Q: What is the use of each brand in the super high-rise, commercial complex, hotel? Price comparison of each brand? In the general valve, balance valve, electric valve, who did the best? Any knowledge about the valve, please ~ ~ thank you for your generous with your criticism: Johnson, SIEMENS, Honeywell is mainly in the electric valve inside, because they themselves do automatic control system, so the electric valve matching is strong, but also manufacturers own production, other types of valves they several brands are generally looking for OEM agents do, is not recommended.

Q: What does the J41Y-100I valve type mean?: Stop valve typeJ represents the cut-off valve, 4 (flange) on behalf of his connections, 1 (straight) on behalf of his structure, Y (seal) on behalf of his seat sealing surface or liner material code, 100 is the nominal pressure value, I (chrome molybdenum steel) is the code of the body material

Q: the valve to an electrical signal, with this signal to control other components, ask: what valve?: Online search "air switch", many suppliers.You may choose your pipe according to your pipe diameter.The flow meter can also be used to control the flow of operation

Q: A kitchen, 2 bathrooms, in addition to the toilet, toilet (only cold water), the rest need hot and cold water supply, and hot water by solar water heaters and gas water heater selection. The kitchen is mainly a sink, each toilet for toilet, shower, washbasin, separate cold water faucet. I don't know how many metal materials I'll use now Thank youThe waterways are all dark!: PP-R ball valve (cold hot water pipe valve): solar water heater 2, gas water heater 2, 2 hot water pipe switching with 1, indoor main water supply valve 1, 2 toilet water supply valve 1, total 8.Eight character valve (angle valve): kitchen, dishes, basins 2, toilet, toilet 2, wash basin 4, total 8.Other: shower water mixing valve 2, water washing machine 2, 2 washbasin faucet, basin faucet dish 1.The water supply of solar water heater and gas water heater is calculated according to the hard connection of PP-R pipe.

Q: The total valve of my natural gas was closed by the attitude I tried. Now I can't open it. I need to use gas. Who knows how to drive it? What skills do I have? I'm talking about the main valve.: Are you talking about using air? Or your valve is a pneumatic emergency shut-off valve

Q: What items and detailed procedures should be inspected for valve size inspection?: The American Standard (American Society of mechanical engineers ASME B 16.10-2000). Internet access can be downloaded, such as free standards to share and download sites. If you need any other valve standard, send me the mailbox.

Q: How to better maintain the valve?: Use and maintenanceThe maintenance of the aim is to extend valve life and ensure reliable opening and closingThe stem threads, often with the stem nut friction, to a little yellow dry coating oil, molybdenum disulfide or graphite, lubricationWe do not often open and close the valve, but also on a regular basis handwheel on the stem threads to add lubricant to prevent bitingThe outdoor valve, to increase the protection sleeve on the stem, to rain, snow, dust and rustIf the mechanical valve system to be fixed, to add time to the gearbox oil

Q: Excuse me American Standard pressure test valve GB standards are much ~ is how much valve pressure can play much pressure? Thank you: Strength test is nominal pressure of 1.5 times, the test time is 5min, the test time, the valve body is not broken, no deformation, the valve is not leaking water, the pressure gauge does not drop to qualified. After the strength test has passed, the tightness test is carried out. The tightness test pressure is equal to the nominal pressure. The valve does not leak in the test time, and the pressure gauge does not drop to be qualified.

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.

Q: Is there any difference between the valve and the water valve?: Oil valve with water valve is that the oil valve is over the oil, and the valve is over water, the type of fluid is not the same.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..
