Japan's pneumatic high vacuum ball valve coil is short circuited 2. The opening pressure difference of angle stroke pneumatic valve is very large
The opening pressure difference of angle travel valves is very large. Because the torque of the drive shaft caused by the cooperation of materials on the valve core or valve body is very small, it can bear a large pressure difference.
In order to prevent valve body parts from working under cavitation conditions Δ P< Δ PT, if it is necessary to Δ P> Δ PT, more than two valve body parts can be connected in series, so that the differential pressure is distributed on two valve body parts, so that the differential pressure of each valve body part Δ P is less than Δ PT, so that cavitation can be avoided.
