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?: J41Y-100I flange type chrome molybdenum steel valve forgingJ 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: How to identify the good or bad of the valve, without pressure test and instrument?: You can see what the material inside the valve ~ basically copper heart relatively durable, solid ~!

Q: What does the valve "4" mean?: An inch of eight points, home tap, valve is generally 4 points

Q: What does the "Z45T-16" valve mean?: Z - gate valve4 - flange connection5 - Dark pole, stem non lifting (gate valve structure)T - copper alloy, valve sealing face code16 - pressure code, 1.6MPaMaterial code for grey cast iron valves of nominal pressure less than or equal to PN16 shall be omitted in model preparation.May refer to JB/T 308 valve model compilation method

Q: What should be checked before using the valve?: 5, check valve disc or spool movement is flexible and accurate, no bias, displacement or skew phenomenon6, spring-loaded safety valve should be sealed, positioning lever type safety valve should have the weight of the device7, rubber lining, lining enamel and plastic lined valve body surface should be smooth, the lining layer and the substrate firmly, no crack, blister defects, using high frequency electric spark generator to inspect the lining surface, not found in liner breakdown (white flash phenomenon) is qualified8, the valve flange sealing surface should meet the requirements, and shall not have radial scratches

Q: Why can't the clip type check valve be directly connected with the pipe mouth or other valves?: The clip type check valve is made up of two discs to prevent backflow.If the clip check valve is connected to the other valve, the disc may touch the valve and cause the check valve not to be fully opened or closed. This is a preliminary analysis of "enter the valve", for reference only!

Q: What is the diameter of a general pipe valve?: What a big pipe? The normal valve clearance is 1cm
