how to choose the high quality stainless steel valves? Visual valve when the choose and buy, appearance should be without sand holes; Plating surface should be uniform luster, attaches great importance to the presence of peeling, cracks, burning, grinning, fall off, shading, and significant disadvantages such as pitting; Spraying appearance uniform arrangement should be fine, lubrication, shortcomings and so on can not have sag, grinning.

a common sense, understand stainless steel valve:

civilian valves now commonly used ordinary families usually have a stainless steel gate, stainless steel valve, triangle valve, usually iron or copper. Because of the copper alloy mechanical performance is good, is not easy to rust, corrosion resistance, strong strength, thus copper Industrial Valves has been gradually replaced the iron valves. Triangle Industrial Valves appearance of anything and choose plating, it is not only the effect of manipulation of the pipeline medium flow, also can rise to decorate the effect. Triangle Industrial Valves normally connecting pipes inflow hoses for water mouth, sit implement water supply, also have a cohesive inflow hose pipe used for water supply of water heater. Gate valve used for pipe and water meter of cohesion; Ball valve used for pipeline and water heater cohesion; Because the ball valve open/close than gate valves is convenient, the linkage between the pipe and water meter now also most choose ball valve.

2, master the choose and buy of civil stainless steel valves: should be different according to user's request choose different types of household valve:

1, visual valve when the choose and buy, appearance should be without sand holes; Plating surface should be uniform luster, attaches great importance to the presence of peeling, cracks, burning, grinning, fall off, shading, and significant disadvantages such as pitting; Spraying appearance uniform arrangement should be fine, lubrication, shortcomings and so on can not have sag, grinning. These shortcomings will directly affect the service life of the valve.

2, valve pipe thread is the linking to the pipeline, visual thread appearance when the choose and buy any dent, broken teeth, such as significant disadvantages, particularly to the pipe thread and cohesion of a spin and useful length will affect the reliability of the seal, when the choose and buy should attach great importance to the available length of pipe thread. Usually DN15 cylindrical pipe thread useful around 10 mm length.

3, gate valve, ball valve is usually marked on its body or handles nominal pressure, when the choose and buy can choose according to their needs.

4, replace the existing gate or ball type valve, to clarify the length of the structure, avoid buying the device.

5, triangle valve pipe thread has two kinds of female and male, according to the demand of choose and buy; Also pay attention to is now in the market have some triangle valve, zinc alloy valve of the price is usually lower commodity, but easy to corrosion and rupture.

6, should as far as possible in the normal building materials stores, supermarkets, such a stainless steel valve products quality is to ensure that.

The global market was valued at resilient seated valve in resilient seal gate valve and is expected to reach a market value of resilient gate valve by y gate valve, with a CAGR of cast iron gate valve during the forecast period.
