Application of Gate Valves in Household Water Supply System - 2013-06-21 14:47:16

Valves are mechanical parts that can control the flow and pressure of fluids in piping or plumbing systems. Valves really function well in this aspect. We can stop and start the flow of fluid by opening up or shutting down the valves. We can control the amount of flow by setting soft seated butterfly valve to part open-up state. Some valves have the ability to change the direction of fluid flow. Valves are able to relieve pressure on components and pipes by regulating streams. They are indispensable for situations above. Various designs and types of valves are fashioned to satisfy all kinds of actual working needs.

Functionally speaking, there are Single Eccentric Butterfly Valve, gate valve, check valve, butterfly valve and dozens of others. Users have to select carefully according to their working conditions to ensure the applicability of valves. I'd like focus on the gate valve. Gate valve is highly recommended by the gate valve manufacturer for household piping and plumbing systems because of its user friendly property. It's easy for homeowners or laymen to operate on these gate valves.

According to the manufacturing materials, there can be Double Eccentric Butterfly Valve and cast iron gate valve for different situations. The cast iron gate valves are widely used in water supply system throughout German. This is because cast iron gate valves meet certain requirements: resistance to the constant soil movement; reliability and durability in usage even after many years; hygiene for a safe transport of drinking water. As a natural material, cast iron is chosen for its suitable characteristics as follows. Cast iron can serve a very long period of time. The material can bear internal and external impacts caused by soil or traffic. It is with high density which means a strong and sturdy structure. Its ability to resist corrosion is appealing. It is economically efficient because cast iron is one hundred percent recyclable.

In addition to the base material, outside coating is extremely important too. Good surface coating provides sufficient protection to the inside cast iron material. The gate valve manufacturer usually use pore-free powder coating or they may have the gate valves completely enameled. This extra layer of protection provides stronger resistance to corrosion, encrustation, and severe vibration. Enamel shows effective prevention from integral corrosion. The smooth and seamless surface can reduce the possibility for bacteria or germs to propagate. Fewer germs mean a smaller chance for the formation of bio-film which can contaminate our drinking water.
