Q:I would like to ask how to access the valve?
May learn some basic knowledge of valves, learning in practice, relatively fast.
Q:Which direction is the valve? Which direction is it?
Generally: clockwise, counterclockwise, looseYou can also see the logo on the spool
Q:HH valve company in the United Kingdom, how about the valve?
Our factory boiler has this brand of valve, used for many years, has been no problem, really good.
Q:Ketem valve relative to other valve companies in the industry what are the advantages?
Floating seal: electric drive, electric ball valve flange connection floating ball straight, seal form with seal, the sealing surface of the valve seat material for hard alloy, nominal pressure PN16~PN63, nominal size DN15~DN200, suitable temperature of -28~500, the valve body is made of carbon steel or stainless steel. As a result of the use of hard sealing (metal seal), this valve is particularly suitable for particles, solids, slurry and other medium and high temperature and high pressure pipelines.
Q:What does "TD671F" mean?
You should type is wrong, or I should be D671F, with very limited knowledge and scanty information, this type of mean (D) pneumatic butterfly valve (6) of the clip (7) sealed the middle (1) fluorine plastic (F). There should also be a number of pressure figures and body material. For example, D671F-10C later means that the pressure is 10 kilograms (or 1.0MPa) and C represents the carbon steel
Q:Remove the handle and lever the stem rotation with a wrench,
1, carbon steel (WCA, WCB, WCC) applies to working temperature between -29 ~ 425 degrees between the middle and high pressure valve. Used for superheated steam. High temperature and low temperature oil, liquefied gas, compressed air, water, natural gas and other media.2 、 low temperature carbon steel (LCB) is suitable for working temperature between -46 ~ 345 Degrees of low temperature valve.3, alloy steel WC6, WC9 is suitable for the working temperature -29 to 595 degrees between the non corrosive medium high temperature and high pressure C5, C12, C12A for working temperature -29 to 650 degrees between the corrosive medium high temperature and high pressure valve.4 austenitic stainless steel for working temperature between -196 ~ 600 degrees corrosion of any medium valve.5,
Q:What's the valve as a unit?
Generally used as a unit of measurement
Q:How to better maintain the valve?
We should keep the valve cleanWe should regularly check and maintain the integrity of the valve the other components. As a fixed hand wheel nut fell off, to be filled and can not manage, otherwise it will grind the valve stem upper garden square, gradually lost with the reliability, and even can not startWe do not rely on the valve support other heavy objects, do not stand in the valveThe stem, especially the threaded part, to regular cleaning, the dust has been soiled should be replaced with a new lubricant, because the dust contains hard debris, easy to wear thread and stem surface, affect the service life
Q:What does valve J41H-16C mean?
J- stop valve4- flange type connection1- structure typeH- alloy steel seal16- nominal pressure 16 kgC- body carbon steel
Q:What does the valve "4" mean?
This is an inch inch size, 4 inches =1/2 = 25.4mm = 12mm
