New development of valves under carbon capture and carbon storage
Driven by the “dual carbon” strategy, many industries have formed a relatively clear path for energy conservation and carbon reduction. The realization of carbon neutrality is inseparable from the application of CCUS technology. The specific application of CCUS technology includes car...Read more -
The difference between OS&Y gate valve and NRS gate valve
1.The stem of the OS&Y gate valve is exposed, while the stem of the NRS gate valve is in the valve body. 2.The OS&Y gate valve is driven by the thread transmission between the valve stem and the steering wheel, thereby driving the gate to rise and fall. The NRS gate valve drives th...Read more -
Difference Between Wafer and Lug Type Butterfly Valve
A butterfly valve is a type of quarter-turn valve that controls the flow of a product in a pipeline. Butterfly valves are usually grouped into two types: lug-style and wafer-style. These mechanical components are not interchangeable and have distinct advantages and applications. The follo...Read more -

Common faults and preventive measures of butterfly valves and gate valves
The valve continuously maintains and completes the given functional requirements within a certain working time, and the performance of maintaining the given parameter value within the specified range is called failure-free. When the performance of the valve is damaged, it will be A malfunction wi...Read more -
Can globe valves and gate valves be mixed?
Globe valves, gate valves, butterfly valves, check valves and ball valves are all indispensable control components in various piping systems today. Every valve is different in appearance, structure and even functional use. However, the globe valve and the gate valve have some similarities in appe...Read more -
Where the check valve is suitable.
The purpose of using a check valve is to prevent the reverse flow of the medium, and a check valve is generally installed at the outlet of the pump. In addition, a check valve should also be installed at the outlet of the compressor. In short, in order to prevent the reverse flow of the medium, a...Read more -
