Forged steel gate valves are designed for reducing, and compared with the diameter of the cast steel gate valves flow to be smaller, but the pressure and temperature range is higher than the cast steel valves, sealed performance is much better than cast steel gate valves, longer life, medium flow direction as well as other gate valve is not restricted. 1. Forged steel gate valve fluid resistance small, sealing surface corroded by medium Chong brush and small. 2. Forged steel gate Industrial Valves is suitable for Class150 ~ 2500, the working temperature - 29～425℃( Carbon steel) Or - 29～500℃( Stainless steel) Can be applied to cut or connect piping small-bore pipe road, in the media. 3. Butt welding forged steel gate form is simple, structure length is short, make good manufacturability, wide application scope. 4. Ram is vertically placed in the body, and cut-off valve disc was put in the valve body level, thus structure length shorter than globe valves. 5. Forged steel gate valve body internal media channel is straight, don't change the direction of flow medium flows through the gate, so the fluid resistance is small. 6. The flow direction of medium socket forged steel gate valve is not restricted, disturbed flow, reduce the pressure. Fully open sealing performance is very good sealing surface erosion is small. 7. Forged steel gate valve movement direction and perpendicular to the direction of flow can be fully open and close. Choose different material, can be respectively suitable for water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, and other media. Cast steel valves and belong to steel valves, forged steel valve what the difference? Cast steel valves and forged steel valves in appearance is easy to difference, cast steel valve is silver appearance, forged steel valves are black appearance. They are in addition to the difference in the appearance of color, the nature of what the difference? Here is a brief introduction. Firstly, cast steel valve is not capable acid-base and it can only be used on the ordinary pipe, and can resistance to high pressure forged steel valves, factory can use it in some high temperature, such as: power plant, chemical plant can use this type of valve. Two, second forging steel much more detailed than cast steel gate valves organization and better performance in the mechanical properties and casting organization is an organization of coarse grains, forging is refined grain, another popular way: forged steel gate valve mechanical performance is good, some toughness is better, if the composition is the same, the forged steel of high corrosion resistance, high bearing capacity. Compared with cast steel has obvious superior performance. Three, the price difference, forged steel valve price must be higher than the price of cast steel gate valve is, 'adjust measures to local conditions', according to different needs to decide to choose which kind of appropriate valves, truly let every money to produce the biggest value.
Nowadays, the adoption of wedge valve in resilient seated valve industry is quite common.
