20` Titanium Butterfly Valves - Case Study
A SlurryFlo client near South Africa had been utilizing Titanium butterfly valves to vent steam from their flash vessels. Due to the vapour also containing acids and fine particulates, the butterfly valves were quickly compromised and removed from service after 1 month. If the erosion damage was determined unrepairable (see Fig 1), a new butterfly valve was installed in its ...

Off-center Sanitary Butterfly Valve Advantages
Offset sanitary butterfly valves, sometimes referred to as disc valves, are generally closer to ball valves than traditional quick-install butterfly valves in terms of sealing and application. When closed, although the disc is also vertically flowing, the disc of the original axis position is slightly offset. Such valves therefore have greater advantages than the traditional quick-install ...

Precautions for Installing Sanitary Butterfly Valve
Compared to the normal butterfly valve, the sanitary butterfly valve has a higher sanitary level. In other words, it uses different materials and processes. Therefore, the sanitary butterfly valve is sophisticated equipment, its transport and installation must not fail or fall, so as not to damage. When installing it, you should pay attention to the following points: 1. Sanitary butterfly valve ...

Butterfly Valve
Are you looking for a professional butterfly valve supplier? Butterfly valve is operated through the 90 degree rotation of the butterfly plate and can be used in the pipeline for regulating and stopping media. The disc of the butterfly valve is perpendicular to the direction of medium flow. The user can adjust the flow of medium by opening or closing the butterfly plate. Butterfly valves are ...

Why Buy Ventilation Butterfly Valve from China?
Ventilation butterfly valves are available in manual, electric and pneumatic applications. The ventilated butterfly valve is machined into a seal ring using the same material as the valve body. The applicable temperature depends on the material selection of the valve body. The nominal pressure is ≤0.6MPa, which is generally suitable for industrial, metallurgical, environmental protection and ...

Influences of Temperature on High Vacuum Butterfly Valve
When high vacuum butterfly valve is used, temperature has great influences on its performance. High temperature impacts on high vacuum butterfly valve: When the valve is used in the scope of creep temperature, prestressing force on bolts falls due to flanges, bolts and gaskets loosening. Flange connection may also have the same phenomenon under the condition of temperature gradient. For this, ...

The General Scope of the Butterfly Valve
Generally, in throttling, regulating and controlling of mud medium, short structural length and fast opening and closing speed is required. Therefore, the butterfly valve is recommended in low pressure situation. 1. The following circumstances apply butterfly valve: two-bit regulation, narrow channel, low noise, cavitation and gasification, small leakage, as well as containing corrosive media. ...

Learining how to Choose Materials for Gas Valves
The materials and the quality of gas valves are so important that their disqualification will lead to leakage in-or-outside the body of the valve. If the strength, rigidity and overall performance of the components of the valve body cannot meet the requirements or even break, it will result in the spillage of gas and explosion. Therefore, material and quality are the most critical part during the ...

Wafer vs. Lug-Style Butterfly Valves
A butterfly valve is a type of quarter-turn valve that controls the flow of a product in a pipeline. From pharmaceuticals to manufacturing and food processing, the valve has a variety of applications and can be used to limit solid, liquid, or gas material flow. Butterfly valves are usually grouped into two types: lug-style and wafer-style. These mechanical components are not interchangeable and ...

Innovative Designs of Sanitary Butterfly Valves
Sanitary butterfly valves are flow control devices that are used to drive the water jet or other fluid through a funnel. In this admiration, it looks a lot like the ball valve. Anyway, instead of using a ball as life, use a plate that is embedded in the middle of the funnel. A pole is integrated through the circle for the interface with the stained actuator on the outside of the funnel. What ...

Features of Sanitary Butterfly Valves
The disc and the sanitary butterfly valve body can be in spheroidal cast iron or in steel. At this valve, when it is in the open position, small localized losses of pressure occur, while strong turbulence and vibrations are created in case of partial closure. Therefore, it is not very suitable for regulation. The maneuvers of the small diameter butterfly valves can be done directly by hand with ...
