Overview
The HA multi spring thin film actuator is the driving mechanism of the CV3000 regulating valve, which has the characteristics of small size, light weight, and easy operation and maintenance.
The HA multi spring thin film actuator converts the output pressure of pneumatic control instruments into changes in push rod displacement. Therefore, as long as it is connected to the valve body of the regulating valve, the valve core can be moved to the position corresponding to the input signal. The actuator is a multi spring thin film actuator with a compact structure and high output force.

Type of action
Positive effects: HA1D, HA2D, HA3D, HA4D
Reaction: HA1R, HA2R, HA3R, HA4R
Note: 1. Positive actuator: As the supply pressure of the thin film chamber increases, the actuator push rod extends outward.
2. Reaction actuator: The supply pressure of the membrane chamber increases, causing the actuator push rod to retract inward.
