Introduction and classification of the working principle of check valves
Check valve: Check valve is also known as one-way valve or check valve, its function is to prevent the medium in the pipeline Backflow. The bottom valve of the pump to close the water also belongs to the non-return valve category. The valve that opens or closes on its own by the flow and force o...Read more -
( Valve design ) Bidirectional cryogenic floating ball valves have changed the design of cryogenic systems
Until now, cryogenic application scenarios requiring two-way valve sealing have mainly used two types of valves, namely globe valves and fixed ball valves/top mounted fixed ball valves. However, with the successful development of the two-way cryogenic ball valve, system designers have obtained a...Read more -

The difference between forged and cast valves
Casting valve is cast into the valve, the general casting valve pressure grade is relatively low (such as PN16, PN25, PN40, but there is also high pressure, can be to 1500LD, 2500LB), most of the caliber is more than DN50. Forging valves are forged out. They are generally used in high grade pipel...Read more -
The characteristics of ball valves and butterfly valves
Ball valves and butterfly valves are two important categories of valves and are widely used. The ball valve requires strict sealing at high temperature and high pressure and low flow resistance. Butterfly valves are mainly used for working conditions with low pressure and low sealing requirements...Read more -
Steel/Metal Industry: Iron Ore and Steel Prices Climb to Record Highs
Iron ore prices have reached an all-time high, with China’s domestic steel product prices also soaring to record highs. Although the summer off-season is ahead, the uptrend in steel prices is likely to continue if relationship troubles between China and Australia linger and if China’s plans to cu...Read more -
[Actuator] Electric and pneumatic actuators: comparison of performance characteristics
Electric and pneumatic actuators for pipeline valves: It seems that the two types of actuators are quite different, and the choice needs to be made according to the power source available on the installation site. But in fact this view is biased. In addition to the main and obvious differences...Read more -
