Overview
BV100 butterfly valves are widely used in semiconductors, flat panel displays, crystalline silicon solar energy, and industrial processes to control downstream pressure in chambers.
Product Details
innovation points
Dual channel self matching pressure sensing technology
Supports dual channel vacuum gauge signal acquisition, compatible with ± 15V or ± 24V vacuum gauge power supply, and can automatically switch ranges according to process requirements.
L-V-P pressure control technology
The pressure control unit records the relationship between pressure and valve opening in the process environment, using a combination of position, velocity, and pressure three loops. At the same time, it dynamically calculates the pressure to position ratio, position to pressure ratio, target pressure position, and estimated time to reach the target pressure, actively intervening in changes in valve opening to achieve rapid and stable pressure control.
Servo drive technology
Adopting a customized servo control on-chip system, the butterfly plate is positioned faster through multi-point slope control algorithm, and the switch response time can reach 0.2 seconds.
