Types of Sealing Material of Electric Wafer Butterfly Valve
Electric wafer butterfly valves can be divided into soft-sealed butterfly valves and hard-sealed butterfly valves, which are distinguished according to the sealing materials of electric butterfly valves. The soft sealing butterfly valve’s sealing feature is that one side of the two sides is made of metal material, and the other side is made of elastic […]
Commonly used valve body materials of centerline wafer butterfly valve
The centerline butterfly valve can be controlled by a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, turbine, electromagnetic, electromagnetic hydraulic, electro-hydraulic, pneumatic-hydraulic, spur gear, bevel gear drive, etc. Under the action of pressure, temperature or other forms of sensing signals, it can act according to predetermined requirements, or simply open or close […]
Resilient seated vs metal seated wafer butterfly valve
The soft-seal wafer butterfly valve contains two characteristics, one is that the sealing form is a soft seal, and the other is the connection method is a wafer. Wafer butterfly valves are divided into soft sealing butterfly valves and hard sealing butterfly valves. Soft seal means that one side of the butterfly valve sealing pair […]
Is a gasket needed for installation of the resilient seated wafer butterfly valve?
Before understanding the problem of adding gaskets to the soft-seal wafer butterfly valve, let’s take a look at the main working conditions of the soft-seal wafer butterfly valve. It can be applied to water supply and drainage, gas pipelines such as food, medicine, chemical industry, petroleum, electric power, textile papermaking, etc. It is used for […]
Troubleshoot reasons for pneumatic wafer butterfly valves
The pneumatic wafer butterfly valve has a beautiful appearance and is matched with a pneumatic actuator. The valve plate and the valve shaft can be connected without a pin, and the medium is completely isolated from the valve shaft and valve body, which is simple and easy to maintain. Pneumatic wafer butterfly valves are widely […]
Advantages and Features of Center-lined Wafer Butterfly Valve
The centerline wafer butterfly valve is a kind of centerline butterfly valve, which has two characteristics of wafer connection and centerline sealing. Today, the advantages and characteristics of the centerline wafer butterfly valve are based on the flange butterfly valve. details as follows: Pressure Level The centerline wafer butterfly valve generally does not have a […]
Precautions for installation of pinless wafer butterfly valve
The pinless wafer butterfly valve contains two connection methods, one is pinless and the other is wafer. A pinless butterfly valve is a pinless butterfly valve that does not use a pin to penetrate the connection between the valve plate and the valve stem. For comparison of pin butterfly valves and pinless butterfly valves, please […]
Is the EPDM butterfly valve suitable for water medium?
EPDM rubber butterfly valve fully meets the water working conditions and is a kind of soft sealing butterfly valve. It has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, color stability, electrical properties, oil-filling properties and fluidity at room temperature. It can be used in ozone-resistant, weather-resistant, and ultraviolet-resistant […]
How to choose the material of flanged gate valve seat
The sealing surface of flanged gate valve is an important working surface for the valve to block the medium and control the fluid. The quality of the sealing surface determines whether the valve is guaranteed to have no internal leakage, impermeability and other direct influence factors, which can be said to determine the service life […]
Evolution of the Sealing Surface of the Triple Eccentric Butterfly Valve
The triple eccentric butterfly valve is one of the butterfly valves. Its unique sealing form and sealing structure are continuously improved and upgraded through the product to obtain a better sealing effect. There have been great reforms in high temperature and corrosion resistance. Let’s take a look at its product upgrade process. The butterfly valve’s […]
