Duty valves for classification and use

Ningbo Fenfa Valve Co.,Ltd | Updated: Oct 14, 2016

Corrosion protection valve is divided into four main categories: stainless steel valves, copper-lined valves, valves, plastic valves. By valve of structure type stainless steel valve up, General valve are can made stainless steel, General has stainless steel needle type valve, and stainless steel put material valve, and stainless steel ball valve, and stainless steel gate, and stainless steel as valve, and stainless steel check back valve, and stainless steel butterfly valve, and stainless steel sparse valve, and stainless steel electric female valve, and stainless steel water control valve, and column plug valve, and spin plug valve, and forged steel valve, and Harbour valve, and unloading valve, and safety valve, and Regulation valve, and valve, and Regulation valve,. Stainless steel valves with integral anti-fluoride antirust characteristics, whether both valves and valve corrosion, stainless steel valve high-pressure and high-temperature products can be produced, but the cost is high. Main chemical, construction, electricity and other fields, the media may be on fire, steam, oil product, nitric acid, acetic acid, and other media.

And line with fluorine valve are lined with fluorine floodgate valve, fluorine lined globe valves, lined with fluorine non-return valve, fluorine-butterfly valves, lines with fluorine diaphragm valve and other products. And line with fluorine valve is generally used in the chemical industry, construction, water conservancy, has a good preservative. Inside lining fluoroplastics lined valves, valves for carbon steel and cast iron, valve outside no corrosion, there is pressure in the low pressure range limited, so the price is cheaper compared to stainless steel.

Copper valve with ball valve, gate valve, globe valve, check valve, plug valve, generally used for oxidation of bad working conditions, seawater, such as oxygen plant, ship, equipment, building and waited. Has a good resistance to oxidation and corrosion.

Plastic valves are gate valves, ball valves, diaphragm valves, globe valves, check valves, butterfly valves and other products, mainly used in the construction and chemical sites. Fluorine plastic valves have good anti-rust-proof characteristics compared with fluorine valve relative to that. But low price, light weight.
