The butterfly valve is usually less than 90° from full open to full close. The butterfly valve and the butterfly stem themselves have no self-locking ability.
Lift type check valve body shape and globe valve (and globe valve general), so its fluid resistance coefficient is larger.
Installation position, height, inlet and outlet direction must meet the design requirements, the connection should be firm and tight.

Butterfly valve is a single-board air valve, which has the advantages of simple structure, convenient processing, low cost and simple operation, but poor adjustment accuracy.
The ball of the ball valve is floating. Under the action of medium pressure, the ball can produce a certain displacement and compress on the sealing surface of the outlet end t...
In all kinds of valves, ball valve flow resistance is the least, full diameter ball valve open, the ball channel, valve body channel and connecting pipe diameter equal and into ...

The thrust bearing reduces the friction torque of the stem, which can make the stem operate smoothly and flexiblyfor a long time.
Metal body lined valves: such as rubber lined valves, fluorine lined valves, lead lined valves, plastic lined valves, enamel lined valves.
The fluid resistance is small, and its resistance coefficient is equal to that of the pipe segment of the same length. Simple structure, small volume, light weight.
