Under the condition that it is necessary to ensure the safety performance and stability of transportation in the pipe network, and try to avoid leakage problems, the selection of valves needs to be very cautious. In the valve category, the frequency of use of control valves is relatively high, such as electric valves and pneumatic valves, and the price on the market can be said to be different. So what are the determinants of the price of electric valves and pneumatic valves in control valves?

主要原因就是控制阀的型号规格、型号有所不同所凸显出的功能及其适宜的管网又是有所不同的。为了可以满足有所不同管网的要求，多种型号规格的制作开发促使其可以在行业中取得更为普遍的运用。型号规格的有所不同其市面的市面价格当然又是有所不同的。同规格同型号阀门中，通常电动阀门价格高于气动阀门。

The secondary reason is that the manufacturers and manufacturers are different, and their costs are different, so the market price is different. This also makes the price point highlight the trend of high and low, after all, the production process of different manufacturers and the quality of the valves they make are different. These are the fundamental reasons for the difference in price.

In addition, it has a direct impact on the material of the control valve. The valve function created by the valve of different materials is quite different. For example, it includes valves made of 304 stainless steel, which are corrosion-resistant and resistant to rust. Valves made of this material often have a competitive advantage over other valves. The price of electric valves and pneumatic valve actuators and the whole set of valves also plays a decisive role, the principle and valve price are the same, the price of different brands is different, and the price of different control methods is not the same.

Based on the above explanation, can we understand what are the determinants of the price of electric valves and pneumatic valves in control valves? When choosing this kind of product, we must pay attention to avoid screening according to the price, but to choose an economical and practical valve is a wise choice. This determines whether the selected valve can fully perform its maximum function and ensure its service life.
