There are three kinds of common valve core: stainless steel ball valve, ceramic valve and roll shaft valve.because it is not affected by water impurities or shorten service life.we can not see the valve when we are buying faucet,but we can simply judged the quality of valve based on hand feeling when turning handle.
valve element is one of the most important parts for faucets, valves and other fluid control system components.Compare to steel ball valve,ceramic valve has good better performance in heat-resisting wear-resisting,also ceramic valve have good sealing performanceso,so its lifetime is very long and with so much opening times,not easy to cause water nozzle leaking for wear and tear of valve.
steel ball valve and ceramic valve is the common faucet valve. affordable,less water pollution, good wear resistance,good sealing performance,and improvements for the “brittle”,to make ceramic valve been widely used.Currently,most faucet had been used ceramic valve on the market.Insiders think that this valve is suitable for poor water quality area. Valve is a component which with direction control,pressure control or flow rate control by its interior turning.Steel ball valve is good at resist pressure, but the drawback is the seal rubber seals is easy to wear and tear.
Taiwan:KCG valve,Hain-Yo valve
China:Wanhai valve,Mingshi valve
many international valve brands had built factory in China to supply the mainland directly,such as Sedal, KCG
Ceramic valve:deformation of ceramic material is very small,has higher bonding strength than metal.
valve element is one of the most important parts for faucets, valves and other fluid control system components.Especially for certificated faucet,like upc faucet,the valve need to be approved,like Sedal valve.And steel ball valve handle have larger turning angle to control temperature accurately,ensure hot water Plastic Angle Valve can be flowed promptly and accurately to saving energy.Turning off/on the faucet in half,the handl feeling of upper half and lower half is not different(just high-grade valve have this characteristic)Good valve,you will feel very slight when you are turning off/on faucet.
However, the cost of stainless steel ball valve is higher than other types,and production process requirements is much higher,suitable for poor water quality area.
Stainless steel ball valve is high-tech content,some high-grade sanitary ware brand use laser technology processing irregular seven hole stell ball valve, as a new faucet valve for the newest product.Each faucets’s switching control needs a valve,the quality of valve is the important evidence to assess the quality of the entire faucet,or you can think the most important thing to faucet is valve. The common characteristic of these 3 valve is:the valve is integral,easy on installation maintenance and replacement. But as old-fashioned valve,it has been gradually can not meet the demand of people for valve,so will gradually eliminated by the market. Generally,without block sense,feeling slight,that may be a good valve,but not 100% sure.
“simple way” to identify faucet valve:
- To feel if there is blocked feeling when you are turning off/on the faucet(if so,the valve is bad).
Also turning off/on the faucet,to feel if there is oil damping feeling, blocking feeling,if no blocking feeling and with damping feeling,just buy it
.The faucet with ceramic valve,hand feeling is more comfortable, smooth,open and close rapidly.And ceramic have high performance in tensile strength, compressive strength, elastic modulus and hardness,However,ceramic is “brittle” and difficult to machining,limits its application scope
Over the last decade, due to the development and progress of martensitic phase change toughening technique, composite Technology and nano-ceramic,had made greatly improved for “brittle” of ceramics,its Silicone Kitchen Faucet toughness and strength has been greatly improved, applied range is also expanding, such as the application as the faucet valve to be greatly welcomed.
The advantage of roll shaft valve is: handle rotation smooth, easy to operate,comfortable hand feeling, ageing resistance, resistance to wear. Roll shaft valve core is very rare in common faucets
