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 […]
Two-way triple eccentric butterfly valve
The two-way hard-sealed butterfly valve is a valve product that has been developed rapidly in recent years. From the earliest centerline butterfly valve to the later triple eccentric sealing butterfly valve to the current triple eccentric two-way sealing structure, the hard sealing butterfly valve has greatly reformed and improved its own sealing performance. In the […]
Purchasing precautions for handle butterfly valves
When purchasing handle butterfly valves, it is not enough to only know the product specifications, categories and working pressure requirements, and it is impossible to achieve a good balance. Because different handle butterfly valve manufacturers have their own corporate standards and product personality, and some non-standard production to meet different customer requirements, it is unscientific […]
Instructions for the safe use of resilient seated flanged butterfly valves
The resilient seated flanged butterfly valve has the characteristics of small opening torque, flexibility and convenience, labor-saving and energy-saving. The sealing form of the soft seal has reliable performance and can achieve no leakage. Therefore, the use of flange soft-seal butterfly valve is very wide, and it has its presence in all major pipeline systems, […]
What is a triple eccentric metal seated butterfly valve
The triple eccentric metal seated butterfly valve is classified from the multi-level metal seated butterfly valve. Named because of the triple eccentricity structure. Its sealing performance is as good as the soft sealing butterfly valve, and it can maintain a good seal even in a high-pressure and high-temperature environment. It is often used for heating, […]
