API Standard Butterfly Valve 12 inch Lug Worm Gear Lock Butterfly Valve – Tkok Valve API Standard butterfly valve is a 12 inch lug type worm gear butterfly valve with a lock. The following picture shows the triple eccentric structure produced by Tkok Valve. The API Standard butterfly valve, API609 standard, lug type butterfly valve, manual worm gear operation, and butterfly valve with a lock. The lug butterfly valve produced by our company is a fully solid pressure hole, and there is another type on the market that is hollow in the middle. This greatly reduces the weight of the valve body, thereby saving costs. However, for high pressure, large diameter lug butterfly valves, their installation stability may be affected. The API Standard butterfly valves produced by our company are

Best Butterfly Valve Manufacturer in China Industrial valves are widely used and are an important part of petroleum, chemical, water conservancy and other industries. According to market surveys, it is expected that by 2025, there will be 90 million industrial valve manufacturers. How to choose among many valve manufacturers? It is particularly important that you think the right industrial valve manufacturer. However, there are more and more choices of industrial valves, but the problems that plague us also follow. How to choose a suitable valve manufacturer among many industrial valve manufacturers will be very difficult. If you have such troubles, then you have come to the right place, in this article, you will talk about getting China’s top butterfly valve manufacturers and making the right

Basic knowledge of flange butterfly valve The flange butterfly valve introduces the self sealing design concept, in which the connection between the valve office and the valve shaft adopts the patented pull-out pin structure. The valve] is characterized by reliable sealing, bi-directional sealing, tight connection and no loosening, so that the valve can be used for a long time. Its features are as follows: Bidirectional sealing Generally, due to its structure, the traditional butterfly valve can not be well sealed under the working pressure in the opposite direction (not conducive to the sealing direction). At present, there are no mandatory provisions on two-way sealing in relevant national standards. This is due to: 1. Adopt self sealing design concept The valve disc seal is directly embedded

Operating principle and installation instructions of butterfly valve The relationship between the opening of butterfly valve and the flow is basically linear. If it is used to control the flow, its flow characteristics are also closely related to the flow resistance of the piping. For example, the diameter and form of the valves installed in the two pipelines are all the same, and the flow rate of the valves will vary greatly with the loss coefficient of the pipelines. If the valve is in the state of large throttling range, cavitation is easy to occur on the back of the valve plate, which may damage the valve  15° For external use. When the butterfly valve is in the middle opening, the opening shape formed by
