Choosing the Right Cryogenic Valves
There are five types of cryogenic valves that are ideal for cryogenic media. Each of these types has its own set of characteristics that make them suitable in some applications and unsuitable in others. 1.Globe Valves. Called such due to their spherical shape, these valves have an internal movable disc -- the obturator -- that rotates at 90 degrees to the plane of its coordinated body seat.… -
What are the types of ball valves?
According to the ball valve material, can be divided into stainless steel ball valve, cast steel ball valve, alloy steel ball valve etc.… -
How do Crogenic Valves work?
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… -
The difference between wafer butterfly valve and flange butterfly valve
Wafer butterfly valves and flanged butterfly valves are two common types of butterfly valves.… -
What is the difference between single, double and triple eccentric butterfly valves
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. … -
Under what circumstances do we need to use wafer butterfly valves?
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.… -
What is the difference between bidirectional and unidirectional of butterfly valve?
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.… -
Triple-eccentric structure of bidirectional pressure butterfly valve
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.…
