easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control.5., easy maintenance, simple valve structure, sealing ring is generally active, disassembly and replacement are more convenient.6. in full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, it will not cause erosion of the valve sealing surface.7., a wide range of applications, from small diameter to a few millimeters, large to several meters, from high vacuum, high pressure can be applied.
- Q: Excuse me American Standard pressure test valve GB standards are much ~ is how much valve pressure can play much pressure? Thank you
- The standard is different, the test is not the same, what kind of valve you, a domestic valve only do stress testing, in fact, the pressure can generally be guaranteed, many are bad at high temperature or life testing above
- Q: How does the valve close?
- This is a relatively vague ah, like the stem ah, usable spanner clamping, clockwise rotation in the end. The handle should be closed groove and the coincidence place.
