1. By structure According to the structure, it can be divided into trunnion ball valve, floating ball valve and flexible ball valve.According to the installation location,can be divided into top entry ball valve and side entry ball valve. 2. By actuator According to the ball valve actuator, can be divided into electric actuated ball valve,hydraulic actuated ball valve,pneumatic actuated ball va…

How do Crogenic Valves work? As its name suggests, cryogenic valves are designed to be used in very cold applications. They are thus most popularly used by companies that work with Liquefied Natural Gas (LNG) or Compressed Natural Gas (CNG). For instance, the oil and gas industry frequently uses cryogenic temperature ranges starting at -238 degrees Fahrenheit (-150 degrees Celcius). Additional…

Wafer butterfly valves and flanged butterfly valves are two common types of butterfly valves. Both types of butterfly valves have a very wide range of applications, but many friends cannot distinguish the difference between a wafer butterfly valve and a flange butterfly valve…

Single eccentric butterfly valve: In order to solve the problem of squeezing between the butterfly plate and the valve seat of the concentric butterfly valve, the single eccentric butterfly valve is produced. …

Wafer and flange are two connection methods. Wafer type is cheap, the price is roughly 2/3 of the flange. When choosing imported valves, use the wafer type as much as possible, and the price is cheap. Lightweight.…

Unidirectional sealing butterfly valve is that when the front of the butterfly plate of the butterfly valve is closed, it must face the flow direction of the medium; the medium only flows in one direction, and there must be an arrow indicating the flow direction of the medium on the valve body.…

The all-metal two-way pressure butterfly valve adopts a three-eccentric structure. It is completely sealed by the torque provided by the driving device. The valve can be reliably sealed under high and low pressure. That is, an angle eccentricity is added to the double eccentricity of the ordinary metal hard seal butterfly valve.…

The traditional metal hard seal butterfly valve is used to realize the on-off and flow control components of the pipeline system, and it is extremely widely used in many fields such as petroleum, chemical industry, metallurgy, hydropower and so on. In the known butterfly valve technology, the sealing form is a sealing structure, and the sealing material is rubber or polytetrafluoroethylene. But de…
