Recently, the Organisation for Economic Co-operation and Development (OECD) released its latest mid-term economic outlook report. The report expects global GDP growth to be 5.8% in 2021, compared with an earlier forecast of 5.6%. The report also predicts that among G20 member economies, ChinaR...Read more -
The basis for choosing the butterfly valve electric actuator
A. Operating torque The operating torque is the most important parameter for selecting the butterfly valve electric actuator. The output torque of the electric actuator should be 1.2~1.5 times the maximum operating torque of the butterfly valve. B. Operating thrust There are two main struc...Read more -
What are the ways of connecting the butterfly valve to the pipeline?
Whether the selection of the connection method between the butterfly valve and the pipeline or equipment is correct or not will directly affect the probability of running, dripping, dripping and leaking of the pipeline valve. Common valve connection methods include: flange connection, wafer conne...Read more -
Introduction of valve sealing materials—TWS Valve
Valve sealing material is an important part of valve sealing. What are the valve sealing materials? We know that valve sealing ring materials are divided into two categories: metal and non-metal. The following is a brief introduction to the use conditions of various sealing materials, as well as ...Read more -
Installation of common valves—TWS Valve
A.Gate valve installation Gate valve, also known as gate valve, is a valve that uses a gate to control the opening and closing, and adjusts the pipeline flow and opens and closes the pipeline by changing the cross section. Gate valves are mostly used for pipelines that fully open or fully close t...Read more -
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 -

The main points of valve selection—TWS Valve
1. Clarify the purpose of the valve in the equipment or device Determine the working conditions of the valve: the nature of the applicable medium, the working pressure, the working temperature and the control method. 2. Correctly select the type of valve The correct choice of valve type is a pre...Read more -
Butterfly valve installation, use and maintenance instructions—TWS Valve
1. Before installation, it is necessary to carefully check whether the logo and certificate of the butterfly valve meet the requirements of use, and should be cleaned after verification. 2. The butterfly valve can be installed at any position on the equipment pipeline, but if there is a transmiss...Read more -
