Because the coil static characteristic is exponential, in order to achieve good control effect, the logarithmic curve regulating valve is usually used. Only by guaranteeing a certain degree of valve weight can the actual curve of the valve meet the requirements. Because the coil static characteristics are related to the temperature difference of water supply, … Read more

The static balancing valve is a regulating valve with a special function of digital locking. It adopts a direct-flow valve body structure and has a better equal percentage flow characteristic. It can distribute the flow reasonably and effectively solve the existing problems in the heating (air conditioning) system. Uneven heat and cold at room temperature. … Read more
The dirt separator is a component widely used in petrochemical process pipeline. Its function is to prevent the impurities in the pipeline medium from entering the transmission equipment or precise parts, so as to cause production failure or affect the quality of products. The dirt separator is installed on the main water supply pipe at … Read more
The Structure and Material Selection of Angle Type Control Valves Valve chamber cushioning design When the pulp passes through the valve core, it must first be decompressed to facilitate the cushioning effect. With cushioning design, the inner chamber can reduce the medium pressure instantaneously, and the pulp will not wear and wash the valve body … Read more
1. Appearance The appearance is different. Trunnion ball valve body with a fixed shaft on the bottom. And if the ball valve body has a device for injecting grease, it is basically a trunnion.However, can we say it must be a floating ball valve if it is without injecting device? Of course not, small size … Read more
