People consider when choosing steam control valve for many years has been a number of traditional factors, such as pressure rating, pressure drop, flow medium, temperature, and cost, etc. However, things changed a lot over the past 10 years, the steam engine valve design made a lot of progress, the cost effectiveness of production process features than ever before has been very different, this makes many traditional factors must be considered when choosing the valve before the importance of the has been greatly weakened. Dynamic characteristics of although some traditional factors is still important, but they only focus on 'static' performance of the valve. In fact, they are on the 'table' to measure the results gained by the valve, but the result is difficult to explain the valve in the actual operation conditions will show what kind of performance. Traditional theory holds that carefully adjusting static factors will make the valve ( Thus the whole loop) For good performance. Now, however, we recognize that this is not always the case. Researchers and producers to tens of thousands of times of performance examination, as much as 50% in valve ( Many of them by considering the traditional factors and selection) For optimization control loop performance failed to have much effect. Subsequent research has shown that the dynamic characteristics of to reduce process variability plays a very important role. In many of the key process, the range of the different valve to reduce process variability even a difference of 1% can greatly improve production efficiency and reduce waste, which can obtain the economic benefits of more than $1 million. Obviously, the economic benefits of such that we can completely negate the traditional approach, namely the original purchase price the only according to the valve to decide whether to buy. Second, the conventional wisdom always think, the improvement of process optimization always upgrade from the control room control instrument. However, the test data show that under the condition of using the same control instrument, dynamic characteristics of valve can significant impact on the circuit performance. If the control valve accuracy can reach 5%, then, spend a lot of money to configure a set of its control precision can reach 0. 5% of the advanced control instrument system does not have much effect. type in the search for a match the use situation of the valve, should first consider four basic types of the throttle valve, namely, cage ball valve, eccentric rotating ball valves, valve and butterfly valve. Cage ball valve adjustment form has a very wide range of species, thus can satisfy the requirements of most applications, making it become the preferred in the all kinds of valve. Cage ball valve adjustment piece has a lot of kinds, including balance adjustment, non equilibrium slice, adjustment of the elastic base seat, a constrained adjustment and full size pieces, etc. In many cases, a body of various configurations of TAB can be interchanged. Cage ball valve has a number of shortcomings. One is the valve size limit ( Usually a 16 inches) ; Second, with the same specifications of the line of sight valve ( Such as floating ball valve or butterfly valve) Compared to its capacity is low; Three is the selling price is higher, especially large-diameter cage ball valve. However, in terms of reduced flow variability, cage ball valve has excellent performance, often enough to make up for the defects. Rotating float valve flow is bigger than the same caliber of cage ball valve. While rotating the control range of floating ball Industrial Valves is greater than the cage ball valve, but it is still better than most other types of valves. Rotating floating ball valve to allow the pressure drop and the allowed temperature range is smaller than cage ball valve. Usually they pressure drop limit for 7. 0 x105kg/m2, suitable for use in the occasion of temperature below 398 ℃. Floating ball valve does not apply to easy up cavity of the liquid, and used in the gas of high pressure drop, often for a larger noise.
