Precautions for the use of triple eccentric metal seated butterfly valve
Triple eccentric hard-sealed butterfly valves are generally metal seated butterfly valves, which have an eccentric metal sealing structure. Sealing forms include metal-to-metal sealing, stainless steel plate and graphite composite plate sealing ring to metal sealing, etc. The driving methods are mainly electric, manual, turbo rod transmission, pneumatic and so on. The triple eccentric hard-seal butterfly […]
Correct installation method of pneumatic gate valve
Good valve products also need correct use and maintenance to ensure a good working condition and service life of the product, and pneumatic gate valves are no exception. The working state of the pneumatic gate valve directly affects the operation of the engineering system. Pneumatic gate valves have been widely used in metallurgy, petrochemical and […]
How to extend the service life of stainless steel metal seated butterfly valve
In general, we are most worried about the problem of stainless steel metal seated butterfly valves is rust. This is the common concern of the majority of users for metal products. In fact, stainless steel material itself is not easy to rust, but stainless steel materials are also divided into five categories, such as ferritic […]
Why is austenitic stainless steel magnetic
In the procurement case of austenitic stainless steel butterfly valves or gate valves, we can often find an interesting phenomenon. Customers carry magnets with them to check whether the material of the product is genuine. I think it is really “stainless steel” if it can’t be absorbed, and it’s faked with “stainless iron” if it […]
Structure and applicable working conditions of electric butterfly valve
Electric butterfly valve is one of electric valve and electric regulating valve. There are mainly flange type electric butterfly valve and wafer type electric butterfly valve, which are classified according to the connection method of electric butterfly valve. The electric butterfly valve is usually composed of a quarter-stroke electric actuator and a butterfly valve through […]
What to consider when choosing a suitable resilient seated gate valve
The soft-seal /resilient seated gate valve is widely used. It is favored by users because it overcomes the product defects such as poor sealing and rust of ordinary gate valves. The soft sealing gate valve has a unique elastic seat seal to achieve a good sealing effect. The soft sealing gate valve is easy to […]
Reasons and fixing for Leakage of the seat of the metal seated Gate Valve
The metal seated gate valve is well used in high temperature and high pressure media, but it also requires high quality due to the particularity of the working conditions, and the sealing problem that makes users most concerned about. What are the main reasons for leakage on the sealing surface? What measures can we take? […]
What kind of centerline wafer butterfly valve is a high-quality butterfly valve
There are many types of butterfly valves. Today we mainly want to discuss the centerline wafer butterfly valve, which is our more common type of butterfly valve. It has a wide range of applications, and currently there are many manufacturers of soft-seal wafer type butterfly valves. However, the quality and appearance of these butterfly valve […]
Comparison of the characteristics of wafer butterfly valves and flanged butterfly valves
To find out what is the difference between the wafer butterfly valve and the flange butterfly valve, let’s take a look at the comparison of some characteristics of the wafer butterfly valve and the flange butterfly valve. The biggest difference is of course that the flanged butterfly valve has two more flanges, and the wafer […]
Can a gate valve be used for oxygen as the medium?
If the soft-sealed gate valve you purchase will be used for oxygen media, the manufacturer will usually advise you not to do so, and inform you that it is prohibited to use gate valves in oxygen media pipelines in the specification. What is the reason for this requirement? In fact, this is mainly related to […]
