In water treatment equipment, the following valves are commonly used:Stop valve (check valve): used to control the switch of fluid to prevent fluid backflow or reflux.Regulating valve (regulating stop valve): used to adjust the flow, pressure or temperature of the fluid. The valve opening can be adj Read More

The butterfly valve itself does not have a fixed flow direction. However, the flow direction requirements of the butterfly valve and its design and use are affected by the medium.When using a butterfly valve, its flow direction depends on the pipeline system and the flow direction of the fluid. When Read More

The failure of pneumatic butterfly valve pneumatic actuator not working may be in the following situations: 1. Air source problem: Check whether the air source is supplied normally and confirm whether the pressure meets the requirements of the actuator. If the air source is normal, the air sour Read More

The circular butterfly plate that rotates with the valve stem opens and closes to complete the activation action. The pneumatic valve is mainly used as a cut-off valve. According to the structural characteristics of the pneumatic butterfly valve, it can also be designed to have the function of regul Read More

At present, butterfly valves, as a component used to realize on-off and flow control of pipeline systems, have been widely used in many fields such as petroleum, chemical industry, metallurgy, hydropower, etc. In the known butterfly valve technology, the sealing form mostly adopts a sealing Read More

Valve sealing material is an important part of valve sealing. It serves as the direct contact surface of valve sealing. What are the valve sealing materials?1.Synthetic rubberThe comprehensive properties of synthetic rubber such as oil resistance, temperature resistance, and corrosion resistance are Read More

Butterfly valves can be divided into pneumatic butterfly valves, electric butterfly valves, manual butterfly valves, etc. Butterfly valves are a kind of valve that uses a circular butterfly plate as an opening and closing part and rotates with the valve stem to open, close and regulate the fluid channel. The characteristics of the industrial butterfly valve are that it can withstand high temperatures, has a high applicable pressure range, has a large nominal diameter, the valve body is made of carbon steel, and the sealing ring of the valve plate uses a metal ring instead of a rubber ring. Large high-temperature butterfly valves are manufactured by welding steel plates and are mainly used in flue ducts and gas pipelines for high-temperature media. Read More
