Q:What do letters represent in the QF-2 and PX-32 valve models?: You check it on the national standard! One is accurate!

Q:Valve pressure grade division: 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 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, chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..

Q:How to better maintain the valve?: How to maintain the valve?Enter the same as other mechanical products, but also the need for maintenance. This work well, can extend the service life of the valve, the following will introduce the valve maintenanceStorage and maintenanceThe maintenance of the purpose is to keep the valve in the custody of the damage, or lower quality. In fact, improper storage is one of the important reasons for valve damageThe valve custody, should be arranged in good order, a small valve on the shelves, large valves can be neatly arranged in the warehouse on the ground, not arbitrary lumber pile, do not let the flange face contact with the ground. This is not only for beauty, mainly to protect the valve, not to touch badBecause the storage and handling properly, hand wheel broken, crooked stem touch the fixed nut hand wheel and stem loosening loss and so on, these should avoid unnecessary losses.We temporarily on the short-term use of the valve, should remove the asbestos packing, in order to avoid electrochemical corrosion damage to the valve stem.I just entered the library on the valve, to conduct inspections, such as during transport into the water or dirt to wipe clean, re storedThe import and export of valves to use wax paper or plastic sheet sealed to prevent dirt insideThe valves on the machined surface rust in the atmosphere should be coated with anti rust oil, protectI placed outside the valve, must be covered with linoleum or tarpaulins like rain, dust items.
